The operational technology in your factory floor isn’t built to run traditional IT or security software. Attempt it and your assets and productivity will come to a screeching halt. Tenable OT Security was purposely built to run safely on OT environments, from modern devices to legacy systems, without disruption. Its vulnerability and threat detection capabilities also help you eliminate unplanned downtime by preventing security incidents that could have otherwise affected the productivity of your manufacturing operations.

With the advent of digitization, IT devices can make up half of the modern manufacturing environment. Tenable OT Security passively monitors networks to discover both IT and OT devices and once assets have been classified, it runs Tenable Nessus® to scan IT devices and Active Query to communicate with OT devices using native protocols. It then aggregates all this information in a centralized location to give you a complete inventory of all assets, to comprehensively monitor, manage, and secure your entire infrastructure.

Leverage the industry's most comprehensive vulnerability coverage to identify potential entry points and weak links in your IT and OT environments, where cyber attackers can attempt to gain unauthorized access or exploit vulnerabilities. With built-in vulnerability scoring and prioritization, threat intelligence and real-time mitigation insights, Tenable OT Security helps you understand your exposures and proactively prioritize vulnerabilities. 

Tenable OT Security continuously monitors for threats and anomalous activity, leveraging multiple detection methodologies and alerting on threats coming from external and internal sources. It also identifies security issues on dormant devices that do not communicate over the network by performing device-based threat detection, enabling organizations to mitigate risky events in OT environments. Alerts include detailed information that can accelerate incident response and be used as audit trail in forensic investigations.

Keep track of all device configurations and get alerts when changes are executed by a user or by malware ― whether over the network or directly on the device. With Tenable OT Security, you get a granular view of all configuration changes made to a device over time, including specific ladder logic segments, diagnostic buffers, tag tables and much more. If changes are unauthorized or happened inadvertently, you can revert a device to its last-known good state to keep its intended operation and maintain compliance with industry regulations.
