Cybersecurity veteran Kevin Mandia has secured $255.5 million for his latest startup, Armadin. The company announced the Series B round on Thursday at a valuation of more than $2.5 billion.
Andreessen Horowitz and Accel led the financing round. Additional participants included Bain Capital Ventures, Redpoint, 8VC, Ballistic Ventures, Google Ventures, In-Q-Tel, Kleiner Perkins, and Menlo Ventures.
Series B follows a Series A round
The new financing arrives just six months after Armadin collected $190 million in a March Series A round. Total fundraising for the enterprise security startup now exceeds $445 million.
Mandia previously founded Mandiant. That cybersecurity startup sold to Google for $5.4 billion in 2022.
Agent swarms replace traditional penetration tests
Armadin targets enterprise customers by providing continuous security through automated agent swarms. The platform reimagines defense testing for the artificial intelligence era.
Traditional penetration tests rely on hired security professionals who attempt to breach systems and report discovered vulnerabilities. Armadin deploys always-on agentic swarms that chain together vulnerabilities to hack systems.
The system aims to help organizations identify and patch security holes before malicious actors or rogue agents from artificial intelligence labs exploit the same agentic technology against them.
