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; 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 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."
"Tenable.io Vulnerability Management gives a good ROI in the long run, though it would be better with a pay-as-you-go model."
"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 product has many features and continues to develop its capabilities at a rapid pace."
"The solution creates vulnerability tickets within the VM profile but should also include them under the Remediation tab so the fixes can be viewed in the ticketing queue."
"The ease of use in terms of scanning assets is valuable, and it has a diverse checklist when it comes to vulnerability databases."
"It's a recommended tool for penetration testers because it's effective for that purpose."
"By making different resources available for sharing among users and groups, Tenable.io provides endless possibilities for creating customized workflows for vulnerability management programs, regardless of any of the numerous regulatory or compliance drivers that demand keeping your business secure."
 

Cons

"AI integration for reporting in Tenable would be beneficial."

"Tenable.io Vulnerability Management could be improved with an increased number of dashboards and MSSP integration."
"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."
 

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."
"There are additional features that can be licensed for an additional cost."
"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."
"Yearly payments are to be made toward the licensing cost of the product. It is neither a cheap nor an expensive product."
"The tool is reasonably priced."
"The solution is not too expensive."
"The cost is determined by the number of endpoints, which is approximately one dollar per endpoint."
