Close exposures across your converged IT/OT environments
Get comprehensive IT and OT visibility so you can understand and defend your entire attack surface.
Protect industrial operations and critical infrastructure
Close exposures created by accidental IT/OT convergence to stop attacks and prevent damage in your IT/OT operations.
Get enterprise-wide visibility for your IT/OT environments
Whether your organization is a small one site location or has hundreds of sites across a complex and distributed environment, stopping an attack requires the ability to see it. In the past, siloed IT and OT security practices resulted in significant blind spots, thus limiting your ability to detect vulnerabilities and prevent attacks. Tenable OT Security with Tenable Nessus eliminates blind spots and gives you a holistic view of your cyber risk with both IT and OT domain expertise in a single solution. With Tenable OT Security you can comprehensively identify potential risks and address security threats sooner.
Tenable OT Security supports more than 90% of PLC products on the market today and has full integration with the Tenable product portfolio. To leverage your existing IT security investments, Tenable OT Security also integrates with industry-leading enterprise IT security products. The result is a comprehensive security solution that leverages all security products and provides unprecedented IT and OT visibility so you can understand and defend your entire attack surface.

Threat detection and mitigation
Proactively find weak spots in your OT environment by identifying areas where threat actors may launch attacks or take advantage of security weaknesses. Find more threats by leveraging a combination of powerful network and device-based threat detection engines, which alert to potential incidents coming from IT or OT, external and internal sources — whether human, ransomware or malware-based.
Tenable OT Security identifies anomalous network behavior, enforces network security policies and signatures and tracks local changes on devices so your organization can detect and mitigate risky events in your industrial control system (ICS) environments.
Fine-tuning policies, anomalies and signatures enables you to customize the security and alarms that are optimal for your operation. Context-aware alerts and detailed information give you the intelligence you need to meaningfully respond to threats based on full knowledge and details into what happened.

Asset tracking
Tenable OT Security’s automated asset discovery and visualization capabilities provide a comprehensive, up-to-date inventory of all assets, including workstations, servers, human machine interfaces (HMIs), historians, programmable logic controllers (PLCs), remote terminal units (RTUs), intelligent electronic devices (IEDs) and network devices.
Tenable’s patented active querying capabilities discover dormant devices that do not communicate over your network. The inventory contains unparalleled asset information depth - tracking firmware and OS versions, internal configurations, patch levels and users, as well as serial numbers and backplane configuration for both IT and OT assets.
Pinpoint vulnerabilities
Proactively identify and remediate vulnerabilities before attackers exploit them. Drawing on comprehensive and detailed asset tracking capabilities, Tenable OT Security uses a Vulnerability Priority Rating (VPR) that generates a score and a triaged list of relevant threats. This is based on the specific equipment in your environment, as well as parameters such as firmware versions, relevant CVEs, proprietary Tenable research, default passwords, open ports, installed hotfixes and more. Reports include detailed insights, along with mitigation suggestions.

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 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.
Leverage tenable’s “ecosystem of trust”
Leverage your existing security investments. Tenable OT Security fully integrates with Tenable Security Center and Tenable Vulnerability Management for full visibility, security and control across your converged operations. Tenable OT Security works in conjunction with Tenable Identity Exposure to identify Active Directory (AD) misconfigurations and threats that can result in ransomware attacks in OT environments. Tenable OT Security also has full integration with IT security technologies you already use such as IT service management, next-generation firewalls (NGFW) and security information and event management (SIEM) vendors.
With integration and collaboration across the Tenable product line, as well as leading IT and OT security systems, you’ll gain full situational awareness needed to secure operations from today's IT and OT threats.
