Featured Reviews

Cyber Security Specialist at UBS Financial
Customized dashboards and quick deployment support comprehensive asset management
We use the True Risk Score for vulnerability prioritization, though we do not solely rely upon it since some assets may be decommissioned soon or not in use. From Qualys CyberSecurity Asset Management, we primarily focus on internet-facing assets. We have created separate tasks for internet-facing assets and track the True Risk dashboard specifically for these assets. If the True Risk Score is higher for any internet-facing assets, then we take action accordingly. The True Risk Score is very helpful for prioritization. The initial setup was straightforward and easy. We needed to create customized tags, group them twice, and validate whether the operating system detection was true positive or false positive. We encountered some false positives, which required coordination with the IT team for verification. In six months, we had approximately 20-25 machines that needed verification on a weekly basis. We coordinated with the IT team to identify the exact operating system specifications.
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.
