Find and inventory all your assets

Stop guessing what’s on your network. Build a complete inventory of OT, IoT, and IT assets. Use Safe Active Query to uncover deep device details, including firmware, backplane details, lifecycle data, and known vulnerabilities to eliminate blind spots.

Prioritize findings

Prioritize based on risk

Eliminate alert fatigue. Focus on critical vulnerabilities that actually threaten your production uptime and physical safety. Aggregate findings and deduplicate alerts based on real-world threat intelligence, exploitability, and specific business impact.

Detect threats

Detect changes and anomalies

Identify known and unknown threats with real-time configuration change and anomaly detection. Monitor digital and physical changes to ensure operational integrity and stop disruptions before they start.

Protect networks

Monitor risk across your networks

Visualize communication patterns and baseline asset behavior. Automatically identify boundary violations and enforce segmentation to prevent lateral movement across IT and OT.

Simplify compliance

Streamline and manage compliance

Eliminate the manual burden of compliance audits. Automatically map your security posture to relevant industry standards and compliance frameworks like NERC CIP, NIST, ISO 27001, PCI DSS, and IEC 62443 with out-of-the-box dashboards and executive reporting.

Communicate risk

Communicate OT risk insights

Clearly communicate cyber risk with advanced dashboards and reports, and seamless integration with Tenable Security Center. Access a unified view of your IT/OT security posture to track remediation metrics and effectively communicate risk with executive stakeholders, auditors, and insurance providers.

OT security FAQs

Find answers to common questions about Tenable One OT Exposure.

How does Tenable One OT Exposure discover assets without disrupting operations?

Tenable One OT Exposure uses a "do-no-harm" approach, combining passive network monitoring with patented, vendor-approved Safe Active Querying to communicate with devices in their native protocols.

Does Tenable support air-gapped environments?

Yes. Tenable offers flexible deployment models to meet specific security and cybersecurity compliance needs:

  • Cloud: For rapid scalability, continuous updates, and access to global threat intelligence from Tenable Research.
  • On-premises: For full local control, ideal for highly regulated or air-gapped OT networks.
  • Hybrid: A flexible combination that supports global, distributed operations with varying regional requirements.

What is the difference between VPR and standard CVSS scores?

CVSS measures theoretical severity, while Tenable’s Vulnerability Priority Rating (VPR) uses data science to measure real-world exploitability, helping you focus on the most dangerous threats first.

Can Tenable One OT Exposure scale to global operations and multi-site OT environments?

Yes. Tenable One scales with the complexity of global enterprises and distributed operational facilities. The Tenable cloud-native platform provides centralized visibility with local context to ensure consistent security policy and governance across all your plants, regions, and industrial networks.

What automated actions can Tenable One OT Exposure take in response to OT threats?

Tenable One integrates with your existing security and network infrastructure to enable automated, real-time threat response. Through these integrations, the Tenable exposure management platform can trigger actions such as:

  • Blocking malicious communications by updating firewall rules.
  • Opening a high-priority ticket in JIRA or ServiceNow with all relevant context.
  • Automatically initiating a specific workflow in your SOAR platform.

How does Tenable One discover unmanaged, unknown, or shadow OT assets?

Tenable One OT Exposure excels at finding every asset in your environment, including legacy, unmanaged, or rogue devices that other tools miss. Tenable One OT Exposure combines powerful discovery methods:
  • Continuous traffic monitoring by analyzing network traffic to see every device as it communicates.
  • Safe Active Queries using native industrial protocols to accurately identify and classify devices without disrupting sensitive processes.
  • File imports and interoperability that support the ability to manually import SCD and ACD files, CSV spreadsheet files, PLC project files, and other commonly used file formats to enrich your security data.
