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."
"It helps us create remediation projects and assign the console’s responsibility to specific engineers."
"The stability has been very good overall."
"The price of Tenable.io Vulnerability Management is reasonable as it is ten times cheaper than other options."
"The initial setup is not complex."
"It is easy to manage. Most of the information the tool provided helped to further investigate the vulnerability and its impact."
"The vulnerability scanning is the most important aspect of the solution for us."
"The vulnerability scanning has been great as it's helped us to define some issues around the updates of some things, and some items surrounding services we need to take care of."
"They are on a good trajectory as a company and investing in R&D in the right ways."
 

Cons

"An improvement would be some sort of an integration with any GRC suite."
"They need a better approach to support. When I have hard questions that need answers to, I prefer to jump to L3 support instead of getting pushed to L1."
"It can have more integration."
"One area that they could improve is technical support. Oftentimes, it's not as good as it should be."
"AI integration for reporting in Tenable would be beneficial."
"Tenable Vulnerability Management is not very effective for real-time risk prioritization for our organization's security strategy."
"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."
"They've been able to think about everything in terms of where the world is going and the type of assets that you've got. They've everything sorted out in that aspect, but you have to pay for most of the other components that they've got to give you complete visibility across your tech surface. If it already had those capabilities in-built, without having to add them on to take advantage of them, it would be a very compelling value proposition."
"The shortcoming of the solution that needs improvement is related to its capability to do vulnerability assessments on applications."
 

Pricing and Cost Advice

"I think the pricing is based on the number of endpoints, so it's more subscription-based."
"Tenable charges around $40 per device."
"The product costs us around $137,000 annually for 4000 to 5000 assets."
"The total cost we pay for this solution is over 45K. This is for a large education organization."
"Tenable.io Vulnerability Management's pricing solution model isn't great."
"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 tool is reasonably priced."
"Yearly payments are to be made toward the licensing cost of the product. It is neither a cheap nor an expensive product."
"A yearly payment has to be made toward the solution's licensing costs."
