Built by former OT security practitioners, the no-cost simulated penetration test on-ramp leverages AI reasoning and digital twins to secure critical infrastructure without impacting production

FULTON, Md., May 5, 2026 /PRNewswire-ÌÇÐÄVlog/ -- As the cybersecurity world reels from the discovery of thousands of zero-days by Anthropic's "restricted" Claude Mythos model, , the only fully simulated AI penetration testing platform, today announced the launch of the , a free, one-day simulated penetration test for any organization defending critical infrastructure or operational technology. Frenos combines a cyber digital twin with an AI reasoning agent that thinks like an adversary to reveal every attack path, risk-free.

This is Frenos' response to the rapidly changing threat landscape AI has created. Anthropic's Project Glasswing and its Claude Mythos Preview have demonstrated AI agents that autonomously discover zero-day vulnerabilities at machine speed, with a 90-day disclosure clock already ticking. Annual penetration tests, severity-based prioritization, and reactive patching cannot keep up. The Mythos Readiness Assessment is Frenos's answer: a free, bounded, one-day on-ramp that gives critical infrastructure operators evidence they can defend in front of a board, a regulator, or an insurer.

The platform's scale is on the record. At the , Frenos completed 154,000 OT attack path simulations in 17 minutes and 7 seconds, validating 18 attack paths from assumed-breach networks into the critical Rockwell and Siemens zone. .

"We started Frenos as a team of former OT security practitioners," said Brian Proctor, Co-Founder & CEO of Frenos.

"We built the platform we wish we'd had back when we were the ones securing these environments. Mythos and the frontier models are going to surface zero days at a cadence defenders have never seen. When zero days arrive in waves, perimeter security stops being a strategy. You have to assume breach and run attack path analysis to strengthen internal defenses immediately. We're offering this for free because the OT security community cannot wait a budget cycle to find out where they are most vulnerable and what to do about it."

Finally Conduct OT Penetration Tests Without Harm to Production

The Mythos Readiness OT Assessment is a free, one-day, fixed-scope, onsite or remote engagement that delivers:

• A consequence-free digital twin built from existing networking configuration and security data.
• No scanning, no agents, no software, no hardware, no touching OT production systems.
• Hundreds of millions of adversarial simulations per second run against the cyber digital twin, to identify the most probable attack paths and adversary TTPs.
• A ranked list of viable attack paths with attack step TTPs and recommended mitigations.
• A Mythos Readiness Scorecard for board, audit, and regulator review.
• A live review and working session with Frenos' Chief Hacking Officer Collin Murphy.

"Customers don't leave with another vulnerability or list of action items," added Brian Proctor. "They leave with the specific attack paths an AI-era adversary would chain together against their environment, ranked by feasibility and impact, with the highest-leverage mitigations called out."

Frenos will explore the impacts Mythos has in OT security in its May 11 webinar, "Blind to the Blast Radius: Why the AI Era's Biggest Risk Is the Infrastructure Powering It," featuring Dragos CEO Rob Lee and former NSA Director of Cybersecurity Rob Joyce.

About Frenos

Frenos is the industry's first fully simulated AI penetration testing platform, combining digital twin technology with an AI reasoning agent that thinks like an adversary to reveal every attack path in your OT environment, risk-free. Frenos transforms how operational technology (OT) cybersecurity teams assess the cybersecurity posture of mission-critical sites and environments, reducing assessment time from months to minutes with zero impact on operations.
