BlogMachine-Speed Attacks Break Human-Speed Defenses: Why Zero Trust Must Be Architectural
CyberStrikeAI used 44 autonomous AI agents to industrialize exploitation across 19 organizations in under 24 hours. When threat actors automate the full kill chain, manual SOC triage collapses. Dr. Chase Cunningham warned us years ago: trust is a vulnerability, and defense must be deterministic.
BlogWhy Your AI Agent Evaluations Are Bad Statistics
Frontier agents score 80%+ on short benchmark tasks and still collapse in production. The problem is not the reasoning model—it is evaluating multi-turn stochastic systems with static point estimates.
