What happened

Shares of Akamai Technologies (NASDAQ:AKAM) jumped as much as 15.7% higher on Wednesday morning, boosted by a strong third-quarter earnings report (downloads PDF).

So what

Analysts had expected the content delivery network operator to report earnings of $0.61 per share on sales of almost $572 million. Instead, revenue rose 6% to $584 million. On the bottom line, earnings increased by 10% and landed at $0.68 per share.

The gains were driven by 19% year-over-year sales growth in the performance and security segment, including 46% higher revenue in the cloud security part of that division.

Now what

Akamai's business model is not the performance-focused service it used to be, as the security aspects of distributed content delivery networks have started taking the upper hand.

"As the cyber-attacks from last week demonstrate, enterprises need solutions capable of defending against massive botnets that are exploiting millions of online devices," said CEO Tom Leighton in a prepared statement. "This is an area where Akamai's unique architecture and ongoing investments in global scale and security innovation continue to make a critical difference."
