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.

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

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

Pros

"The risk context of any vulnerability is a valuable feature."

"The solution's most valuable feature is providing a single pane of visibility on all the infrastructure and its status."

"The solution provides seamlessness, a perfect UI, and identity management for office operations. We are most vulnerable to users. Therefore, it is crucial to implement the right solution to ensure proper user access and resource management."

"Tenable.io, in particular, is quite a powerful product. It looks at your traditional environment, which is pretty much anything that is on-premises, and it also goes a step ahead and covers your modern assets, which is anything that is currently sitting in the cloud. You get complete visibility of your entire environment and tech operation. The ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has."

"Tenable is user-friendly and excels in reporting."

"It has greatly impacted us by providing asset visibility."

"The ease of use in terms of scanning assets is valuable."

"It is pretty stable. I would rate it nine or maybe ten."

"The vulnerability scanning is the most important aspect of the solution for us."

Cons

"An improvement would be some sort of an integration with any GRC suite."

"I would like the solution to cover the whole cycle of mitigation since it's an area where the solution currently lacks."

"The solution must provide penetration testing."

"An area of improvement for this solution is being able to customize the dashboard. For example, the dashboard does not allow us to view a previous months vulnerability results alongside current results to make comparisons."

"It's not a user-friendly tool since it has a complicated interface."

"The solution seems to focus too much on enterprises, and they really need a product that works for SMBs."

"The initial setup is complex and has room for improvement."

"Users get confused between VPR and CVSS ratings."

"The only drawback of the solution is that it is expensive."

More Tenable Vulnerability Management cons

Pricing and Cost Advice

"I think the pricing is based on the number of endpoints, so it's more subscription-based."

"The solution is not too expensive."

"Tenable.io Vulnerability Management's pricing solution model isn't great."

"A yearly payment has to be made toward the solution's licensing costs."

"Tenable charges around $40 per device."

"On a scale of one to ten, where one is low, and ten is high price, I rate the pricing an eight. So, it is a pretty expensive solution."

"The total cost we pay for this solution is over 45K. This is for a large education organization."

"The tool is reasonably priced."

"Tenable.io is not known for being a cheap product."
