Your operations deserve protection that never stops
Prevention-first OT security across 3,600+ deployments, engineered for zero operational disruption.
OT Security AssessmentSenninRecon
Security improvement that can actually be done. SenninRecon is the assessment entry point for TXOne Sennin. It runs passive, zero-touch discovery across your OT environment, scores the vulnerabilities that pose real risk to production, and delivers a recommendation set that respects patch windows, change management, and the realities of running a plant. It is the lowest-commitment way to start an OT security program, and the highest-evidence path into one.
Most OT Assessments End in a Binder. SenninRecon Ends in Action.
Every OT site has been assessed. Most have been assessed several times. The problem has never been the lack of an assessment. The problem has been the gap between recognizing the need for OT security and actually being able to do something about it. SenninRecon was built to close that gap. It produces findings scored by real-world risk, recommendations safe to deploy in production, and an assessment methodology that is repeatable enough to use across an entire enterprise or an MSSP’s customer base.
- Passive, zero-touch discovery of OT assets at the network level (Level 3 visibility).
- Production-safe recommendations that factor in patch windows and change management by design.
- Standardized methodology. Repeatable across sites, regions, and MSSP engagements.
- Pairs with Stellar Discover for endpoint-level (Level 1/2) visibility, completing the Discover phase of the DAP framework.
VSAR: Vulnerability Scoring That Reflects How Threats Actually Behave
CVSS scores tell you what could go wrong in theory. SenninRecon’s VSAR (Vulnerability Situational Awareness Rating) tells you what is actually being exploited, where, against whom, and whether your operation is in the line of fire.
-
Multi-Source Risk Inputs
VSAR combines CVSS, EPSS, and TXOne’s own real-world attack telemetry and threat research intelligence. Vulnerabilities are scored based on how they are actually being exploited in the wild.
-
Virtual-Patching Identification
VSAR explicitly flags vulnerabilities that can be mitigated with IPS patterns instead of software patches, opening up production-safe remediation paths for systems that cannot be touched.
-
IEC 62443 Alignment
Findings and recommendations map cleanly to IEC 62443 control objectives, so assessment outputs feed directly into compliance reporting.
-
Production-Safe by Design
Recommendations are reviewed against patch windows, change-control reality, and operational constraints. Nothing in the report asks the operator to do something the operator cannot do.
From Discovery to Decision: the SenninRecon Assessment Workflow
SenninRecon is a workflow, not a one-time scan. It is engineered to be run, reviewed, and re-run as part of an ongoing OT security improvement program.
-
Passive Asset Discovery
Zero-touch network-level discovery identifies OT assets without risky active probing: no agents, no port scans, no protocol risk.
-
VSAR-Prioritized Findings
Each identified asset is associated with the vulnerabilities that are most likely to be exploited against it, scored with VSAR, and tied to suggested mitigations.
-
Evidence-Based Reports
Reports are designed for budget justification, not binder-padding. Data backs every finding; every recommendation is paired with the operational guardrails it must respect.
Built for the People Who Have to Carry the Findings
SenninRecon is purpose-built for the security planners, consultants, and MSSPs who turn assessments into programs, and for the operations teams who have to live with the recommendations.
-
Security Planners
A standardized methodology for sites, divisions, and the enterprise. Repeatable assessments mean trend analysis, not one-off snapshots.
-
Consultants & MSSPs
A repeatable assessment practice with evidence-based outputs that justify budget, defend recommendations, and shorten the time from engagement to renewal.
-
Operations Leaders
Recommendations that are safe to deploy, scoped to the realities of the line, and clearly tied to the assets that produce business value.
Better Together: SenninRecon, SenninOne, and Stellar Discover.
SenninRecon is engineered as the entry point and plugs directly into the rest of the TXOne Complete portfolio.
- Combine SenninRecon with Stellar Discover to cover both network-level (Level 3) and endpoint-level (Level 1/2) visibility, completing the Discover phase of the DAP framework in a single bundle.
- Promote findings into SenninOne, our enterprise orchestration platform, for asset-centric investigation, MITRE ATT&CK for ICS-mapped triage, and one-day vulnerability ticketing.
The result is an assessment that does not stop at the report. It becomes the front door to a measurable, sustainable OT security program.
