Your operations team remembers what previous endpoint agents did to production. Stellar Discover is different.

Every OT operations team has a story about the security tool that caused a production outage. Kernel drivers conflicted with the HMI software. The HMI crashed. Production stopped. Afterward, the answer to every endpoint security request was: no. Stellar Discover was designed around the opposite assumption. It runs entirely in user space, at the same privilege level as Windows Notepad. No kernel access. No drivers. No reboots. Install in one minute and begin surfacing software inventory, per-endpoint vulnerability telemetry feeding SenninOne's VSAR scoring, USB activity monitoring, login failure tracking, and active malware reports. Co-exists with any IT EDR already deployed, so your security team can add OT-specific visibility without rip-and-replace. Fixed price, unlimited sensors, 6-month term. When the assessment shows which endpoints need protection, StellarOne handles the one-click remote upgrade to Stellar Protect.

The Agent That Cannot Crash Your System

Every OT operations team has a story about the security tool that caused a production outage. Stellar Discover was designed so that story never happens again. It runs entirely in user space, architecturally incapable of affecting system stability the way kernel-level agents can. Install in one minute per endpoint. Co-exist with any IT EDR already deployed. See software inventory, vulnerability telemetry, USB activity, login failures, and active malware on the endpoints that previously rejected agents. When the assessment shows which endpoints need full protection, StellarOne upgrades Discover sensors to Stellar Protect agents with one click. Fixed price, unlimited sensors, six-month term: licensing that lets you deploy everywhere first and negotiate protection with evidence.

Challenges

OT Security Challenges

Critical challenges that Stellar Discover is purpose-built to solve

01 / 04

Your most vulnerable assets are your biggest visibility blind spots

OT Endpoints Are a Visibility Gap in Your Security Program

Your IT EDR cannot tell you what software is installed on a Windows XP HMI, whether USB devices are connected after hours, or which endpoints have active malware your network tools missed. Only 6% of organizations have full detection coverage at Purdue Level 0/1.

01 / 06

User-Space Architecture with Zero Kernel Access

Stellar Discover runs entirely in user space. No kernel drivers, no kernel access, no deep system hooks. It operates at the same privilege level as Windows Notepad and is architecturally incapable of interfering with system operations. The OT Leader objection to endpoint agents dissolves because Discover cannot affect system stability by design.

Key Capabilities

No kernel drivers installed

No reboot required for install or updates

User-space privilege equivalent to Notepad

Co-exists with existing IT EPP/EDR by design

One-Minute Install with No Configuration

Deploy Stellar Discover sensors in one minute. No reboot, no configuration, no site visit. Central activation through StellarOne. Sensors begin collecting telemetry immediately across Windows endpoints that traditional agents cannot safely touch.

Key Capabilities

One-minute install per endpoint

No reboot and no configuration required

Central activation through StellarOne

Immediate telemetry collection on deployment

C

Co-Existence with IT EPP and EDR

Stellar Discover is designed to co-exist with CrowdStrike, Microsoft Defender, SentinelOne, and other IT endpoint tools. No conflicts, no mutual interference. Where IT EDR protects against threats, Discover surfaces OT-specific telemetry those tools were never designed to capture.

Key Capabilities

Designed for co-existence, not replacement

No driver conflicts with IT EPP or EDR

Fills OT visibility gaps IT tools cannot address

Expands coverage without disrupting existing investments

OT-Specific Endpoint Telemetry

Discover collects device inventory, software inventory, per-endpoint vulnerability data, USB activity, login failure tracking, network flow records, and active malware reporting (log only). Network tools show traffic; Discover shows what is running inside each endpoint. Only 6% of organizations have full detection coverage at Purdue Level 0/1 (SANS 2025).

Key Capabilities

Software and vulnerability inventory per endpoint

USB activity and login failure tracking

Network flow records from the endpoint perspective

Active malware reporting (log only, no prevention)

Fixed-Price Licensing for Unlimited Sensors

Stellar Discover is priced at a fixed amount for unlimited sensor deployment over six months. No per-seat counting, no procurement friction, no deployment-size penalty. Deploy as broadly as your environment requires. The assessment report becomes the evidence for any future prevention investment.

Key Capabilities

Fixed price for unlimited sensor seats

Six-month license term

No procurement friction on deployment scale

Assessment report as investment evidence

O

One-Click Remote Upgrade to Protect

When the assessment report identifies endpoints requiring active prevention, upgrade Discover sensors to Stellar Protect agents with one click via StellarOne. No reinstallation, no site visit, no production disruption. Deployed sensor count directly informs per-seat ICS license sizing for accurate procurement.

Key Capabilities

Remote activation of prevention on existing sensors

No reinstallation or site visit required

Sensor telemetry informs accurate ICS license sizing

Staged visibility-to-prevention maturity path

User-Space Architecture with Zero Kernel Access

Stellar Discover runs entirely in user space. No kernel drivers, no kernel access, no deep system hooks. It operates at the same privilege level as Windows Notepad and is architecturally incapable of interfering with system operations. The OT Leader objection to endpoint agents dissolves because Discover cannot affect system stability by design.

Key Capabilities

No kernel drivers installed

No reboot required for install or updates

User-space privilege equivalent to Notepad

01 / 05

Start OT Endpoint Security with Visibility First

For organizations early in OT security maturity, Stellar Discover delivers device-level visibility without the operational risk of prevention-first tools. See asset inventory, software installed, vulnerabilities present, and USB behavior. Build the evidence base before deciding where prevention belongs.

Generate Evidence-Based Prevention Investment Cases

Use the Stellar Discover assessment report to identify endpoints with active malware, critical vulnerabilities, or risky USB behavior. When the assessment shows active malware on 9% of endpoints, the conversation shifts from should we deploy endpoint security to which endpoints need protection first. Upgrade prioritized sensors to Stellar Protect with one click.

Fill Endpoint Gaps Network Visibility Tools Cannot See

Network detection platforms such as Nozomi, Claroty, or SenninRecon show traffic between endpoints. They cannot show what is running inside each endpoint. Stellar Discover adds device-level evidence: software inventory, per-endpoint vulnerabilities, USB activity, and login patterns. Only 6% of organizations have full detection coverage at Purdue Level 0/1 (SANS 2025).

User-Space Sensor Architecture

The Agent That Cannot Crash Your System

Traditional endpoint tools install kernel drivers because they need deep system access for real-time prevention. Kernel access means system interference risk. Discover runs entirely in user space, architecturally incapable of affecting system stability. It cannot stop threats because stopping threats requires kernel access, but it can see everything happening on OT endpoints for the first time.

No kernel drivers, no kernel access
User-space privilege equivalent to Notepad
Cannot cause system interference by design
Safe for HMI, SCADA, and engineering workstations

The only OT endpoint sensor architecturally incapable of affecting system stability.
