Why choose Tenable OT Security?

Access market-leading OT vulnerability management capabilities,
purpose-built to help secure your operations

Complete visibility

Get a comprehensive view of your environment. Go deeper than simply listening to network traffic by actively querying devices in their native protocols.

Proactive risk-based insights into vulnerabilities

With real time information about your network and devices, you'll always know your risk profile and be ready to address new threats as they emerge.

Unified OT and IT Security

For complete understanding of your modern attack surface, unify your OT and IT cyber security with a single vendor in an integrated solution.

Get complete visibility across your entire attack surface

Manage all assets

Aggregate information from all sites to manage assets across your entire OT infrastructure in a single dashboard. To proactively comply with security and compliance regulations, pull paper documents and audit reports at any time.

Proactively address vulnerabilities

Routine controller queries provide details about firmware versions, open ports, hardware configuration, installed patch levels and more to give you visibility into vulnerabilities that may impact your industrial controllers.

Control policies

Centrally set or change a policy once and automatically push it across your enterprise. You can also selectively deploy a policy based on any criteria.

Forensics support

Improve awareness with enterprise-wide visibility, along with full drill-down capabilities for any asset or event, including important details and meaningful alerts to improve your situational awareness and forensic support.

Snapshot changes

Compare current device snapshots with previous snapshots to get a better understanding of network changes, including insight into what happened when changes occurred. You can even roll a device back to its last-known good state.

Key features

Hyrbid threat detection and asset discovery

Get unmatched visibility and security across IT, OT, and IoT environments with advanced network detection and proactive monitoring capabilities. Tenable OT Security uses deep-packet inspection and ICS/SCADA Smart Scanning to monitor critical activities and detect anomalies in real time, while Active Query technology safely examines device data without impacting operations. This integrated approach detects and helps manage and mitigate risks efficiently.

Cyber threat detection and mitigation

With its multi-detection engine, Tenable OT Security identifies policy violations, detects anomalous behaviors, and tracks signatures for potential high-risk events. It then sends context-aware alerts with detailed information to your team so you can quickly respond and launch forensic investigations into what happened.

Risk-based it/ot vulnerability management

Drawing on comprehensive and detailed IT and OT scanning capabilities, Tenable OT Security generates vulnerability and risk levels using Predictive Prioritization for each asset in your ICS network. Reports include risk-scoring and detailed insights, complete with mitigation suggestions. This enables security teams to quickly identify and prioritize the most critical cyber risks for remediation before vulnerabilities can be exploited.

Configuration control

With Tenable OT Security, you can track malware and user-executed changes made over your network or directly on a device. Tenable OT Security provides a full history of device configuration changes over time, including the granularity of specific ladder logic segments, diagnostic buffers, tag tables, and more. This enables administrators to establish a backup snapshot with the "last known good state" for faster recovery and compliance with industry regulations.

Complete visibility

Attacks can easily propagate in a converging IT/OT infrastructure. With a single platform to manage and measure cyber risk across your OT and IT systems, you have complete visibility into your converged attack surface. Tenable OT Security also natively integrates with leading IT security and operational tools, such as your Security Information and Event Management (SIEM) solution, log management tools, next-generation firewalls, and ticketing systems.

Enterprise-grade management with tenable ot security

Tenable OT Security is engineered for scalability across multi-site and distributed environments, offering centralized control for enhanced security and vulnerability management. This robust platform ensures uniform security protocols and comprehensive reporting capabilities are applied consistently, no matter the geographical spread of your operations, making it ideal for enterprise-wide deployment.

“In the past, asset management was labor intensive and time-consuming, and although we have design documents, asset and vulnerability management for security was mainly manual tasks. Recently, threat information has increased further, and in order to respond quickly, we decided that we should deploy new solutions and proceed efficiently in light of threats and other factors.”

With Tenable tuned and trained to prevent false positives, we’ve reduced the number of reported events by 98% – a tremendous time savings. What used to take two days per week to manage now takes only a few hours, and we’ve improved efficiency by 87%.
