John C. Burris, 57, led Sourcefire since 2008. Company officials credited Burris, a former top executive with
and AT&T, with helping it achieve profitability and expand its product offerings. Burris had been on medical leave since July.
Martin Roesch, Sourcefire's founder and chief technology officer, is serving as the company's interim CEO until a successor for Burris can be found.
According to a
filing, Sourcefire accelerated its retirement agreement with Burris, vesting a portion of his stock-based compensation worth approximately $3.7 million. The company also agreed to pay the premiums on his life insurance policy — about $4,000 a year — until he turns 65, the SEC filing said.
