About
Armadin was founded in 2025 in the United States by Kevin Mandia — former CEO of Mandiant, widely regarded as one of the world's foremost cybersecurity incident response firms — with a mission to fight AI-powered cyber threats with AI-native offensive and defensive capabilities. The company was built on the premise that as adversarial AI lowers the barrier to sophisticated attacks, the only effective defense is an equally capable AI system that can simulate, anticipate, and respond to attacker behavior autonomously.\n\nArmadin's platform uses agentic attacker swarms — coordinated AI agents modeled on real adversary tactics, techniques, and procedures (TTPs) — to conduct continuous red teaming, vulnerability discovery, and attack surface validation against enterprise environments. Unlike periodic penetration testing engagements, Armadin's agentic approach delivers persistent, automated adversarial pressure that reflects the reality of modern threat actors operating continuously. The platform integrates with existing security operations workflows to surface findings in actionable formats for blue team remediation.\n\nArmadin raised a record $189.9M across its Seed and Series A rounds in March 2026, an extraordinary funding level for a company founded just one year prior. The scale of funding reflects both Kevin Mandia's exceptional credibility in the cybersecurity market and the urgency enterprises feel around AI-native threat readiness. Armadin enters a market where legacy red team tooling and manual penetration testing are increasingly inadequate against AI-assisted adversaries, positioning it as a defining company in the next generation of offensive security.
