Provides cost saving and offers device visibility
I think it's a stable solution and don't foresee any problems in the future. It's a leading security platform and is widely used in Italy. This gives them full visibility of all devices, which is often difficult to achieve. IT managers usually lack visibility into all products and security solutions. However, this platform lets customers gain visibility of their entire device environment. I rate its stability an eight out of ten.

Helps identify vulnerabilities and risks for IT and OT assets
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.
