Endpoint Excellence
Discover. Assess. Protect. Operations-First Endpoint Security

TXOne Stellar gives every OT endpoint the same level of protection. Prevent threats from running in the first place, without disrupting the production line.

Why Traditional Endpoint Security Fails on the Plant Floor

Traditional endpoint security was built for office laptops, not for industrial control systems. Constant signature updates require always-on internet connectivity. Intrusive scans tax processors running at capacity. Aggressive responses can quarantine a process that the line depends on. A single false positive can take a shift down. In OT, security that disrupts operations has failed twice: once for the security team and once for the people running the plant.

Stellar takes a different path. It treats the operation as the priority and builds security around it.

Stellar comprises two purpose-built OT security agents: visibility-first and prevention-focused. Together, they cover every endpoint in the operation, and they upgrade in place when you are ready.

Stellar Discover (NEW)

Safe OT endpoint visibility, without disrupting operations.

A user-space sensor that maps your full OT endpoint inventory and vulnerability surface without kernel drivers, reboots, or conflicts with your existing IT EPP/EDR.



Best for: Sites that need OT endpoint visibility before, or alongside, a prevention rollout.



Stellar Protect

Operations-first endpoint protection for ICS.


A prevention agent that combines an industrial application repository, per-device behavioral baselines, and multi-method threat scanning to block threats before they execute.



Best for: Sites that need to lock down ICS endpoints, HMIs, kiosks, and Linux servers without disrupting operations.


See Every OT Endpoint. Disrupt Nothing.

Stellar Discover is a detection-only sensor designed to be safe enough for even the most cautious OT operator. It runs entirely in user space, installs in about a minute, and never touches the kernel.
  • Zero kernel access, zero reboot. Architecturally incapable of causing the kind of stability issue that has eroded trust in agent-based tools.
  • Co-exists with IT EPP/EDR by design. Adds OT-specific endpoint context next to CrowdStrike, Defender, SentinelOne, without conflict.
  • Complete OT endpoint context. Device and software inventory, vulnerability detection, USB activity, login failures, network flows, and active malware reporting (log only).
  • Scheduled/On-Demand Malware Scan: Identify how many devices are infected with malware and continue monitoring to see if the infection worsens.
  • One-click remote upgrade to Stellar Protect. When the time comes for prevention, no reinstallation, no site visit, no production disruption.

Prevent Threats Before They Run

Stellar Protect is the prevention agent for industrial endpoints. It combines an industrial application repository, per-device behavioral baselines, and multi-method scans to stop threats before they impact the operation, including fileless and living-off-the-land techniques.
  • Built for long lifecycles. Supports Windows 2000 SP4 through Windows 11 / Server 2025, plus Linux, Ubuntu, RHEL, CentOS, Rocky, and Debian, with support committed through at least 2031.
  • CPSDR behavioral prevention. Per-device fingerprints catch unexpected changes, including malware, unauthorized access, accidental misconfigurations, and malicious process modifications, and block them before they execute.
  • 70,000+ OT applications and certificates are maintained in partnership with leading device makers. Making trust lists is automated, not a manual project.
  • Two editions, one agent platform. ICS Edition for the full prevention suite on standard ICS endpoints and Linux servers; Kiosk Edition for constrained single-purpose systems and the oldest legacy endpoints.
  • Operationally safe response. When prevention fires, response actions are moderated by operational context, not flat IT-style quarantines.

This is what the Discover. Assess. Protect. framework looks like at the endpoint.
Visibility leads to prioritization. Prioritization leads to prevention.
Every step is designed to keep the operation running.

Discover

Stellar Discover sensors deploy in minutes and inventory every OT endpoint, including software, vulnerabilities, malware scans, USB activity, and network flows.

Assess

Telemetry from Stellar Discover and Stellar Protect feeds SenninOne enterprise governance, which prioritizes vulnerabilities by real-world risk and recommends production-safe actions.

Protect

A one-click remote upgrade turns Stellar Discover sensors into Stellar Protect agents, applying CPSDR prevention without reinstallation or downtime.

CPSDR: Prevention That Understands Your Operation

Cyber-Physical Systems Detection and Response (CPSDR) is the prevention engine inside Stellar Protect. Instead of waiting for a threat to be identified before responding, CPSDR fingerprints the expected behavior of each managed endpoint and prevents anything outside that fingerprint from running. New fileless and living-off-the-land techniques are blocked before execution. Any behavior outside the approved baseline is denied, regardless of whether a signature exists.
