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 initial setup is mostly straightforward."
"There is no burden of updating or upgrading this solution."
"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."
"It is pretty stable. I would rate it nine or maybe ten."
"The dashboard is pretty intuitive, and it lets you do a drill-down analysis of each vulnerability. That is something that brings a lot of value to the organization."
"It is a very, very user-friendly tool...The setup is easy"
"The solution's most valuable feature is providing a single pane of visibility on all the infrastructure and its status."
"It helps us create remediation projects and assign the console’s responsibility to specific engineers."
 

Cons

"An improvement would be some sort of an integration with any GRC suite."
"An improvement would be some sort of an integration with any GRC suite."
"It's not a user-friendly tool since it has a complicated interface."
"The solution must provide penetration testing."
"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."
"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."
"One area that they could improve is technical support. Oftentimes, it's not as good as it should be."
"I don't recommend Tenable.io Vulnerability Management for web scanning"
"The only drawback of the solution is that it is expensive."
"The pricing of the solution could be more reasonable."
 

Pricing and Cost Advice

"I think the pricing is based on the number of endpoints, so it's more subscription-based."
"The total cost we pay for this solution is over 45K. This is for a large education organization."
"Tenable.io is not known for being a cheap product."
"A yearly payment has to be made toward the solution's licensing costs."
"Tenable charges around $40 per device."
"The product costs us around $137,000 annually for 4000 to 5000 assets."
"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."
