Swipe to see what Kevin Mandia is building after Google’s $5.4 billion acquisition of Mandiant. His new cybersecurity startup, Armadin, just raised $255.5 million in a Series B co-led by Andreessen Horowitz and Accel. The round values the company at more than $2.5 billion, roughly 13 months after its founding. Armadin uses teams of AI agents to test companies’ defenses, looking for weaknesses and combining them into routes attackers could actually exploit. Human security experts help guide the work. The goal: show businesses where someone could break in—and help them close those gaps before real attackers get there. The latest round brings Armadin’s total funding to approximately $445 million.
