Tenable strengthens coverage for operational technology and industrial control systems


Tenable, the Exposure Management company, announced new capabilities within Tenable OT Security, providing broader protection for operational technology (OT), critical infrastructure and industrial control systems, regardless of size of deployment or configuration of environment

The new functionality keeps the CISO’s organisation front and centre — making it even easier to secure and maintain governance of the entire attack surface, using the same tools and processes across their infrastructure, be it OT, IT, IoT, cloud or other platforms. 

Tenable is positioned to help its clients meet their security requirements, offering a comprehensive solution for securing mixed environments. This latest update extends Tenable OT Security’s vulnerability detection capabilities even further with the upgrade to the OT active scanner and an even tighter integration with Nessus, Tenable’s vulnerability scanning technology. Tenable OT Security now offers customers unprecedented scanning capabilities using the technology trusted by more than 40,000 security teams worldwide.

Key new capabilities include: 

Increased Asset Discovery and Visibility: 

○ Extended Active Query capabilities at the sensor layer to allow for deep asset visibility across network segments 

○ Upgraded management experience for Tenable OT Security sensors

○ Added support for an extensive list of controllers, including Bosch PSI Controllers, Bachmann M1 and many more, greatly expanding Tenable’s asset discoverability capabilities

Advanced Vulnerability and Threat Detection: 

○ Augmented scanning capabilities through seamless integration with Nessus, giving users the option to fully leverage Nessus’ smart scanning against confirmed IT devices, safely, without affecting productivity

○ Dashboard widgets to Nessus’ plugin-based vulnerability detection for easy viewing of vulnerability data

○ Improved Intrusion Detection System (IDS) Engine feed that can now be continuously updated on demand via cloud or offline 

Enhanced Dashboards and Reporting: 

○ Enhanced Enterprise Management Dashboards that now provide a centralised view of multiple connected operational sites, enabling quick and easy exporting of reports to share with business and operations stakeholders

○ Dozens of user-configurable widgets that highlight common and most severe vulnerabilities, common policies and common plugin families 

○ Upgraded UI experience with the option of dark mode for comfortable viewing in low light environments

“We consistently hear from CISOs that they have been tasked with security for mixed environments that include both OT and IT technologies, but they don’t have the requisite visibility to secure either well. The new capabilities added to Tenable OT Security provide our customers with full visibility, security and control of all their environments and assets, in one consolidated view,” explained Amir Hirsh, general manager, OT Security, Tenable. “Now, our customers can leverage the full strength of Tenable OT active scanning, tightly integrated with embedded Nessus scans for IT assets, to create a clear view of all assets, their vulnerabilities, risk score, attack path analysis and more.”

This latest update also features product localisation capabilities including Chinese, Japanese, French and German language, helping to reduce training and support costs for companies operating in non-English speaking regions.
