Digital Twin
On-Prem, Using the Most Advanced Technology
A high fidelity replica of your OT infrastructure, built from data you already collect. No new sensors. No scanning. You keep your data. 
The Most Accurate View of OT Risk, Ever
Execute safe, continuous OT penetration testing using the data you already have.
Three layers, one platform
Attack Path Analysis
AI-Native Adversary Simulation
The engine runs millions of adversary simulations against your digital twin. It maps every exploitable vector and ranks the routes that actually reach your crown jewels. 
SAIRA
Defensive Recommendations, Ranked
SAIRA, our AI reasoning agent, turns every simulation into prioritized, defensible action. Your team fixes what reduces the most risk and closes the most paths, fastest.
The Outcome
Know exactly where your defenses hold. And where they don't.
SAIRA, our AI reasoning agent, simulates real adversary tactics, techniques, and procedures against your environment. Attack Path Analysis proves every defense or exposes it.
Use Cases
Operationalized Intelligence
Network Path Validation
Truth versus assumption. Frenos ingests live firewall configs (Palo Alto, Cisco, Fortinet, Check Point) and routing tables, then validates whether your network boundaries actually hold.
Segmentation Analysis
Prioritized recommendations to tighten macro and micro segmentation. The foundation of CISA's OT zero-trust pillar.
Threat Actor Emulation
SAIRA fuses thousands of OSINT feeds to simulate active threat actors like VOLTZITE, Volt Typhoon, and Sandworm. It predicts campaign success against your environment.
Attack Path Analysis
Runs millions of simulations from assume breach footholds to validate attack chains terminating at the OT crown jewels you define, quantifying risk with your environments’ data rather than theoretical risk based upon industry datasets.
Vulnerability Reachability
Reachability and exploitability checks against findings from Tenable, Rapid7, or any vulnerability identification tool. Teams patch what is actually exploitable, not just what is listed.
Blast Radius
Quantify the downstream impact of compromise. See how segmentation weakness, trust relationships, and insecure ICS comms expand attacker reach across your operation.
Trending OT Security Posture
The only continuous OT assessment platform. Simulations auto-refresh as your environment changes.
Integration
Agnostic Data Ingestion
If you collect it, we use it. Frenos plugs into the OT and IT stack you already run. No rip and replace. No parallel collection layer.
