See Every OT Asset. Score Every Risk in Operational Context.
Your security program cannot protect what it cannot see, and cannot prioritize what it cannot score. TXOne SenninRecon discovers every OT asset and scores every vulnerability in operational context, without touching production.
Discovery and Assessment
Most OT security programs begin with an honest admission: we do not know what we have, and we do not know what is at risk. SenninRecon answers both questions without touching your production systems.
Traditional vulnerability scanners are dangerous in OT, and traditional asset inventory spreadsheets are already out of date the moment they are saved. TXOne SenninRecon delivers automated OT asset discovery and risk scoring through a hardware appliance that deploys in hours without interrupting operations. VSAR scores vulnerability severity using CVSS, EPSS, real-world attack telemetry, and TXOne threat intelligence. SenninRecon then layers operational context so a critical CVE on an air-gapped system with virtual patch coverage ranks lower than a moderate CVE on a network-facing asset. If you have already invested in a network visibility platform, SenninRecon adds the asset-level assessment and operational-context scoring that closes the enforcement gap between visibility and action. Assessment reports include IEC 62443-3-3 gap analysis so your next security review starts with evidence, not estimates.
Why Discovery and Assessment Stall in OT
OT teams face discovery and assessment challenges that IT-adapted tools create more than they solve.
01 / 04
Your Asset Inventory Is Out of Date Before the Next Audit
Manual spreadsheets and periodic walk-downs cannot keep pace with equipment changes, vendor swaps, and contractor work. Your compliance auditor arrives and the inventory you are required to maintain is already incorrect. You cannot protect assets you cannot name, and you cannot plan security investments you cannot size.

Discovery and Assessment Framework
Three capabilities that turn unknown OT into prioritized action
01 / 03
Automated OT Asset Discovery
SenninRecon discovers assets across your OT environment through passive network listening combined with optional safe queries. No active vulnerability scans. No traffic storms. No risk to PLCs and safety systems.

What SenninRecon Delivers
TXOne SenninRecon is the hardware appliance that turns OT unknowns into a prioritized action plan, without the risks traditional discovery and assessment tools create.
01 / 05
Passive Discovery That OT Teams Accept
Your operations team has seen active scanners crash production before. SenninRecon discovers assets through passive network listening, with optional safe queries only where explicitly approved. No traffic storms. No controller lockups. No production risk. The appliance deploys in hours and begins building your asset picture inside your next maintenance window.
