AI-native autonomous offensive security for enterprises and government
Armadin is a Palo Alto-based AI-native cybersecurity company building an autonomous offensive security platform that deploys agent swarms to chain low-severity weaknesses into validated kill chains, showing enterprises and government customers the attack paths adversaries could use in production. Led by CEO Kevin Mandia, the company emerged from stealth about seven months before October 2026 and reports running agentic attack campaigns for Fortune 500 and government customers. Its Series B co-led by Andreessen Horowitz and Accel valued the company at over $2.5 billion on $445 million total funding.
