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

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; that is what it is used for and then data from different sources can be fed into it, and they have good dashboards, risk meters, and virtualization."
"The risk context of any vulnerability is a valuable feature."
"The interface is fine."
"It is quite straightforward to set up."
"It is a stable solution. Stability-wise, I rate the solution a ten out of ten."
"The vulnerability scanning is the most important aspect of the solution for us."
"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, so you get complete visibility of your entire environment and tech operation, and the ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has."
"It is a very, very user-friendly tool...The setup is easy"
"The vulnerability management itself is the most valuable feature as well as references to the mitigation techniques."
"The solution is quite friendly."
 

Cons

"An improvement would be some sort of an integration with any GRC suite."
"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."
"The price could be lower, and the grouping of platforms on the dashboard can be included in the next release of the product."
"It would be helpful if Tenable could be more clear with regard to everything the solution can and cannot do with the particular license that you have."
"t needs additional reporting and intelligence features, as well as enhancements in AI-driven detection, which is still in its early stages."
"The solution’s pricing could be improved."
"I'd like to see them improve their support."
"The biggest problem with the solution is that if you're a small company, you're not going to be able to afford it, nor are you going to be able to manage it."
"My rating for customer service is three."
 

Pricing and Cost Advice

"I think the pricing is based on the number of endpoints, so it's more subscription-based."
"I would rate the pricing a five out of ten. It is in the middle."
"The cost is determined by the number of endpoints, which is approximately one dollar per endpoint."
"The solution is not too expensive."
"Tenable.io is not known for being a cheap product."
"Compared to other VM solutions, Tenable.io Vulnerability Management is expensive."
"The total cost we pay for this solution is over 45K. This is for a large education organization."
