Matt Coose, the director of the Homeland Security Department’s National Cybersecurity Division’s Federal Network Security Branch, is leaving government after seven years.
DHS sources confirm Coose’s last day is July 14. He plans to join the private sector, but sources didn’t have any details of where he was going.
Sources say Danny Toler would assume Coose’s responsibilities at least in the interim. Toler joined DHS in April as the director of Federal Network Resilience. He came to DHS from the State Department.
Coose’s departure continues the revolving door at the Office of Cybersecurity and Communications in DHS.
Since January, four senior executives have come to DHS, and since the fall, almost the entire management team that oversees cybersecurity in the National Programs and Protections Directorate (NPPD) is new.
Meanwhile, over the last year, DHS lost five senior officials. Phil Reitinger, the deputy undersecretary of NPPD; Greg Schaffer, the assistant secretary in the Office of Cybersecurity and Communications; Sean McGurk, the director of the National Cybersecurity and Communications Integration Center in NPPD and Nicole Dean, the director of the National Cybersecurity Division, all left for new jobs in the private sector, while Adm. Michael Brown, the director for Cybersecurity Coordination, retired after 32 years in government.
Coose has been the director of the Federal Network Security Branch for more than three years. In that role, he helped implement the Trusted Internet Connection (TIC) initiative, developed updated metrics for the Federal Information Security Management Act (FISMA), including continuous monitoring, and oversaw a host of other cyber related programs.
He previously worked as the director of the engineering project management office at DHS.
Coose graduated from West Point in 1991.
