Mandiant’s founder just raised $190M for his autonomous AI agent security startup

Kevin Mandia, founder of Mandiant (sold to Google for $5.4B in 2022), has launched a new AI-native cybersecurity startup called Armadin. The company raised $189.9M in combined seed and Series A funding led by Accel, with participation from GV, Kleiner Perkins, Menlo Ventures, 8VC, Ballistic Ventures, and the CIA's venture arm In-Q-Tel. Armadin aims to build autonomous AI security agents to counter AI-powered cyberattacks, which Mandia warns will be able to complete attacks in minutes that previously took days. The co-founding team includes former Google Cloud Security and Mandiant executives.
