Cybersecurity investment firm Allegis Capital announced on Friday that former FireEye CEO David DeWalt is joining as a venture partner.
DeWalt served as president, chief executive officer and director of McAfee from April 2007 until February 2011, after Intel’s surprise $7.68 billion acquisition of McAfee. DeWalt resigned from his role as President at McAfee in July 2011.
Founded in 1996, current investments by Allegis include Area 1, Bracket Computing, Cyber GRX, E8 Security, RedOwl, Signifyd, Synack, tCell.io and vArmour. Allegis is also a founding partner in Columbia, Maryland-based cybersecurity incubator DataTribe.
DeWalt joined FireEye as chairman of the board of directors in May 2012, and took on the role of CEO in November of 2012. He stepped down in June 2016, handing the reigns over to current CEO Kevin Mandia.
DeWalt, 52, is the sixth cyber security executive serving as a venture partner at Allegis, a 21-year-old early stage venture firm that invests exclusively in cybersecurity startups.
He is also a board member at identity and access management firm ForgeRock, vice chairman of ForeScout Technologies, a San Jose cybersecurity firm focused on network-connected devices, and a board member of cloud software firm Five9.
DeWalt is also a director of Delta Air Lines, and recently joined industrial cybersecurity startup Claroty as chairman of the board of directors.
“Dave has operated at the top of the cyber security market for many years and is a superlative addition to an already-impressive group of venture partners,” said Robert R. Ackerman Jr., founder and managing director of Allegis Capital. “Cyber is a market where you can’t have too much expertise.”
