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.

Continuous monitoring has improved OT threat detection and now provides faster, accurate alerts
The best features of Tenable Vulnerability Management include vulnerability scanning, asset discovery, continuous monitoring and alerting, and the ability to report through the dashboard. The dashboard is fully customized towards our environment, and we can use that for our advantage. Out of those features, I find myself relying on the vulnerability scanning the most because it identifies known vulnerabilities and gives us the ability to understand if there is any missing configuration or security configuration. It reduces the exposure to cyber attacks and gives us a detailed view of how the OT environment is functioning. Tenable Vulnerability Management features are great, and the reporting and dashboards are easy and customizable for our environment. The reporting tool gives us immediate information or alerts based on the set parameters that we have within the infrastructure. It gives us a threat level as high, medium, or low, and this can help us to identify or determine if there is any known threat within the environment. The governance and security of Tenable Vulnerability Management is within our control, meaning the user has the power or the authority to work with the AI and to allow the AI to work within your environment in terms of what you want. For instance, the OT environment is something that is very sensitive, and you will not want the AI management tool to take over or to do certain actions within the OT environment. Therefore, as a user, you have control over the AI. Tenable Vulnerability Management provides accuracy and reliable output because it is active, it is real, and it gives updated information. The threats are real based on the alerts that we get, and after reviewing, we are sure that what we see is within our environment and it is accurate.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

"The risk context of any vulnerability is a valuable feature."
"It is a very, very user-friendly tool...The setup is easy"
"It is useful for scanning the whole environment to check for any vulnerabilities, allowing us to deploy patches and close these vulnerabilities so we end up with an environment with no vulnerabilities and increased security posture and security levels."

"Technical support has been good. They respond quite quickly."

Cons

"An improvement would be some sort of an integration with any GRC suite."
"The product is a bit expensive."
"The solution seems to focus too much on enterprises, and they really need a product that works for SMBs."

"I'm not satisfied with the reporting structure."

"I would rate the pricing a five out of ten. It is in the middle."
