VectorCertain LLC today announced that its SecureAgent governance platform has been independently validated to detect and prevent 100% of autonomous multi-step AI exploitation attempts before execution, a capability that directly addresses the cybersecurity risks that prompted an emergency meeting between Treasury Secretary Scott Bessent, Federal Reserve Chair Jerome Powell, and CEOs of major U.S. banks on April 8, 2026.
The validation, conducted across 1,000 adversarial scenarios spanning eight sub-categories of autonomous multi-step exploitation, achieved 100% recall (810 of 810 attacks detected and prevented) with zero false negatives and a 98.9% specificity rate. The testing was conducted using Anthropic's Claude API with independently generated scenarios never seen during system development, and the results are statistically certified at a 3-sigma lower bound of ≥99.65% using the Clopper-Pearson exact binomial method.
The threat class validated—T1 Autonomous Multi-Step Exploitation—is the core capability demonstrated by Anthropic's Mythos model, which can autonomously chain three to five vulnerabilities into a complete attack sequence. This capability triggered the emergency meeting at Treasury headquarters, where regulators demanded that systemically important banks take precautions against AI-powered cyberattacks. Bloomberg and CNBC reported that the meeting included CEOs from Goldman Sachs, Citigroup, Morgan Stanley, Bank of America, and Wells Fargo.
According to VectorCertain's internal testing, every EDR system on the market is architecturally incapable of preventing such attacks because they detect actions after execution rather than before. MITRE ATT&CK Evaluations Enterprise Round 7 confirmed this structural limitation, finding 0% identity attack protection across all nine evaluated vendors. SecureAgent's 5-layer governance pipeline evaluates every AI agent action before execution, blocking multi-step exploit chains in under 10 milliseconds.
The eight sub-categories tested include multi-vulnerability chaining, recon-to-exploit sequences, cross-system lateral movement, automated privilege escalation, financial system exploit chains, infrastructure cascades, autonomous tool creation, and long-range multi-session campaigns. In every category, SecureAgent achieved 100% detection and prevention. The platform's MRM-CFS-SG ensemble of 828 segments confirmed kill-chain fusion analysis, detecting that each blocked action was the first link in a chain that would have progressed through privilege escalation, credential theft, and data exfiltration.
VectorCertain's Tier A External Exposure Report is available for free, providing organizations with a zero-touch assessment of their externally observable attack surface, including leaked non-human identities, exposed credentials, and MITRE ATT&CK coverage gaps. The report requires no customer involvement and delivers results within hours.
Joseph P. Conroy, Founder & CEO of VectorCertain LLC, stated, "Treasury Secretary Bessent and Fed Chair Powell didn't summon bank CEOs to an emergency meeting because autonomous multi-step exploitation is a theoretical risk. They summoned them because it's a current capability—one that every EDR vendor on earth scores 0% against on identity attacks. SecureAgent is the only platform with validated data proving it can detect and prevent 100% of these exploit chains before the first action fires."
The validation is part of VectorCertain's MYTHOS Certification Program, which covers all seven Mythos threat vectors. The company's internal MITRE ATT&CK ER8 evaluation across 14,208 trials achieved a TES score of 1.9636 out of 2.0 (98.2%) with zero failures. SecureAgent also scored 100/100 in safety benchmarking compared to Block's Goose at 36/100, with a response time of 3.6 milliseconds versus 72,435 milliseconds.
