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."

"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 solution is very simple to use."

"The vulnerability scanning is the most important aspect of the solution for us."

"Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate."

"It's a great product, and it brings more value with every improvement in the quarter."

"I would rate Tenable's dashboards and reporting capabilities for illustrating security posture a nine out of ten, with ten being the best."

"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."

"They are on a good trajectory as a company and investing in R&D in the right ways."

"The best feature of the solution is the amount of visibility it provides of the vulnerabilities."

Cons

"An improvement would be some sort of an integration with any GRC suite."

"Technical support from Tenable is rated six out of ten. It needs improvement in response time and addressing feature requests promptly."

"t needs additional reporting and intelligence features, as well as enhancements in AI-driven detection, which is still in its early stages."

"It can have more 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."

"Technical support requires constant follow up and that is an issue. I rate support a two out of ten."

"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."

"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."

"We'd like to see a bit more user-friendliness."

More Tenable Vulnerability Management cons

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."

"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 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 solution is not too expensive."

"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."

"A yearly payment has to be made toward the solution's licensing costs."
