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 price of Tenable.io Vulnerability Management is reasonable as it is ten times cheaper than other options."
"They are on a good trajectory as a company and investing in R&D in the right ways."
"It's a recommended tool for penetration testers because it's effective for that purpose."
"You can customize each point in new scans."
"The initial setup is very straightforward."
"The product has many features and continues to develop its capabilities at a rapid pace."
"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."
"It is pretty stable. I would rate it nine or maybe ten."
 

Cons

"An improvement would be some sort of an integration with any GRC suite."
"The user interface could be improved by being able to change the user interface to fit your position or your job. The graphs are set in stone and you can only print reports."
"The one drawback that we have found is the reports. We are still getting reports from Tenable.sc since the maturity levels on the reports are lacking."
"Tenable is a full-service product, but it still has a lot of improvements to make, so I'd recommend exploring other products before implementing it."
"The product is a bit expensive."
"The tool's reports are bad. They're not very customizable or flexible. During audits, we often have to exclude things that aren't relevant to our organization, but we can't do that easily with the reports. They come in HTML or PDF format, and we can't compare current results with previous ones in Excel because we never receive reports in Excel."
"I would evaluate Tenable Vulnerability Management's customer service and technical support as average."
"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 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."
"The cost is determined by the number of endpoints, which is approximately one dollar per endpoint."
"Tenable.io is not known for being a cheap product."
"The tool is reasonably priced."
"Compared to other VM solutions, Tenable.io Vulnerability Management is expensive."
"Tenable charges around $40 per device."
"The product costs us around $137,000 annually for 4000 to 5000 assets."
"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."
"Yearly payments are to be made toward the licensing cost of the product. It is neither a cheap nor an expensive product."
