Matt Hartman, the deputy executive assistant director for cybersecurity at the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency, will step down on May 31, ending his nearly two decades of service.
In a LinkedIn post on Tuesday, Hartman confirmed his departure and reflected on his journey from joining DHS as an IT specialist for the National Protection and Programs Directorate to holding various leadership roles within the agency.
“NPPD and CISA don’t just represent the most critical chapter of my career — this agency is and will remain a critical component of my identity,” the cybersecurity official said.
