Kevin Mandia says AI attacks operate at machine speed, and Armadin has found over 90 production zero-days since January 2026.
After 30 years in cybersecurity and building Mandiant, Kevin Mandia says he returned because AI is reshaping the field. At Armadin, AI agents attack customer networks to identify exploitable risks; the company says it has found more than 90 zero-days in production systems at Fortune 500 customers since January 2026. Mandia describes AI attacks as far faster and broader than human intrusions, while warning that open models are already capable enough to amplify less-skilled attackers. Armadin’s “hyperattack” maps networks and repeatedly checks for changes, while its planned blue-team tools will work with platforms such as CrowdStrike to apply rapid defensive controls. Mandia argues conventional penetration testing will give way to continuous, AI-driven red teaming, and that security operations will need autonomous prevention, detection, and response. He also discusses lessons from the Hugging Face incident, the need to combine AI with experienced security expertise, and the pressure to fund and scale Armadin quickly as the market changes.
