Armadin Raises Record $189.9 Million to Deploy AI Attacker Swarms Against Hyperattacks

New updates have been reported about Armadin.

Armadin has secured a combined $189.9 million in Seed and Series A funding, in what investors describe as the largest early-stage capital raise in cybersecurity to date, to accelerate deployment of its AI-native attacker platform. Led by Accel, with backing from Google Ventures, Kleiner Perkins, Menlo Ventures, In-Q-Tel, and existing investors 8VC and Ballistic Ventures, the round positions Armadin to scale an autonomous system designed for AI-driven “Hyperattacks” that can overwhelm traditional, human-centered defenses.

Under CEO Kevin Mandia, Armadin is building an agentic attacker swarm that uses specialized AI agents and custom models to emulate advanced human threat actors, continuously probing enterprise environments and producing board-ready evidence of what can truly be exploited. The founding team, which blends veteran red-team operators with AI researchers, aims to turn decades of offensive security know-how into continuously learning models that can operate at machine speed across an organization’s attack surface, providing a de facto system of record for exploitable risk and offering enterprises and national security stakeholders a way to prepare for the coming wave of AI-accelerated cyber campaigns.
