Frenos is a cybersecurity company focused on operational technology (OT) security. The company develops a simulated OT penetration testing platform that allows organizations to assess and improve their OT security posture without interacting with live production systems. Core platform capabilities include: - Digital Twin: A virtual replica of the customer's OT network used to safely run attack simulations - SAIRA (OT AI Agent): An AI reasoning agent that determines whether exploitable vulnerability conditions exist within an environment, accounting for environmental controls - Adversary Intelligence Engine: A community resource for OT-focused adversarial intelligence - Continuous OT Security Posture Management: Ongoing monitoring and assessment of security posture changes in near real time The platform enables organizations to run continuous adversary assessments, simulate attack paths at scale (demonstrated at 154,000 OT attack path simulations in 17 minutes), and prioritize vulnerabilities based on actual exploitability within their specific environment. Frenos also offers a professional services component called Optica, described as a rapid visibility service for OT security that enables analysis of critical infrastructure without requiring complete network visibility. The platform integrates with a range of third-party OT and IT security tools, including Claroty, Dragos, Nozomi Networks, Palo Alto Networks, Forescout, Tenable, Rapid7, Check Point, and Ember OT, among others. Target industries include electric utilities, oil and gas, manufacturing, healthcare, airports, maritime, rail, mining, pharmaceuticals, and smart cities.
