Armadin raises $255.5 million in Series B funding round
Security startup Armadin announced on Thursday that it raised $255.5 million in a Series B round led by Andreessen Horowitz and Accel.
Founders history and new team
Kevin Mandia founded the company after previously leading Mandiant, which Google acquired for $5.4 billion in 2022. The latest investment includes Bain Capital Ventures, Redpoint, and other major firms joining Andreessen Horowitz and Accel as lead investors.
Funding timeline and total capital
This Series B round occurred just six months after the firm secured a $190 million Series A in March. The company has now collected more than $445 million in total funding since its inception.
New security approach for AI
Armadin provides enterprises with always-on security by using agentic swarms to chain together vulnerabilities instead of traditional penetration tests. This method helps organizations find and seal holes before bad actors or rogue AI agents can exploit them.
