Successful segmentation enhances security and understanding

Pros

"The clear distinction between IT and OT that Tenable OT provides is its most valuable feature."

Cons

"As an IT security professional, I would like to see automation improvements in the response part of Tenable OT Security."

What is our primary use case?

I went to a client to deploy Tenable OT based on their mixed network infrastructure, which was not segmented correctly. By deploying Tenable OT, I helped with the segmentation process, ensuring that OT environments such as HVAC systems, camera systems, and industrial control systems are segregated and secured.

What is most valuable?

The clear distinction between IT and OT that Tenable OT provides is its most valuable feature. The user interface clearly differentiates between vulnerabilities and action items from IT environments, making it easier to explain these differences to customers.

Helps identify vulnerabilities and risks for IT and OT assets

Pros

"I like Tenable OT Security for two main reasons. Firstly, it helps identify vulnerabilities and risks for IT and OT assets, which is crucial for our operations. Secondly, it performs external port scanning, including vulnerability scans for open ports. Compared to the Claroty Platform, the tool offers detailed asset discovery capabilities. "

Cons

"Tenable OT Security is fine, but I find it more language-based rather than structured. It feels like something is on a web page, and the dashboards and data representations are not cool. First of all, I said that the tool view should be improved. It looks pretty old. Second, the details Tenable OT Security provides regarding the metadata they work with should be more in-depth. Its main focus is vulnerability management, which is fine, but what about threat actors? What about attack vectors and OT vulnerabilities? There are major areas, baselines, etc. that need attention. "
