Your operations deserve protection that never stops
Prevention-first OT security across 3,600+ deployments, engineered for zero operational disruption.
Endpoint ExcellenceStellar Discover
Safe OT endpoint visibility, without disrupting operations. Stellar Discover is a detection-only sensor that runs entirely in user space, with no kernel access, and no system interference. It deploys in about a minute, requires no reboot, and co-exists with the IT EPP/EDR you may already run. A complete picture of every OT endpoint that even the most cautious operator will say yes to.
OT Endpoint Visibility Without the Trust Tax
For years, OT teams have had to choose between two bad options: Install a kernel-level agent and risk an event that takes the line down or stay blind and let asset inventories drift further and further from reality.Stellar Discover removes the trade-off. Its user-space sensor is architecturally incapable of causing the kind of stability issue that has eroded trust in agent-based tools. It still delivers the OT-specific endpoint context your security and operations teams need to make better decisions.
-
Zero Kernel Access
Operates at guest privilege level, as safe as Windows Notepad.
-
One-minute Install
No reboot, no driver, no configuration.
-
Co-exists with IT EPP/EDR
No conflict with CrowdStrike, Defender, SentinelOne, or any other endpoint stack you already run.
-
Operates as Designed in Active Production Environments
No system interference at runtime.
A Complete Picture of Every OT Endpoint
Stellar Discover extends visibility to the device level, collecting endpoint context to offer a comprehensive security overview.
-
Device & Software Inventory
Hardware, OS, network flow records, and full software inventory across every managed asset.
-
Scheduled/On-Demand Malware Scan
Identify how many devices are infected with malware and continue monitoring to see if the infection worsens.
-
Vulnerability Detection
Data feeds directly into SenninOne, where it is prioritized using VSAR (Vulnerability Situational Awareness Rating) for production-aware decisions.
-
USB & Login Activity Monitoring
Tracks USB insertion records and login failures, two of the most telling early indicators of compromise on the plant floor.
Designed to Co-Exist With What You Already Have
Stellar Discover is built to exist alongside the security tools you have already standardized on. It does not compete with IT EPP/EDR; it adds the OT-specific endpoint context that those tools cannot provide. The user-space architecture means there are no kernel hooks to fight over, no driver conflicts, no scheduling collisions. The result is endpoint visibility that the security team can validate and that the operations team can approve.

Illuminates OT Endpoint Blind Spots
Illuminates the OT endpoint blind spots alongside IT EPP/EDR.
-
No Prevention, No Quarantine, No Kernel Hooks
Discover is a sensor, by design.
-
Telemetry Feeds StellarOne
Telemetry feeds StellarOne for VSAR-prioritized vulnerability management at enterprise scale.
-
Centrally Managed
Centrally managed through the StellarOne console.
Reports You Can Hand to Leadership
Stellar Discover ships with a scheduled assessment report that turns telemetry into a board-ready summary out of the box. Each report includes an executive summary, an asset health overview, a vulnerability severity breakdown, active malware reporting, USB and login activity trends, and a set of actionable recommendations, each tied to specific assets the team can act on.
-
Executive Summary Suitable for Leadership Review
-
Asset Health Overview by Site and by Line
-
Vulnerability Severity Breakdown Using VSAR-Aligned Scoring
-
Active Malware Reporting and USB / Login Trend Analysis
-
Asset-Specific Actionable Recommendations
One Click From Visibility to Prevention
When your program is ready to move from Discover to Protect, Stellar Discover sensors can be upgraded to Stellar Protect agents with a single click in the StellarOne console. There is no reinstallation. There is no site visit. There is no production disruption. Better still, the deployed sensor count becomes the per-seat ICS quote basis, so the data you have already collected drives the deployment sizing for the prevention rollout.

No Reinstallation, No Reboot, and No Site Visit
