Frenos is the first AI-native OT penetration testing platform, purpose built for critical infrastructure, defense, and industrial control environments. We enable organizations to safely and continuously test the defensibility of their operational technology without touching production systems. Our platform combines digital twin modeling, AI adversary reasoning, and attack path simulation to uncover real-world exposures, validate controls, and prioritize mitigations all without disruption. By emulating the tactics, techniques, and procedures (TTPs) of nation-state and ransomware actors, Frenos reveals exactly how adversaries could move through your OT environment and what defensive actions matter most. Built by OT security experts and offensive practitioners, Frenos empowers red teams, blue teams, and CISOs to shift from periodic assessments to continuous validation moving beyond visibility to measurable resilience. Whether deployed as a laptop-based assessment tool or an enterprise-grade continuous red teaming platform, Frenos delivers the automation, consistency, and insight needed to stay ahead of modern OT threats.
