In a major reshuffle of the company’s top management, FireEye has appointed existing president Kevin Mandia to take over as CEO from David DeWalt, who will stay on as executive chairman. DeWalt was previously also board chairman.

In addition, Mandiant president Travis Reese has been named FireEye president, while Mike Berry, chief financial officer, gets the additional responsibility of chief operating officer. Board member Enrique Salem has been appointed lead independent director.

These moves were made with a view to strengthening the company’s position globally and to “prepare for growth opportunities going forward,” according to FireEye.

Mandia is the founder of Mandiant, which FireEye acquired in 2013.

“With the combination of FireEye services, intelligence, and products, I believe that our global threat management platform is poised to dominate the future of cybersecurity, and we’ve taken steps to create a senior leadership team that can build on this opportunity,” Mandia said.

These executive changesl take effect on June 15
