Comprehensive asset visibility and OT operations support enhance risk mitigation
I use Armis for asset discovery and vulnerability assessments of the OT network Armis is easy to use. Very few software solutions have OT capabilities that do not impact OT operations. Its asset visibility is good as well. This comprehensive feature set is crucial for our operations.…
Chethan Gowda - PeerSpot reviewer
Windows Security Patching Operation III (Cyber Operations) at CBTS
Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers
Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.
