Pros and Cons
- "The initial setup is mostly straightforward."
- "The product has many features and continues to develop its capabilities at a rapid pace."
- "I'd like to see them improve their support."
- "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."
What is our primary use case?
What is most valuable?
The product has many features and continues to develop its capabilities at a rapid pace.
It's done a lot of acquisitions and has really built out its cloud functionality. They're doing a good job of building out their cloud security.
The initial setup is mostly straightforward.
The solution is stable.
It can scale as necessary.
What needs improvement?
I'd like to see them improve their support.
It would be great if there was more integration with other third-party products. They have a robust API, so it's possible to write a script in Python and extend or integrate with another solution, however, will be great if they had this integration automatically.
For how long have I used the solution?
I've been dealing with the solution for three or four years.

Tenable Vulnerability Management
May 2026
Learn what your peers think about Tenable Vulnerability Management. Get advice and tips from experienced pros sharing their opinions. Updated: May 2026.
900,747 professionals have used our research since 2012.
What do I think about the stability of the solution?
The solution is stable. I haven't had any issues. There are no bugs or glitches. It doesn't crash or freeze. We use AWS infrastructure and find it to be very reliable.
What do I think about the scalability of the solution?
The general scalability is pretty good. It's easy to add on. We haven't had an issue with expansion.
At this point in time, I'm not sure if our clients intend to increase usage.
How are customer service and support?
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. It's not solving my problems fast enough.
Which solution did I use previously and why did I switch?
I've deployed Tenable.sc and other Tenable products. I've also dealt with FireEye.
How was the initial setup?
I've been implementing the solution for four years. Therefore, I do not find it to be a difficult process. In general, it is easy to deploy, however, it depends on the client. If they are cooperative, it is easier.
We need at least one person for deployment and maintenance.
What's my experience with pricing, setup cost, and licensing?
I can't speak to the exact cost of the solution.
There may be some features that we have to pay for that are extra. However, when someone wants to use Tenable.io only for vulnerability scanning and vulnerability management, there is no hidden cost.
Which other solutions did I evaluate?
We are partners with Tenable and therefore tend to lean towards their products more than others.
What other advice do I have?
We're partners. I mainly implement the solution.
I work with a variety of different versions. I use the whole Tenable portfolio.
I'd rate the solution eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

An easy-to-use solution with smooth configuration and broad scalability
Pros and Cons
- "The solution is easy to use and configuration is smooth with no complexities."
- "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."
- "Technical support requires constant follow up and that is an issue. I rate support a two out of ten."
What is our primary use case?
Our company has 25 technicians who use the solution to scan firewalls and produce scheduled compliance reports for various environments.
What is most valuable?
The solution is easy to use and configuration is smooth with no complexities.
The solution is one of the best tools in the market for vulnerability management and remediation. It functions exactly as we desire.
What needs improvement?
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.
Qualys is a competitor product and handles vulnerability tickets in this comprehensive manner.
For how long have I used the solution?
I have been using the solution for two years.
What do I think about the stability of the solution?
The solution is stable and I have only experienced hangs a few times.
What do I think about the scalability of the solution?
The solution is accessible from the private cloud so it is scalable to any needs.
How are customer service and support?
Technical support requires constant follow up and that is an issue. Once they are made aware of an issue, it takes time for them to find a resolution. I currently have three cases and have been waiting so long for updates that I have asked for escalation.
Support provided by Qualys is better because they work with you right away to resolve issues.
I rate support a two out of ten.
How would you rate customer service and support?
Negative
How was the initial setup?
The initial setup is straightforward and not hard to understand if you have worked with other solutions.
We experienced an authentication issue when the NetApp scanner was trying to log in to the system and firewall, but we modified the setting and the issue was resolved.
What about the implementation team?
We deployed the solution ourselves and the complexity depends on each environment.
For example, our company has AWS, Azure, and on-premise data center environments. Our infrastructure team builds a list of assets and then our technicians deploy the solution to conduct scans.
What's my experience with pricing, setup cost, and licensing?
The annual license is a bit costly but the solution is worth it.
Which other solutions did I evaluate?
We also use Qualys and like how it handles vulnerability tickets.
We moved to the solution because Qualys does not support Cisco Secure Firewalls and that is a requirement in our environment.
What other advice do I have?
While Qualys offers dual locations for vulnerability tickets, it is not difficult to use API calls to integrate the solution with ServiceNow for assigning mitigation.
Many companies use third-party tools like Jira to integrate things so it is not unusual. I do believe Tenable is working on an internal solution that will be available in the future.
I rate the solution an eight out of ten.
Which deployment model are you using for this solution?
Private Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Other

Intake Specialist at Maxtec
A powerful product that provides visibility across the entire tech surface and helps you to focus on the vulnerabilities that pose immediate risks
Pros and Cons
- "Tenable.io, in particular, is quite a powerful product; it looks at your traditional environment, which is pretty much anything that is on-premises, and it also goes a step ahead and covers your modern assets, which is anything that is currently sitting in the cloud, so you get complete visibility of your entire environment and tech operation, and the ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has."
- "They've been able to think about everything in terms of where the world is going and the type of assets that you've got. They've everything sorted out in that aspect, but you have to pay for most of the other components that they've got to give you complete visibility across your tech surface. If it already had those capabilities in-built, without having to add them on to take advantage of them, it would be a very compelling value proposition."
- "One area that they could improve is technical support. Oftentimes, it's not as good as it should be."
What is our primary use case?
I work for a company called Maxtec, and we are a distributor. One of the solutions that we used to distribute, not anymore, is Tenable. I've worked as the product manager for Tenable, and it is one of the products on which I've worked quite extensively. We stopped its distribution last year, and I stopped working with it at the beginning of 2022. We were using its latest version.
How has it helped my organization?
One of the biggest cutting-edge technologies that they were able to introduce is predictive prioritization. It has helped a lot of IT teams enormously that were heavily under the weight of vulnerabilities that they needed to remediate. Just in 2019, over 19,000 vulnerabilities were discovered, and about 10,000 of those vulnerabilities were rated between high and critical. The way predictive prioritization works is that it adds a lot of context and granularity, and it helps you understand which vulnerabilities actually pose an immediate risk to your environment. It eliminates the pressure that the IT teams were under in terms of remediation because now, they don't have to focus on 10,000 vulnerabilities. They can only focus on 3% of vulnerabilities that pose an immediate risk to their environment. That, for me, has been a cutting-edge technology and a game-changer in helping a lot of IT teams in focusing more on the risk that they need to address, at least within the next 30 days.
What is most valuable?
Tenable.io, in particular, is quite a powerful product. It looks at your traditional environment, which is pretty much anything that is on-premises, and it also goes a step ahead and covers your modern assets, which is anything that is currently sitting in the cloud. You get complete visibility of your entire environment and tech operation. The ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has.
The use of agents comes in very handy when a lot of the workforce is working from home, such as during COVID-19. Some of the traditional tools would not be able to monitor any of those devices that people would be working with, such as laptops, because they are remote. You can only audit their machines if they are on the business premises, but with Tenable.io agents, you can maintain that level of continuous monitoring, even if they are not on-premises at the time of the scan. The agents run the scans locally on the machine.
Tenable.io is a cloud-managed solution, but the scanners are sitting on-premises. They've also got some public cloud scanners that are sitting all over the world. They've got something called frictionless assessments, which is quite an interesting approach for vulnerability scanning of anything that is sitting in your AWS. You don't have to deploy the scanners. They've got sensors in there that are able to give you continuous monitoring without deploying scanners, doing any configurations, or inputting any credentials.
What needs improvement?
They've been able to think about everything in terms of where the world is going and the type of assets that you've got. They've everything sorted out in that aspect, but you have to pay for most of the other components that they've got to give you complete visibility across your tech surface. If it already had those capabilities in-built, without having to add them on to take advantage of them, it would be a very compelling value proposition.
Their support needs to be improved in terms of turnaround time.
What do I think about the stability of the solution?
It is stable.
What do I think about the scalability of the solution?
It is a cloud solution. Therefore, it is highly scalable. There is no limit to how many assets and devices you can handle.
In terms of verticals, in the public sector, we've seen a huge uptake. That could be because of compliance reasons. We've also seen it being used quite extensively within the banking and financial verticals. Those are the biggest users of the product. There has also been an uptake in other verticals but just not as big or as vast as the public sector and the finance and banking sector.
How are customer service and support?
One area that they could improve is technical support. Oftentimes, it's not as good as it should be. The turnaround time could be improved quite significantly.
How was the initial setup?
It is pretty easy and straightforward. For the cloud, you don't have to do anything on the management console. That is already set up for you. The only thing that you need to configure is your scanners that are sitting on-premise. For that, you just need a linking key that you obtain from Tenable.io so that there is directional communication between the cloud, your cloud instance, and various scanners that are sitting on-premises. It would be the same process if you want to install an agent, for example, on a machine. It would apply the same way. The only difference is that instead of choosing a scanner, you'd choose an agent.
What other advice do I have?
For future users of Tenable.io, I would recommend using a layered approach. Tenable.io has an open API. So, it can be integrated with SIEM solutions. You can look at integrating it with privileged access management or any SIEM solution so that you've got all the data being pumped into a centralized location, and you are able to read the data alongside other security events coming from the SIEM and privileged access management solutions.
Companies that are currently using Tenable.io can definitely start looking at integrating some of their security solutions for a much more robust security approach.
I would rate it a solid eight out of ten.
Which deployment model are you using for this solution?

Supports container scanning, and the technical support is good
Pros and Cons
- "The most valuable feature for me is container scanning because I am interested in CICD security."
- "Overall, I am quite happy with Tenable.io."
- "It would be helpful if Tenable could be more clear with regard to everything the solution can and cannot do with the particular license that you have."
What is our primary use case?
I am a consultant and I advise my clients from a security standpoint. My goal is to get them to maximize value from Tenable.io. I am also a user of it.
What is most valuable?
The most valuable feature for me is container scanning because I am interested in CICD security. The standard infrastructure scanning is pretty robust, which is why I was focusing on containers.
What needs improvement?
We had some challenges with the implementation because of Docker Version 2, although with help from the support team, we were able to proceed.
It would be helpful if Tenable could be more clear with regard to everything the solution can and cannot do with the particular license that you have. The information is not available on the web site and they should be more upfront about it.
For how long have I used the solution?
I have been using Tenable.io for between six and eight months. My company had acquired it before I joined, although it was not being utilized properly.
What do I think about the stability of the solution?
I have never encountered any issues relating to stability. I have never seen a scan crash, and we've been able to configure multiple scans to run concurrently. Everything appears to run smoothly.
What do I think about the scalability of the solution?
Other than running multiple scans concurrently, we have not looked at scalability. However, I have no doubt that we will be able to get support in order to meet our expectations.
How are customer service and technical support?
The support team is very good and we are quite happy with them. When we had the trouble with Docker Version 2, they responded and were able to help us troubleshoot, and then guide us to the resolution. It now works the way we wanted it to.
Which solution did I use previously and why did I switch?
I have worked with the open-source solution OpenVAS, as well as with Rapid7 and Qualys. I can see that Tenable.io is going to be one of the big players because they are doing very well in this space.
What's my experience with pricing, setup cost, and licensing?
I think that the price is reasonable for now, although given that everybody is looking to cut costs, I think that they should take measures to lower it. There are additional features that can be licensed for an additional cost.
What other advice do I have?
My advice for anybody who is implementing this product is to have all of the requirements documented and ready in advance. You match the solution to your requirements. Out of the box, we found that Tenable.io matched almost all of our requirements. The only clarification that we needed had to do with the Tenable.io Web App license.
We have a good understanding of how Tenable.io works with containers and infrastructure, but when it comes to deep driving into applications, databases, APIs, and toolkits that you have in your environment, you need a separate license for that. This is what the Web Application license is.
In order to enjoy the maximum value, you need to have the appropriate licensing.
Overall, I am quite happy with Tenable.io.
I would rate this solution a nine out of ten.
Which deployment model are you using for this solution?

A tool that provides great visibility of the vulnerabilities that need to consider in improving its interface
Pros and Cons
- "The best feature of the solution is the amount of visibility it provides of the vulnerabilities."
- "It's not a user-friendly tool since it has a complicated interface."
What is our primary use case?
We use Tenable.io Vulnerability Management for our organization's endpoint and server vulnerability management.
What is most valuable?
The best feature of the solution is the amount of visibility it provides of the vulnerabilities.
What needs improvement?
Improvements should be made to the solution to make it easy to use. It's not a user-friendly tool since it has a complicated interface. The solution needs to have a more user-friendly interface.
For how long have I used the solution?
I have been using Tenable.io Vulnerability Management for three years. I am using the solution's latest version.
What do I think about the stability of the solution?
It is a stable solution. Tenable.io is the leader in the market, having a very good database of vulnerabilities.

How was the initial setup?
The setup phase was good.
The setup phase could be completed in less than five minutes.
The deployment process was carried out through an automated process and wasn't done manually. It was done with the help of Intune.
Based on our requirements and business, we need around three to five people to deploy and maintain the solution.
What about the implementation team?
No consultants were involved in the setup phase since we chose to manage the installation part directly.
What was our ROI?
Considering our scenario, the solution is worth it.
What's my experience with pricing, setup cost, and licensing?
A yearly payment has to be made toward the solution's licensing costs.
Compared to other solutions, Tenable.io is expensive.

I like the Cloud Scanning feature the most, but they can improve in the area of role management and compliance reporting
Pros and Cons
- "It is pretty stable. I would rate it nine or maybe ten."
- "They should include better customization of the dashboard, and integration tools."
What is our primary use case?
We use Tenable.io for vulnerability scanning.
What is most valuable?
I like the Cloud Scanning feature the most.
What needs improvement?
They can improve in the area of role management and compliance reporting.
They should include better customization of the dashboard and integration tools.
For how long have I used the solution?
We have been partners with Tenable.io for four years.
What do I think about the stability of the solution?
It is pretty stable. I would rate it nine or maybe ten out of ten. I didn't realize that the solution will be dropped in availability.
What do I think about the scalability of the solution?
It is a scalable solution. I would like to rate it a six out of ten.
How are customer service and support?
Many times, I get some answers that are not suitable information for my query. Thus, I need to escalate our vendors and our contacts internally. When some task is escalated and some security engineer supports them, it becomes quite helpful. After all, we are a part of it. I am working with Tenable.io. So in general when I have some problems, it is a pretty big problem for me. And I need someone else for support. It is not a general problem that some customers can figure out.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
Two years ago, I was training for Rapid7. Since then, I have had no time to implement another solution. So we are just implementing Tenable.io right now. Also, we have some big Tenable.io projects. So, we are just working around Tenable.io. But I have some expectations to work in the future with another vendor for vulnerability management.
What's my experience with pricing, setup cost, and licensing?
I don't have any comparative options from another vendor. I just work at the retail level. I know it has a pretty high cost for some features. It's a security vendor, and the security solutions are pretty high-priced. I think Tenable.io is available at the mid-range of prices, maybe the mid-high range.
What other advice do I have?
I work with Tenable.io and implement this solution for many customers. I would rate it eight out of ten.
The solution needs either two engineers or one security specialist to maintain it.
Which deployment model are you using for this solution?

Helps us manage organizations with assets with no burden to update the solution
Pros and Cons
- "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."
- "The price could be lower."
- "The price could be lower, and the grouping of platforms on the dashboard can be included in the next release of the product."
What is our primary use case?
Our primary use case for the solution is managing organizations with assets. Our on-premises assets are in the private or public cloud so the customer doesn't need to have the server installed and deployed but can touch and go once the license has a provision. The user can use it right away.
How has it helped my organization?
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.
With Tenable.io, we can schedule scans, push policies, view scan findings, and control multiple Nessus scanners from the cloud. This enables the deployment of Nessus scanners throughout networks to both public and private clouds as well as multiple physical locations
What is most valuable?
There is no burden to update or upgrade the solution manually, so it's always up to date.
What needs improvement?
The price could be lower, and the grouping of platforms on the dashboard can be included in the next release of the product.
For how long have I used the solution?
We have been using the solution for approximately four years.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
The solution is scalable because if you want to extend the license, you can do it over a call every quarter. Additionally, the scaling does not require infrastructure requirements or additional infrastructure because all are hosted in the Tenable.io Vulnerability Management cloud.
How was the initial setup?
The initial setup is straightforward. However, once the account is provisioned for a user, Its just the data collector to set up Scanner/Agents, and it takes approximately two hours to set everything up.
What's my experience with pricing, setup cost, and licensing?
It costs approximately $2,300 yearly.
Which other solutions did I evaluate?
We chose this solution because it has a great reporting feature and provides the most CVE coverage and VPR. Additionally, the solution has been in the industry for a long time and performs well.
What other advice do I have?
I rate the solution an eight out of ten. The solution is good, but the price could be lower, and the grouping of platforms on the dashboard can be included in the product's next release. I advise new users to know the infrastructure system and networking. Additionally, there are videos and documentation that will assist them in getting set up to use the product right away.

Discovers quickly, very stable, and periodically updated, and but needs more integration
Pros and Cons
- "It is very stable, and it is updated periodically by adding new vulnerabilities."
- "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 can have more integration."
What is our primary use case?
It is useful for scanning the whole environment to check for any vulnerabilities. We can then start deploying or closing these vulnerabilities by applying the Windows or other product patches. In the end, we have an environment with no vulnerabilities, and we increase our security posture and security levels.
What is most valuable?
It is very stable, and it is updated periodically by adding new vulnerabilities. It can discover much quickly as compared to other vendors.
Its management console and portal make it easy to use and effective.
What needs improvement?
It can have more integration.
For how long have I used the solution?
I have been using this solution for three months.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
It is scalable.
How was the initial setup?
I haven't installed it on a customer's site. I just installed it in my lab in order to get familiar with the product, and that's it. It was just for testing.
It was a straightforward installation. Because it was done in my lab environment, it didn't take that much time. It took around three to four hours.
What about the implementation team?
I did it myself.
What other advice do I have?
I would recommend this solution at this time, but after installing it for more customers, my answer might change in the future.
I would rate this solution a seven out of 10.

Very mature and quite stable but could use a better user interface
Pros and Cons
- "They are on a good trajectory as a company and investing in R&D in the right ways."
- "The stability is excellent."
- "The solution seems to focus too much on enterprises, and they really need a product that works for SMBs."
- "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."
What is our primary use case?
Primarily we're a partner of Tenable and what we've done is we've essentially created a middleware. We created a middleware on top of Tenable.io engine, the API, and the middleware was developed back in 2003. It has gone through about three different iterations since then.
Essentially, we simplify their user interface. It's been designed so that the managed service providers, the MSPs, are able to use the Tenable system with our interface on top. In a sense, what we've done is dramatically dummied down the Tenable interface through the use of our own GUI. We connect to the Tenable API in the backend, however, they're doing the heavy lifting, so to speak, and we're just presenting the information in a much more logical, easily understood manner.
What is most valuable?
The API is pretty good.
The solution works well for enterprise-level organizations.
They're a standup product. They really are. They're one of the first in the industry which means they're a quite well-established site. It's pretty hard to improve upon.
The initial setup is pretty straightforward.
They are on a good trajectory as a company and investing in R&D in the right ways.
The stability is excellent.
The scalability is pretty good.
What needs improvement?
The solution seems to focus too much on enterprises, and they really need a product that works for SMBs. The enterprise product is too expensive for smaller companies, however, they really are looking for a product like this in the market.
It's too technologically advanced for SMBs - Tenable is kind of a little bit like flying a 747. There's a lot of bells and whistles and switches and things like that, that quite frankly are not used or not understood largely by the average user. If they don't begin to cater to smaller organizations, they'll likely lose market share.
They could use a better user interface that could be developed a lot better than it is. It really could be more intuitive.
For how long have I used the solution?
I've used Tenable for 20 years or so. 18 to be exact. It's been a good amount of time. I have a lot of experience with the company.
What do I think about the stability of the solution?
The stability is excellent. There are no bugs or glitches. It doesn't crash or freeze. It's one of the reasons we chose it. It's reliable and the performance is excellent.
What do I think about the scalability of the solution?
Aside from their licensing, which needs some serious reworking, when you get the licensing in order the scaling is not that bad. It's pretty much on-par in terms of what others are doing. However, getting the provisioning of the licensing and all of that stuff through their partners, namely Ingram Micro, is nothing short of pulling teeth really.
How are customer service and technical support?
I've never used technical support in the past. I've never had a need to. Therefore, I wouldn't be able to assess them. I can't say how knowledgeable or responsive they are.
Which solution did I use previously and why did I switch?
We've only been with Nessus. Nessus Professional came out way back in the day, in 2002, 2003, there was WebInspect which was then, bought by IBM. We used WebInspect which was another iteration of vulnerability scanning. It's kind of like Burp Suite, which is commonly used now. That was our only other experience. That was very far back, it's almost another lifetime.
How was the initial setup?
The initial setup is pretty straightforward. We've got staff members that are certified for decades, two decades or more, and they know their way around quite easily. It's quite easy in that regard to set up.
What's my experience with pricing, setup cost, and licensing?
In terms of the pricing side, I would say that they've lost a little touch on the pricing. It seems that the enterprise companies are the ones that primarily use Tenable for DIY security. However, the needs are much greater adoption in terms of the SMB space. These companies are screaming for attention. They've gotten interest from the hackers as hackers seem to be quite focused on the SMB space - which means they need protection. Most of the VA companies that are out there are servicing the enterprise and they all need the help. They've got the budget, they've got the resources, they have the CISSP certified guys on the bench taking care of their needs.
In terms of the volume of users interacting with the solution, you're looking at tens of thousands. As a service provider, we use the solution for companies of all sizes.
What other advice do I have?
We're a partner for Tenable Nessus.
The Tenable.io is what we're using currently. It suits our needs best due to the fact that it's in the cloud. The API is okay. It's not wonderful. Seems to serve a purpose.
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.
I would recommend other organizations use the product. People probably don't consider the amount of, let's say, understanding or comprehension that they need of their own network to truly be able to deploy and manage and get the results they're looking for, however. Many often underestimate all their skillsets. Tenable has a number of features and functionalities and it can be a little confusing for, let's say, a non-security savvy person. It could be a little bit of a challenge, to be honest. I'd suggest any company that considers it also does their homework first.
I'd rate the solution at a seven out of ten. It gets the job done. It really is smooth to operate once it's set up. It is for the most part pretty easy to set and forget.
