FireEye stock sold off 15 percent Wednesday, just one day after the cybersecurity company's outlook fell below expectations—but CEO Dave DeWalt still defended its performance.
"Obviously, first of all, you know, FireEye's been one of the fastest-growing companies, not just in security but in all of enterprise," he said. "We went from, I think, $57 million in 2011 in billings to now an estimated $580 million just three years later now in 2014. I mean, the company 10x'd in 12 quarters. Even if you go back just eight quarters, the company quintupled, or 5x'd, in just a two-year period."
On CNBC's "Fast Money," DeWalt said the company was performing well.
"And, you know, if you look at the top line, this company's performing amazingly, and we continue to take a ton of market share every quarter," he said.
