Artificial intelligence-native cybersecurity firm Armadin announced a record-breaking $189.9 million in seed and Series A funding. The capital will accelerate the development of its AI-driven attack simulation platform and expand engineering and research teams.
Founded in 2024 by Kevin Mandia, the visionary behind Mandiant, Armadin's software simulates real-world cyberattacks to identify and validate exploitable weaknesses in enterprise environments. This approach contrasts with traditional scanning methods by modeling adversary behavior through automated agents.
"The AI shift is changing cybersecurity more rapidly than any transition in history," stated CEO Kevin Mandia. "In a world of machine-speed attacks, defense must become autonomous. We are building the most formidable offense to give organizations the greatest defense."
The platform employs distributed AI agents to emulate attack phases, probing systems and configurations in a controlled environment. This allows for the identification of chained weaknesses that could lead to network compromise.
Armadin's system generates validated attack paths and reports, enabling security teams to observe vulnerability interactions and test the impact of infrastructure changes on attacker progression. The software integrates with existing enterprise environments, including cloud infrastructure and identity systems.
The funding round was led by Accel Partners LP, with participation from GV Management Company, Kleiner Perkins, Menlo Ventures, In-Q-Tel, 8VC Management, and Ballistic Ventures.
