Every Endpoint Protected. No Production Disrupted.
Endpoint Protection
Your legacy Windows systems power critical production, but IT security vendors abandoned them years ago. Your most vulnerable assets are the ones they refuse to protect. TXOne Stellar covers Windows 2000 through Windows 11 with one-minute visibility and zero-disruption prevention, without touching the systems your operations depend on.
IT-adapted EDR solutions crash legacy systems, generate false positives on legitimate OT processes, and demand resources constrained endpoints cannot provide. TXOne Stellar delivers endpoint security designed for OT realities in two editions. Stellar Discover installs in one minute with no drivers and no kernel access, giving your security team device-level visibility that co-exists with any IT EDR already running. Stellar Protect delivers full prevention across Windows 2000 through Windows 11 with automated per-device baselines, 70,000+ OT applications recognized automatically, and Cyber-Physical Systems Detection and Response (CPSDR) that blocks unauthorized changes before they impact production. If you have already invested in IT endpoint security, Stellar adds the OT coverage IT EDR was never built to deliver. StellarOne forwards telemetry to Splunk, Microsoft Sentinel, and QRadar, and maps to IEC 62443 and NIST CSF requirements.
Legacy System Security Challenges
Industrial endpoints running legacy systems face cybersecurity challenges that traditional IT security solutions were never designed to address.

Unsupported Systems, Unprotected Operations
Windows XP, Windows 7, and Server 2008 remain essential to production, yet IT security vendors abandoned support years ago. Your most critical and legacy assets run without protection because upgrading means replacing millions in functional equipment.

01 / 03
Visibility-First Deployment
Stellar Discover installs in one minute per endpoint with no drivers, no kernel access, and no reboot. Runs entirely in user space, at the same privilege level as Windows Notepad, so it cannot destabilize the systems it monitors. Co-exists with any IT EDR already deployed.

CPSDR Technology
Cyber-Physical Systems Detection and Response fingerprints each endpoint and blocks unauthorized changes the moment they occur, before they impact operations. Prevention happens before execution. No waiting on detection, analysis, or signature updates.
