Offers contextual prioritization and risk-based remediation of vulnerability
An improvement would be some sort of an integration with any GRC suite. There are a lot of GRC suites available, like Archer, MetricStream, Rsam, Protiviti, for example. So how would a solution like this work if my company has already invested thousands or maybe millions in a GRC solution? Do I still need it and how does it fit into an existing SAP environment? There could be interoperability, having more data sources, integrating Splunk, Qualys, FireEye, Rapid7, Carbon Black. I'm sure all that can be done to an extent, with a little more insight and a little more accuracy on the industry numbers and trends. I'd like the solution to offer any sort of assistance in any way with the remediation part, not just identification of vulnerability risk, and that is second.

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.

Quotes from Members
