The Cybersecurity and Infrastructure Security Agency (CISA) is facing significant upheaval as nearly all top officials exit the agency. This wave of departures includes the departure of Matt Hartman, the Deputy Cyber Chief, who has announced his decision to step down. The situation has escalated with the exit of several division chiefs, which raises concerns about the stability of national cybersecurity efforts. With these high-profile losses, CISA is grappling with broader agency reduction plans that could undermine its mission.
