Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Thank you, Bill. We are pleased to report another strong quarter. In Q3, we delivered 63% year-over-year revenue growth, 54% billings growth, and 15% free cash flow margins, all while investing for high growth. While most public SaaS companies are happy to get to Rule of 40, we again exceeded the Rule of 70 based on revenue growth and free cash flow margins.

With our increased guidance today, we expect to achieve the Rule of 80 for the full year. We are not only delivering excellent growth. We are also delivering strong profitability. We are disciplined in making investments for innovation and go-to-market scale.

With the breadth and depth of our ever-expanding zero trust platform, we can efficiently sell to our growing base of enterprise customers. We believe our clear focus on securing large enterprises makes us the partner of choice for our customers' zero trust security journey. While there are broader macro challenges and economic uncertainties, we have seen an increase in large multiyear commitments for multiple product pillars of Zscaler platform as periods of uncertainty can act as a catalyst for change. This, coupled with growing cyber threats such as ransomware are driving IT leaders to transform security from [Inaudible] mode security to zero trust architecture.

In this environment, customers cannot risk transformational and mission-critical projects with immature offerings from unproven vendors. As the pioneer and category leader in Security Service Edge or SSE with the widest and deepest offerings, Zscaler is the trusted partner for vendor consolidation, cost savings, increased user productivity, and better cyber protection. We are adding new Global 2000 customers at a record pace. In the last two quarters, we added close to 80 G2K customers.

Now 40% of the Fortune 500 and 30% of Global 2000 companies trust Zscaler to secure their digital transformation. Approximately half of our Global 2000 customers have bought ZIA and ZPA, and I am excited to report that ZPA has surpassed over $200 million in annualized revenue. In Q3, we had significant growth in new $1 million-plus ACV deals across major geographies and customer verticals. We are seeing an acceleration in multiyear, multiproduct pillar deals as enterprises are racing to transform their business.

We provide a path for large strategic customers to ramp into larger and longer commitments for our entire transformational platform, not just for elements of it. This is driving a strong growth in bookings with the total value of our committed future revenue reaching a key milestone. It has surpassed $2 billion. Now let me highlight some customer deal wins during the quarter.

As I mentioned before, I believe all customers will ultimately purchase ZIA, ZPA, and ZDX for all users. This quarter, we have seen ample evidence that customers are buying ZIA, ZPA, and ZDX together, providing zero trust security for users with fast user experience. In a new logo win, a global 500 food services conglomerate headquartered in Europe, purchased ZIA ZPA and ZDX for all 100,000 users, leveraging our globally distributed SSE platform. This customer is consolidating dozens of different vendors, point products across hundreds of locations in 45 countries.

The customer was most excited about having a single zero trust security policy framework for in-line inspection across its business units in every location. Given the significant cost savings, up-level security and improved user experience across the company, the CEO and CFO signed off on this non-budgeted four-year commitment. In addition, they started a paid pilot for our zero trust for workloads offering for this sizable AWS footprint, which we are very excited about. Next, in an upsell deal, a global 10 oil and gas customer headquartered in Europe.

After deploying ZIA and ZPA for 100,000 users, purchased ZDX for all 100,000 employees. ZDX is delivering immediate value by reducing the customers' time to troubleshoot performance issues by 50% to 80%, while consolidating 40 legacy performance point products. In addition, the customer upgraded to a newly introduced ZPA transformation bundle that includes browser isolation, application protection and deception services. This is a four-year deal that increased the customer's annual spend by over 70%.

This customer's journey with Zscaler is remarkable. I remember sitting with the chief architect in their office, finalizing the purchase of our ZIA professional bundle six years ago. Since then, the annual spend has increased over 14 times to well over $10 million. Next, we look forward to working with them on zero trust for workloads.

In an upsell win, a Fortune 50 bank in Asia that has deployed ZIA for over 50,000 users purchased ZPA and ZDX, for all 50,000 employees. This is another example of a large customer buying ZIA, ZPA and ZDX for all users. While the immediate objective for this deal was to replace a legacy multi-vendor VPN infrastructure, ZPA was selected to implement zero-trust access by establishing an application-level policy, where users connect to specific applications now to a network, hence, achieving app segmentation without having to do legacy network segmentation. ZPA did not just replace VPN.

It's eliminating the need for the entire inbound DMC, including DDoS protection, app delivery controllers and firewalls, generating a payback on the Zscaler purchase within six months because of the substantial ROI. Even in a tougher macro, Zscaler can help reduce cost while driving transformation. Our integration with Microsoft's E5 suite across ZIA and ZPA was also an important decision factor for them. This latest purchase more than doubled the customers' annual spend.

ZIA, ZPA and ZDX together form a complete solution to implement zero trust for users. Our next immediate big opportunity is zero trust for workloads powered by the same core ZIA and ZPA technology. Let me highlight a few exciting wins in this area. An existing Fortune 100 financial services customer with ZIA deployed for 60,000 users purchased zero trust for workloads to protect 50,000 workloads spanning across multiple data centers and public clouds.

This eliminates the need for virtual firewalls and site-to-site VPNs. This multimillion-dollar ACV deal is our largest workload deal to date and more than doubles the customers' annual spend. The customer protects both users and workloads under a single policy framework, enhancing their cyber protection, providing visibility and simplifying operations. Lastly, let me discuss the new customer purchasing all 4 product pillars together.

At a lead research university purchased our comprehensive ZIA, ZPA and ZDX offerings for 35,000 users and zero trustful workloads for over 3,000 workloads for the multi-cloud environment. their CIO's top priorities to eliminate the risk of legacy VPNs and lateral threat movement as universities are increasingly becoming a target for a somewhere and intellectual property effect. Also, a critical requirement for this win was our zero trust platform, meeting the criteria of zero trust framework as recommended by NIST we closed this three-year eight-figure deal through AWS marketplace. I'm very happy with our continued success in expanding our routes to market via cloud marketplaces.

Next, I'm excited to highlight U.S. federal government where we are having considerable momentum, driven in part by the president's executive order, we are seeing increased interest in our Zero Trust Exchange across all levels of the government. We are excited to help our country dramatically improve our security posture while significantly reducing legacy IT costs. We have the highest level of FedRAMP certifications for ZIA and ZPA.

In addition, ZPA is the only zero trust solution with DoD IL-5 certification. There are only a select few cloud companies that have this level of certification, and there's no other cybersecurity company at this level. IL-5 certification is an important differentiator for us. Let me highlight two new customer wins this quarter where this was an important factor plus, a defense contractor that purchased ZIA and ZPA in a six-year seven-figure ACV deal.

Second, a DoD unit also purchased ZPA for secure access to SAP instances in AWS GovCloud. Two important considerations for our ongoing success in the federal market are: first, ZPA is the only cloud security service with FedRAMP high authorization for zero trust remote access. We connect users to applications and not to the network eliminating lateral threat movement, a core principle of zero trust architecture that can't be achieved by next-gen firewalls or cloud VPNs; second, ZIA's proxy architecture, which inspects TLS encrypted traffic at scale, delivering superior security. Our proven track record, running the world's largest in-line security cloud makes Zscaler the obvious and trusted partner of choice for governments and enterprises.

We now have 288 customers exceeding $1 million in ARR, an increase of 77% year over year. We deliver a mission-critical service that requires unmatched reliability and availability for an in-line cloud. There is no compression algorithm for over 10 years of operational experience running such a cloud. An example of our proven scale is that Zscaler processes over 240 billion transactions in line per day, which is more than 20 times the number of Google searches per day.

Now let me share a few observations about our high net retention rate, which has exceeded 125% for the last six quarters. We made a number of investments in customer success services, technical account managers, partner services, and certification of partners, which together are driving a faster and greater adoption across our broad portfolio. We have a sorted blueprint for accelerating value delivery, which is driving upsells. All of these investments result in happy customers, demonstrated by our Net Promoter Score or NPS of more than 70%, which is more than two times that of an average SaaS company.

Next, let me now highlight our rapid pace of innovation. After having built the most comprehensive platform to provide zero trust for users. We are now expanding it for zero trust for workloads. Unlike scores of vendors who offer point products for cloud-native apps.

Zscaler has developed a fully integrated CSPM, CIEM and infrastructure as core scanning with a common back end and fully correlated actionable dashboard. Gartner calls his functionality CNAPP, but we have moved beyond CNAPP by integrating the threat and data awareness from ZIA and ZPA. We will be highlighting it and other innovations at Zenith Live, our Annual Cloud Summit next month. We enhanced our AI/ML engine for ZDX, our fastest-growing new service to leverage billions of telemetry points from millions of users to improve digital user experience.

It cannot only automatically figure out what and where performance issues are but can also provide information about the quality of voice, video, and screen sharing due to our integration with Microsoft Teams and Zoom. We have also integrated ZDX with ServiceNow, making customer end user support far more efficient. ZDX also got certified and became available on our Federal Cloud. Our threat labs security research team is tracking over a dozen APT groups and getting better reconnaissance about the tools and behavioral patterns, resulting in higher order threat intelligence.

This specific threat intel, coupled with a massive cloud effect from 240 billion transactions and 300 trillion signals per day, enables Zscaler to deliver better threat protection than other vendors. Moving beyond users and workloads. We are now bringing zero trust to IoT and OT systems, a large emerging opportunity. Today, Siemens and Zscaler announced the availability of an integrated all-in-one solution to accelerate secure access to OT systems.

Our joint development with Siemens brings the benefits of Zscaler to factory and industrial control systems. We are thrilled to have Siemens a long-standing customer as a development and go-to-market partner. In closing, in spite of uncertain macro conditions, we continue to see strong demand for our services. We are in a strong financial position and we will continue to aggressively invest in our business.

We are focused on hiring and developing talent and creating a culture that rewards innovation at all levels. We have grown our global organization to approximately 4,500 employees who are energized by our shared mission to secure the hyper-connected world of cloud and mobility. We grew our total sales and marketing headcount by 54% year over year, and we remain focused on investing in our go-to-market machine. In today's competitive hiring market, Zscaler is a destination for top talent to drive continued growth in hiring and to build on Zscaler's high-performing hybrid work culture.

This month, we welcome Brendan Castle, Google's former global head of talent acquisition, as our new chief people officer. Brendan has proven experience in building highly motivated and productive teams at scale with app transformation already mainstream. Network and security transformation is also becoming mainstream, which we pioneered with our Zero Trust Exchange. We believe customers trust Zscaler more than any other provider for securing their cloud journey.

Recent uncertainty in the macroenvironment is driving customers to accelerate their network and security transformation with our integrated platform, resulting in a reduction in cost, complexity, and business risk. We are adding a record number of Global 2000 customers, know with 30% of Global 2000 and 40% of Fortune 500 customers trusting Zscaler. These demanding customers are making large multiyear commitments to our platform. We are not just growing rapidly at any cost, we are also profitable and delivering efficient growth.

We will continue our disciplined investment in innovation and growth to capture the large and growing opportunity ahead of us. Now I'd like to turn over the call to Remo for our financial results.

Remo Canessa -- Chief Financial Officer

Thank you, Jay. As Jay mentioned, we are pleased with the results for the third quarter of fiscal 2022. Revenue for the quarter was $287 million, up 63% year over year and up 12% sequentially. On a year-over-year basis, revenue growth exceeded 60% for the third straight quarter driven by strong customer demand for our zero trust platform.

CPA product revenue was approximately 18% of total revenue, growing 87% year over year. From a geographic perspective, we had broad strength across our three major regions. Americas represented 52% of revenue, EMEA was 33% and APJ was 15%. APJ continues to be our fastest-growing region with revenue growth of 105% year over year.

Our total calculated billings grew 54% year over year to $346 million, with billing duration comparable to a year ago and above the midpoint of our normal 10 to 14 months range. Our remaining performance obligations or RPO grew 83% from a year ago, to $2.216 billion. The current RPO is 49% of the total RPO. Our strong customer retention rate and our ability to upsell the broader platform have resulted in a high dollar-based net retention rate, which was, again, above 125%.

We had 288 customers paying us more than $1 million annually, up 77% and from 163 in the prior year. I'm very pleased with the pace at which we're adding these $1 million ARR customers. We increased by 37 customers in the quarter, the continued strength of this metric speaks to our large enterprise focus and the strategic role we play in our customers' digital transformation initiatives. We added 140 customers in the quarter paying us more than $100,000 annually, ending the quarter at 1,891 such customers.

Turning to the rest of our Q3 financial performance. Total gross margin of 80.6% was approximately flat quarter over quarter and year over year. Our total operating expenses increased 11% sequentially and 70% year over year to $204 million. Operating expenses as a percentage of revenue was 71%, compared to 68% in the year-ago quarter due to a partial return of T&E.

Operating margin was 9% and free cash flow margin was 15%. We continue to expect data center capex to be around high single-digit percent of revenue for the full year. We ended the quarter with over $1.66 billion in cash, cash equivalents, and short-term investments. Now moving on to guidance and modeling points.

As a reminder, these numbers are all non-GAAP, which excludes stock-based compensation expenses and related payroll taxes, amortization of debt discount, and amortization of intangible assets. We are once again increasing our guidance across all metrics. For the fourth quarter of fiscal 2022, we expect revenue in the range of $304 million to $306 million, reflecting a year-over-year growth of 54% to 55%, gross margins of 79%. I would like to remind investors that a number of our emerging products, including ZDX, workload segmentation, and CSPM, will initially have lower gross margins than our core products because we're more focused on time to market and growth rather than optimizing them for gross margins.

Operating profit in the range of $33 million to $34 million, we have more in-person events this quarter, including customer events, Zenith Live, and RSA conferences. Net loss on other income of $500,000, income taxes of $3 million; earnings per share of $0.20 to $0.21, assuming approximately $146 million to $147 million fully diluted shares. For the full year fiscal 2022, we are increasing our revenue guidance to approximately $1.078 billion for a year-over-year growth of 60%. Increasing calculated billings to a range of $1.425 billion to $1.43 billion for a year-over-year growth of approximately 53%.

Increasing our operating profit to a range of $106 million to $108 million. Increasing our earnings per share to a range of $0.64 to $0.65, assuming approximately $147 million to $148 million fully diluted shares. Free cash flow of $215 million, reflecting free cash flow margin of approximately 20% for the full year with a revenue growth outlook of 60% and free cash flow margin of 20%, we expect to operate at the rule of 80 for the full year. With customers increasingly adopting the broader platform with longer-term commitments, we plan to invest in capturing our large market opportunity, confidence in the durability of our business model with very high contribution margins, after the initial land and proven ability to retain and upsell to our enterprise customer base.

We will balance growth and profitability based on how our business is growing, and we'll continue to prioritize growth, which we believe is the best interest of our shareholders, employees, and customers. Operator, you may now open the call for questions.

Questions & Answers:

Operator

Thank you. [Operator instructions] Our first question comes from Andrew Nowinski of Wells Fargo. Your line is open.

Andrew Nowinski -- Wells Fargo Securities -- Analyst

Great. Thank you. Congrats on another amazing quarter. I wanted to ask about your federal demand.

Jay, I think you said you saw you're seeing considerable momentum in the U.S. Federal this quarter or this -- which seems to be an uptick from Q2, where I think it was maybe one of the underperforming sectors. So just wondering if you could comment on maybe what changed and what caused that uptick in demand this quarter ahead of the usual budget flush in calendar Q3?

Remo Canessa -- Chief Financial Officer

Andrew, I'll start it last quarter, Q2, our federal was low single digit of new and upsell. And in Q3, it was mid-single digit, so definitely an uptick. Also, on a go-forward basis, we do see federal as being an important contributor to Zscaler. We feel that we're well-positioned in the federal market.

I'll let Jay speak more to that.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yeah. Andrew, as you know, President's executive order is to implement zero trust architecture, and it's well aligned it actually aligns with what we have done. To be success in federal, you need two things. One, you need the right architecture, zero trust, which we have.

Two, unique FedRAMP certifications. And we have the highest FedRAMP certifications. And now there's a timing issue as well. White House issued a memo setting a time line for agencies to achieve zero trust architecture within two years.

These plans are being submitted and more budgets are becoming available. All of this is positive long-term development from our point of view. However, for opportunities always save time.

Andrew Nowinski -- Wells Fargo Securities -- Analyst

That's great. Thanks, guys. Keep up the good work.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Thank you.

Operator

Thank you. Our next question comes from Alex Henderson of Needham. Your line is open.

Alex Henderson -- Needham and Company -- Analyst

Great. Thank you very much. I've been listening to a lot of people trying to get into this zero-trust market. And one of the things that really strikes me is highly differentiated is, one, the policy implementation mechanics are so radically different than what you're doing versus the traditional perimeter defense.

And then second is the sharp increase in attacks that we're seeing in terms of encrypted traffic, received the report today talking about over a 300% increase in encrypted attacks over the last year. Can you talk to the relevance of those two data points or those two concepts relative to your platform? And how you solve that better than, say, alternative vendors? And in that context, can you just address Cloudflare's comments that they're getting more aggressive in this space? Thanks.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yeah. Thank you, Alex. So first of all, zero trust implementation. People sometimes build a little P&A play spend they call it zero trust.

What we built with Zscaler Private Access is a platform that it plays the entire inbound D&C. Literally, you need nothing between c-scale and the workload and application running. And in fact, on top of that, we further expanded to a browser isolation, app protection, interior deception and IM-based policy that can help you do segmentation. It's because of that you're winning CPE deal a big time.

So that's one part. The second part was a tax. So first of all, for someone to attack the need to find with our zero trust architecture, your applications behind the power they can even find. And with the next from are taxes, and this is impacted tax.

For that, you need a proper proxy architecture that actually terminate connection, look at the package and everything, decrypt them, find them and take care of them. For that, we have built a very, very highly scalable architecture that sets us apart that scales like nothing else out there. So it's a combination of these things. With 10-plus years of experience running a massive in-line cloud is what sets us apart from others.

Now regarding some of the competitors coming from CDN market are DDoS or DNS market, right, those guys generally have been focused on servers, we start focusing on users to start with. It takes a lot of time and experience to build our richness and breadth of functionality we have built with [Inaudible] and associated functionality. I think it will take a long, long time for someone to try to catch us. And we are setting.

We are innovating at a very fast pace.

Alex Henderson -- Needham and Company -- Analyst

Thank you very much.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Thank you.

Operator

Thank you. Next, we have Hamza Fodderwala of Morgan Stanley. Your line is open.

Hamza Fodderwala -- Morgan Stanley -- Analyst

Hey, guys. Thanks for taking my question. Just one question for Remo. I'm wondering if you can give us a little bit more color on how you're thinking about the margin trajectory going forward? It seems like you want to continue hiring against the market opportunity that you're seeing.

Zscaler has obviously been more of a destination for talent in the last couple of years. And particularly the incentive structure around the stock, a lot of employees have done well. How are you thinking about that incentive structure between cash and stock going forward, given that we're probably going to be in a more difficult equity market in general and just the pace of hiring relative to what you've done in the last couple of years?

Remo Canessa -- Chief Financial Officer

There are a lot of questions.

Hamza Fodderwala -- Morgan Stanley -- Analyst

Yeah.

Remo Canessa -- Chief Financial Officer

Yeah. Let me see if I can go through and just kind of give you my view and maybe Jay can tell that also. We -- currently, we're at the rule of 80. That's what we're projecting for this year.

And the way we define the rule of 80 is our revenue growth and also free cash flow margin. Our free cash flow margin this year, we're projecting to be 20%. It was 20% last year. So we're in a unique position to really take advantage of this market opportunity because we've got significant cash flow coming into the company as well as we're in the early stages of this market.

So we're going to continue to make investments as we go forward. Those investments are going to be across the board throughout the organization, and we're going to -- and our goal is to get to a $5 billion ARR company. So we're building the infrastructure in place to do that. And related to employees and incentives with the stock options and just cash incentives, the cash incentives that we talked about on the last call related to the frothy environment, last quarter with a lot of start-up companies and companies or PE-backed companies having really big packages.

So we adjusted our merit to reflect to get our employees at market levels. So from a cash compensation perspective, we're in pretty good shape. Regarding stock. Stock, all companies basically have decreased stock prices and -- what we're doing is we're taking a look at that.

No decisions made at this point regarding what we're going to do from a stock perspective. But what I can say is our stock-based compensation as we go forward, will decrease as a percentage of revenue. What happens is that when you get to a certain scale as a company and a very large company, their stock-based compensation becomes -- goes down. We'll follow the same path as the large companies, you'll see our stock base coming down over a period of time.

Regarding the pace of hiring, -- and again, we're seeing all the things that you're seeing related to the global macro environment. We're not seeing it. From our perspective, we are strategic for our customers. As Jay talked about, our deal sizes are getting large.

Our strategic nature and our engagement with our customers is increasing. So our plan is to continue the pace of hiring. And if we can increase the pace of hiring, we will. Now regarding color to -- related to operating profitability and also growth.

we'll put growth because, number one, we are mindful. Jay and I are mindful of operating profitability in world school, quite frankly, we look at the bottom line. So we see -- we see a huge market opportunity, huge we feel we're the leader in that market. We will continue to invest, and we'll do it on a prudent basis that we feel is the best interest of our shareholders and our employees.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

If I may add two quick comments to what Remo said, with very high gross margins and unit economics, it becomes easier for us to invest in businesses. Secondly, the hiring environment has -- is actually getting easier. We are hearing of high-flying companies that raise funding and multibillion-dollar valuations last year, they're starting to lay off people or freeze hiring, and companies that are spending to grow at any cost are now starting to slow down. So we will keep on accelerating our plan because our customers want to leverage Zscaler.

To accelerate their transformation because they want to be competitive NHI.

Hamza Fodderwala -- Morgan Stanley -- Analyst

Very helpful, gentlemen. Thank you for that.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Thank you.

Operator

Thank you. And next, we have Matt Hedberg of RBC Capital Markets. Your line is open.

Matt Hedberg -- RBC Capital Markets -- Analyst

Great. Thanks for taking my questions, guys. Congrats. Jay, what really stood out to me was the success in large deals and multiproduct sales.

I think especially impressive given the partner momentum in some of these large deals. Can you talk about the importance of hyperscalers? I believe you called out on an eight-figure deal. Is there more -- is there even more that you guys can do to drive even faster partner contribution? Because it really does feel like that flywheel is really kicking in well?

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yes. So the partner momentum comes from two sides. One is partners like Microsoft, who have been helping us even without fulfilling through marketplace. That momentum has been leveraged for the last several years.

Now it has extended over AWS quite a bit. So that's one area. The second area is being able to deliver orders through cloud marketplace. It is one more channel for us to revenue.

Our business through both AWS and Azure has been steadily growing, and these current viewed as a part of a clone transformation solution. So when it's focal through a marketplace channel, it often comes out of an annual cloud spend that's already committed by the customer with a hyperscaler. So that makes it actually easier in many ways. In Q3, with one of our largest deals through AWS marketplace.

And if you recall, we did a very large deal last quarter through Azure Marketplace, and we are training AWS and Microsoft sales teams. And I think there's a good opportunity to create more leverage. And these are generally larger deals. So you've seen our momentum in larger deals in the last two quarters, we have added almost 80 Global 2000 companies to our portfolio.

I mean that's pretty remarkable, and we don't see any slowdown.

Matt Hedberg -- RBC Capital Markets -- Analyst

Super excited. Thanks, guys.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Thank you.

Operator

Thank you. Next, we have Patrick Colville of Deutsche Bank. Your line is open.

Patrick Colville -- Deutsche Bank -- Analyst

Thank you so much for having me on and echo, everyone else's congratulations on a very impressive set of numbers. My question is on the billings guide, which to me was probably the standout metric of the quarter. So I think above probably where many investors were expecting. So very healthy there.

Can you just talk to what you guys are seeing in the pipes for fiscal fourth quarter and the health that I guess you underline the confidence to give that strong billings guidance for the fiscal year? Thank you.

Remo Canessa -- Chief Financial Officer

Yes. I'll start it. And Jay, if you'd like to contribute anything. We have a strong pipeline.

As we talked about, we're becoming more strategic. Our deal sizes are getting bigger. We review our pipeline with our sales organization. And based on our projections, we did give a strong guide, Patrick, which is basically up 6%, basically guide up.

The key thing is that with the world that's changed within this way for a while with applications in the cloud and users removal and workloads both in the cloud and on-prem and other locations, platform Zscaler created really addresses this market head-on. Also, the efficiency that we create for customers at a very attractive ROI. It's really what stands out. And so we're seeing with large customers that adopting more of the platform, as Jay has talked about, we're seeing that.

So it is basically a review of the pipeline and review what we feel we're comfortable to guide to.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yes. So I think what Remo said, our projection is always take into account our pipeline, our customer engagements. But at a qualitative level, as I talked to lots and losses, CIOs and CSOs, I mean there is a sense of uncertainty out there. And they're beginning to think about how do I do my cost and complexity reduction by consolidation.

And that's where we start becoming pretty important. And for that, customers are driving transformation. We help them with it. On top of that cyber is a big issue.

So when you bring all these things together, we become more important for them, and they start a discussion with, Jay, what all security products and networking products can I replace with you? And now, we are able to actually talk about a bigger set of products that need to be removed, which actually leads to a bigger part of platform to be bought. Now on top of that, it's interesting to see certainly on the high-flying private start-up companies, which would talk about all kinds of different hiring, how many employees, all that stuff is getting tempered down. That means the unnecessary noise in the market, it's expected to slow down. And it's fascinating to see people calling us from those start-ups already.

So we are bullish about the business.

Thank you. Next, we have Joel Fishbein of Truist. Your line is open.

Joel Fishbein -- Truist Securities -- Analyst

Thank you and I'll echo the congrats on the great execution this quarter. Jay, I just want to ask about workload segmentation. It sounds like your -- I know it's early days. You're very excited about it and have some good uptake.

I'm really interested in go-to-market around workload segmentation and actually IoT and OT. It doesn't seem like they're natural -- they have different buying centers inside of organizations than ZIA, ZPA, and ZDX. Love to hear how you're going to plan to go to market there and increase deal sizes around those specific areas.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Very good question. In Q2, we talked about how a number of our large customers are beginning to buy workloads, our zero trust of workloads, but at a small scale. This last quarter, we start to see them actually buying some very large orders in this area. So that's very encouraging now.

In terms of the buyer and the products, the cloud protection products can be put in two broad buckets. One, what Gartner now called CNAPP is a collection of CSPM, CI, and type of stuff. It's API-based security. It's a new area for everyone.

It's a simple to build, and we have a very good offering in that space. We revamped our CNAPP offering, which we'll be launching at Zenith Live next month. And parallel with that is zero trust workload, which is taking ZIA and ZPA technology and making it available for workloads because at flows need to talk to Internet that goes through ZIA engine. They need to talk to each other, which goes to ZPA engine.

This is bringing zero trust to workloads. Bringing the two together, in-line piece of it and API piece of it sets us apart from any other vendor in the market out there. Regarding buying centers, if you really look at it, if we were selling at a lower level, buying will be very different. No matter what -- who buys the product, when it comes to security part, CECL is definitely involved.

So our good relationship CECL are helping us with zero trust workload and cloud protection. Our relationship with Head of Networking are helping us because in the old world, you are extending your data center to cloud with all these dedicate link out there. The area, we are developing and building more relationship is the DevOps side of it. But since CECL relations are strong, it is helping us.

We are not creating an overlay team, but we do have product specialists. You need overlay teams when you're selling point products at low level. When we have been selling platform at a high level, I don't need to overlay teams. I do need product specialists, which we are hiring to work with our broad sales team.

Did that help?

Thank you. And next, we have Fatima Boolani of Citi. Your line is open.

Fatima Boolani -- Citi -- Analyst

Good afternoon. Thank you for taking my questions. Remo, this one is for you. in Jay's script, a lot of anecdotes around the multi-land transactions in the eight-figure deal momentum in the $1 million customer momentum.

So what I wanted to ask you was just from a booking standpoint, I think you've called out that you are seeing a bigger multi-year commitment from some of your customers. So we're certainly not seeing that impact on billings in terms of your invoicing duration. But I'm curious if you can comment or share any sort of observations on your backlog? And if there's any duration impact in there that we should be thinking about more critically? Thank you.

Remo Canessa -- Chief Financial Officer

Yeah. That's a great question. If you take a look at our RPO and CRPO growth on a year-over-year basis. Those are committed deals.

Our RPO growth was 83% and our CRPO growth was 75%. Related to duration, the duration was comparable on a year-over-year basis. There's no headwinds. We expect duration to be in that 10 to 14 months range.

So I mean, the key things from billings. Billings is calculated billings, which is calculated off of deferred revenue. So that's what we actually build. But we look at the RPO and CRPO growth rates, RPO is 83%, and CRPO at 75% growth rate on a year-over-year basis.

Now having said that, even though those metrics are outstanding, we still feel that billings is the best measure for Zscaler because we found that duration period from 10 to 14 months. That's -- so I hope that answers your question. I believe that answers your question. But the actual commitment that customers are making to Zscaler is quite impressive.

Fatima Boolani -- Citi -- Analyst

Very clear. Thank you, gentlemen.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

And Remo, if I may add one thing. This is an outstanding quarter from lots of customers doing multi-product pillar deal for multi-years, which is very exciting.

Operator

Thank you. Next question comes from Ben Bollin of Cleveland Research. Your line is open.

Ben Bollin -- Cleveland Research Company -- Analyst

Good afternoon, everyone. Thank you for taking the question. I wanted to go back to the topic around cloud marketplaces. Remo, can you quantify how much of the business is being transacted over cloud marketplaces today or how that has evolved? And then also interested in any way we should think about the margin implications of that business versus other sales channels? Thanks.

Remo Canessa -- Chief Financial Officer

Yeah. I mean not much business currently going through cloud new marketplace. There is business going through, but we see that as a very important channel for us. And related to margin, we expect good margins through a flat marketplace.

Jay, if you want to?

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yeah. But one thing that business through cloud marketplaces has been steadily growing over time. So that is very good. For us, I don't think the driver is what's the fulfillment channel for us.

I personally care about partners who actually helped me with strategic sales to the customer. When Microsoft accounting cancer able to sit together with the CIO and talk through a large deal. It is extremely useful. But it does help to get cloud hyperscaler sales team more engaged because they actually do compensate it for the business that flows through the channel part -- through cloud marketplace.

So we actually are putting more focus on training AWS and Microsoft sales team, so which helps them and helps us.

Ben Bollin -- Cleveland Research Company -- Analyst

Thank you. And next, we have Tal Liani of Bank of America. Your line is open.

Tal Liani -- Bank of America Merrill Lynch -- Analyst

Hi, guys. I have two questions. One, in general, but I'm trying -- I get this question along from investors. I'm trying to understand economic slowdown, what's the impact on your business? It's a little bit of a philosophical question, but it's a question we're being asked a lot, and I would like to hear your view on this topic.

And second, we are at times of focus on cash flow and margins. And I look at your operating margin in the last four quarters, -- it went down from 13% to 8.7% in the previous quarter, this quarter slightly recovered. And at the same time, your revenues went up by 50%, give or take. So we don't see much leverage on the margin.

And the question is if I pass forward two to three years, if I think about margin leverage and what needs to happen for you to have serious margin upside. Can you talk about the pros and cons of your operating margin? Thanks.

Remo Canessa -- Chief Financial Officer

I'll start with that. We absolutely do have leverage in the model. In a SaaS model with 80% gross margin, growing at the scale that we're growing we absolutely have no leverage. What we talked about is that with this large market opportunity, it would be a disservice to our shareholders and our employees if we try to drive top-line operating profitability at this stage.

Having said that, when you take a look at our free cash flow margin last year, it was around 20% or over 20%. And we're projecting free cash flow margin this year at 20%. So when you have that kind of free cash flow margin at the scale that we are, making the investments that we're making in the position that we are as a company in this very large market, there's no better use of our cash for our resources than investing in the business and really executing and trying to drive our top-line growth. Having said that, we will be mindful, we will be mindful.

If we wanted to drive operating profitability, it doesn't take much. But with our free cash flow margin where it is, we're very, very comfortable. Now from an economic slowdown perspective, Security is important. Companies basically are knocking out the attacks are going to keep coming, and they're probably going to increase.

Also, companies going through this downturn have to find areas to save money. We are efficient. Our ROI is absolutely outstanding. It is significant ROI with the highest level of security down to the deepest level.

And so from an economic slowdown perspective, we are not seeing it currently. Now can that change? It can. But right now, based on our pipeline, based on what we're seeing, and what we talked about, we're going to continue to hire at pace. Jay and I, as I mentioned before, have a lot of experience.

We've been -- we've seen the three downturns -- three or four downturns actually in our lifetime or careers. Zscaler is different. -- and we feel we're in a great position. We will take things into account all things but -- and driving operating profitability at this stage, it's really -- we will increase operating profitability as we go.

But we're going to be also trying to drive that top-line growth. Jay?

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yes. Two quick comments. First of all, I do believe there's uncertainties helping us because we are going to help customers with cost reduction and complexity reduction. And on the other side, our flagship [Inaudible] products, they have reached significant scale and are generating good margins.

But we are reinvesting that to drive the growth of new products. We have proven that when we brought ZPA on, we made it successful. We've seen -- we brought ZDX on. We're making it successful.

It's growing even faster than ZPA did, and we have high expectations from workload protection as well. So I think with such a large platform, we expect that we'll keep on growing fairly efficiently.

Tal Liani -- Bank of America Merrill Lynch -- Analyst

Got it. Thank you.

Thank you. Our next question comes from Roger Boyd of UBS Securities. Your line is open.

Roger Boyd -- UBS -- Analyst

Hey. Thanks. Thanks for the question and congrats on the results. Just a quick question on SD-WAN.

Historically, you've had some success tied to adoption there. I know Zscaler agnostic to how customers ultimately onboard to the Zero Trust Exchange. But with some of the SD-WAN vendors facing some disruption in share losses and potential change of ownership. How do you think about those changes in terms of potential opportunities or risks?

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yes. Before COVID came in, Zscaler used to start with, let's do network transformation. When COVID started two and a half years ago, SD-WAN went out the door, there's nobody working in the branch office and customers start to roll out Zscaler by downloading a lightweight agent and here it goes. So with that, the role of any network or SD-WAN became really insignificant.

Today, most of our customers roll it out or lapped our mobile with a lightweight agent they can work from home, they can work from office with SD-WAN, without SD-WAN. So we'll stay neutral to supporting SD-WAN vendors. Our sales processes are no longer led by SD-WAN. If a customer sales on rolling on SD-WAN, we are generally the preferred choice, and that's how we see it.

So we don't really see any changes in the SD-WAN marketplace impacting us.

Roger Boyd -- UBS -- Analyst

Got it. Thank you.

Thank you. Our next question comes from Joshua Tilton of Wolfe Research. Your line is open.

Joshua Tilton -- Wolfe Research -- Analyst

Hey, guys. Thanks for taking my question here. I don't believe you mentioned it in the prepared remarks, but can you talk about any impact to the business you're seeing either positive or negative from the Russia Ukraine prices?

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

Yeah. Russia, Ukraine. It was a bigger thing a quarter ago. I decided years ago not to sell in Russia.

Hence, we do not have any revenue exposure in Russia or Ukraine, but cybersecurity is a global threat. It's not a regional at -- our threat research team is tracking heightened cyber cat environment, which is making every CIO and CECL more nervous in this area. So this is driving the adoption of zero trust architecture and it is increasing our engagement with customers. More so in Europe, actually European customers are more worried about it while Americans are, too.

So we have some very large deals in Europe this quarter, including a couple of them I highlighted. We don't really see any negative impact of this conflict -- and we remain engaged with our customers to drive the transformation. They want to become agile, competitive player role there and then cyber on top of that. So I don't see any negative impact.

Thank you. The next question shall come from Rob Owens of Piper Sandler. Your line is open.

Rob Owens -- Piper Sandler -- Analyst

Great. Thanks for taking my question. I wonder if you guys could drill into the Siemens partnership a little bit. And I guess, Jay, more broadly, what you see as the opportunity in OT from where you sit? Thanks.

Jay Chaudhry -- Chief Executive Officer, Chairman, and Founder

OT plants and factories have been slow in changing typically plans take their own time, but all these critical infrastructure attacks and some threats have made it a priority. Vendors like Sims are big providers of 4P systems out there. They see this as an opportunity for really providing or should I say, taking fiber and PPN based security of OT systems to 0 trust-based security, where you no longer connect these OT networks and IT networks where you no longer need remote VPN to act the systems. So Siemens has worked with us over the last year or so.

They essentially shows us as a partner, we did joint development where we made our technology available on their hardened systems, and this combined solution of Siemens and ours is not available through our customers [Inaudible] I think it's a good opportunity for us. I think it's a matter of time when all IoT OP systems will embrace zero trust, and we are positioned well for that opportunity.

Rob Owens -- Piper Sandler -- Analyst

All right. Thanks.
