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 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."
"The solution's most valuable feature is providing a single pane of visibility on all the infrastructure and its status."
"The best feature of the solution is the amount of visibility it provides of the vulnerabilities."
"They are on a good trajectory as a company and investing in R&D in the right ways."
"The vulnerability scanning is the most important aspect of the solution for us."
"The ease of use, the automated scanning facility, and their good support mechanism are all valuable."
"Tenable.io Vulnerability Management is an easy-to-use product. I"
"A new user can easily understand the workflow, even if they are creating users for other divisions and the user is a beginner."
 

Cons

"An improvement would be some sort of an integration with any GRC suite."
"I would not say very expensive for Tenable Vulnerability Management; it is not prohibitive, but at the same time, there are some other tools in the marketplace which are offering the same kind of services that Tenable offers, the same kind of features that Tenable has offered at a lesser cost."
"Tenable could improve visibility into assets, including automated asset tagging. You should be able to automatically tag assets based on location, function, ownership, etc. That would help us because we spend a lot of time identifying and tagging assets by hand."
"The product is a bit expensive."
"I'd like to see them improve their support."
"They should include better customization of the dashboard, and integration tools."
"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 solution is a bit slow."
"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."
 

Pricing and Cost Advice

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