Protecting your data and technology systems has become paramount in today's world, where everything is connected all the time. The typical breach costs a company an average of $4.4 million in damages, so the stakes are high.
The global cybersecurity market is poised to grow, surpassing an estimated $350 billion by 2030. Investors have placed a hefty valuation premium on cybersecurity stocks, but SentinelOne (S +3.67%) has been a very notable exception.
Shares of SentinelOne, which utilizes artificial intelligence (AI) to protect its customers from cyber threats, trade down over 80% from their late 2021 all-time high. The stock's steep slide arguably makes it the most undervalued AI stock on Wall Street right now.

Struggling to stand out in a crowded field
SentinelOne specializes in endpoint security, which protects devices (endpoints) in a network. Its autonomous AI-powered technology proactively finds potential threats. The company has received recognition for its products and serves a laundry list of large corporations.
However, the cybersecurity industry is very complex. There are various types of security, and almost every niche is highly competitive. There are often new entrants to the field, as well as entrenched players trying to expand in the name of growth.

Key Data Points
SentinelOne has successfully grown, but has taken some bumps and bruises along the way. In 2023, the company lost some key employees to its rival CrowdStrike Holdings. SentinelOne is also still an unprofitable business. It just doesn't have much pricing power at this point due to all the competition.
The selling may have gone too far
Here's the good news. SentinelOne is generating positive free cash flow and still has $650 million in cash versus almost no debt. In other words, SentinelOne has financial staying power. And to be clear, the company continues to grow.
Analysts see SentinelOne ending its current fiscal year right at $1 billion in revenue, with estimates calling for about 20% growth next year. The company isn't anywhere near the size or market share of CrowdStrike or Palo Alto Networks, but the stock has become eye-poppingly cheap relative to them.

Compared to these other cybersecurity stocks, SentinelOne is basically trading for cents on the dollar. Now, the stock isn't a guaranteed home run: SentinelOne must continue to grow and demonstrate that it can stick around in this competitive landscape.
But if the company can win back some of the market's confidence, SentinelOne's growth and massively discounted valuation are an excellent springboard for strong investment returns. I wouldn't go as far as calling SentinelOne a buy-and-hold-forever stock, but rather a contrarian stock idea, a bargain with compelling upside that's worth checking out.
