How are customer service and support?
Technical support could be more knowledgeable. Their support right now goes from awkward to funny. Sorry to say that, but Tenable Nessus support isn't working as it should. They act fast, but their solutions don't always work. I've been in several situations at work where I had to find my own solutions.
How was the initial setup?
The initial setup and installation are pretty straightforward. Let's say 15 minutes to compile the plugin. It would take about half an hour to an hour to set up and deploy.
What's my experience with pricing, setup cost, and licensing?
One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies.
What other advice do I have?
On a scale from one to ten, I would give Tenable Nessus an eight.
Which deployment model are you using for this solution?
On-premises

Easy to set up and use, reasonably-priced, and works well out of the box
Pros and Cons
- "Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
- "My advice for anybody who is considering Tenable Nessus is that it is easy to install, easy and straightforward to use, and not expensive."
- "The reports are okay, but the interface is a bit difficult to navigate in some cases."
- "Nessus is not very good at identifying web application vulnerabilities, which means that we need to buy another product like Acunetix or EMC Networker to handle that part."
What is our primary use case?
Our use cases are pretty straightforward. We primarily use it for conducting vulnerability scans.
What is most valuable?
Out of the box, the product works well for us, so it's not a tool that we need to customize very much.
What needs improvement?
The reporting interface is in need of improvement. The reports are okay, but the interface is a bit difficult to navigate in some cases.
Nessus is not very good at identifying web application vulnerabilities, which means that we need to buy another product like Acunetix or EMC Networker to handle that part. This is an area that could be enhanced because we would prefer to have these capabilities in one application.
For how long have I used the solution?
I have been using Tenable Nessus for more than 10 years.
What do I think about the stability of the solution?
Tenable is a reliable solution.
What do I think about the scalability of the solution?
We have not had any use cases that required scaling.
Our installation is a single tenant.
How are customer service and technical support?
We haven't had the need to contact technical support.
Which solution did I use previously and why did I switch?
Many years ago, we tried Nexpose by Rapid7.
How was the initial setup?
The initial setup was easy and very straightforward.
It took about half an hour to deploy, including all of the updates. It is the updates that take time to complete.
What's my experience with pricing, setup cost, and licensing?
We pay approximately $2,500 on a yearly basis. We do not pay any fees in addition to the standard licensing costs.
What other advice do I have?
Ultimately, we plan to use this product less because it is something that we advise our customers to buy for themselves. They should not be using our solution.
My advice for anybody who is considering Tenable Nessus is that it is easy to install, easy and straightforward to use, and not expensive. These are the reasons that we advice our customers to use it.
I would rate this solution an eight out of ten.

I like its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually
Pros and Cons
- "The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually. The output is quite reliable."
- "The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually."
- "In terms of what could be improved, I would say its reporting portion."
- "We operate in small and medium enterprises and for them, Nessus is becoming expensive."
What is most valuable?
The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually. The output is quite reliable.
What needs improvement?
In terms of what could be improved, I would say its reporting portion.
Additionally, we have the on-prem version, but sometimes we want to have an on-cloud deployment as well for certain projects, although not so many. The people who used it on cloud didn't find it as good as the version they were using on-prem. Overall, the cloud version could be improved.
For how long have I used the solution?
I have been using Tenable Nessus for about three years now. We are currently using the latest version.
What do I think about the stability of the solution?
In terms of stability, recently we are seeing many updates coming in and we are finding that the updating model with its latest releases may be a little buggy. So sometimes deployment may take a couple of times and Nessus takes its own time for updating, thereby delaying the deployment time. Of late is, we are seeing updates coming in very frequently. So when we deploy it, it just updates again and again and that almost doubles the time.
What do I think about the scalability of the solution?
Tenable Nessus is scalable. That's not an issue.
How are customer service and technical support?
We did reach out to technical support. I think it was just once, but it took them a long time to respond. Maybe it was case specific, but they took a few days to get back to us and we didn't expect that. Now they've completely changed the model to email support, so we send the email and we'll have to wait until the guys answer us back.
How was the initial setup?
The initial setup on-prem and on-cloud did not have any issues. It just took a couple of hours.
What other advice do I have?
On a scale of one to ten, I would give Tenable Nessus an eight.
What happens is Nessus keeps on updating and this becomes a showstopper. We are unable to proceed with the vulnerability scans or testing if we do not update to the latest available patch. We can understand the risk if it's maybe one version earlier, meaning, we understand something was updated with XYZ patch but there should be something which gives us an option so that not all of our deployments need to have the latest patch. This would save the deployment time because of frequent updates.
I would recommend Tenable Nessus. Especially the commercial model. We operate in small and medium enterprises and for them, Nessus is becoming expensive. Because of this I may not buy Nessus this year and I might switch to Qualys, for example. Overall, Tenable Nessus is not so price pocket friendly for small and medium users.

Largely problem-free with good scanning capabilities and a good interface
Pros and Cons
- "The automatic scanner and scheduler are pretty cool."
- "The interface is excellent; it makes it very user friendly and easy to navigate for the most part, and the product is pretty problem-free so we don't have any real issues with it."
- "The reporting is a bit cumbersome."
- "The reporting is a bit cumbersome."
What is our primary use case?
I primarily use the solution for vulnerability scanning within our organization.
What is most valuable?
The automatic scanner and scheduler are pretty cool.
The interface is excellent. It makes it very user friendly and easy to navigate for the most part.
It's a pretty solid product. I pretty much like almost all of it.
The product is pretty problem-free. We don't have any real issues with it.
What needs improvement?
The reporting is a bit cumbersome.
A lot of times you have got to, if you want to test things, go in and then back all the way out, and then try something else, and that just becomes cumbersome.
The testing functionality could be better.
The way they had set up the scan sometimes is difficult as well. It's partly due to how it's set up where I am. It's not necessarily a Tenable thing, however, the user, how they assign users and roles, is strange. Sometimes if a coworker sets up a scan, I can't start it or stop it. That's just something that may be an issue on our set-up and not a Tenable issue.
For how long have I used the solution?
I've been using the solution for a while. I've probably been using the solution since 2015. It's been over five years at this point.
What other advice do I have?
We're just customers. We're end-users. We don't have a business relationship with the company.
We're using the solution as what I would consider a hybrid, where the security center is managed by another group. However, we have a scanner in our network that connects back to the security center and the DOD of Azure.
We're largely happy with the product. Overall, I'd rate the solution eight out of ten. If it weren't for the reporting or the scanning difficulties, I would rate it higher.

Fast and easy to use, with good reporting and good support
Pros and Cons
- "The most valuable features are that it's fast, it's easy to use and it provides good reports."
- "The most valuable features are that it's fast, it's easy to use, and it provides good reports."
- "Remediation needs improvement."
- "Remediation needs improvement. They are providing a lot of superseded KBs as remediation."
What is our primary use case?
I have been using Tenable Nessus for my personal use. It works well.
I am using this solution for testing.
What is most valuable?
The most valuable features are that it's fast, it's easy to use, and it provides good reports.
What needs improvement?
The only thing that I don't like is KBs information. For example, if we scan our workstation and you go to the results report that Nessus provides, we are going to see a lot of KBs as remediation. But in most cases, the KBs are always superseded.
Also, we are not able to apply those because Microsoft has already released a new TB.
Nessus is not doing a good job in updating its remediation section of the reports.
Remediation needs improvement. They are providing a lot of superseded KBs as remediation.
For example, when you share that with several team members or with one individual, and you ask them to work on this, they reply with Microsoft already has something new.
For how long have I used the solution?
I have been using Tenable Nessus for approximately two years.
What do I think about the stability of the solution?
This solution is stable. I have not experienced any issues. It worked fine.
What do I think about the scalability of the solution?
It's a scalable solution. I have not had any problems.
I am the only person using this solution.
How are customer service and technical support?
Technical support is good. They provided information that is needed.
Which solution did I use previously and why did I switch?
Previously, I was not using another solution. I use Nessus through a course that I was taking in the security field.
How was the initial setup?
The initial setup was straightforward.
What about the implementation team?
We did not use a vendor or vendor team to implement this solution.
Which other solutions did I evaluate?
I have evaluated one other solution, but because of my company policies. I can't share that information.
Tenable has Tenable.io, and I believe that they have the remediation updated, but Tenable Nessus Professional does not. I don't think that they will continue to keep it available in the market. They should probably decommission it.
Remediation is better in other tools than with Nessus.
What other advice do I have?
For anyone who is interested in this solution, they should test the scan timing to see if it consumes a lot of time or not.
Research the remediation information to see if it is okay, or trust proof or not.
The reporting works well and it allows you to share. Also, support is important.
I would rate Tenable Nesuss an eight out of ten.

Quickly scans and detects new vulnerabilities
Pros and Cons
- "Tenable Nessus is cheap and flexible."
- "Using Nessus, we are able to scan and locate any potential vulnerabilities that our clients may have and point them out to them."
- "The professional version is not very scalable."
- "The professional version is not very scalable. It's not really scalable considering the number of assets and clients that I have."
What is our primary use case?
We use Tenable Nessus to provide service to our bank.
I use it to provide our main service related to our big management.
Other than providing information security to our clients, it is our information security provider, service provider — we manage it. Using Nessus, we are able to scan and locate any potential vulnerabilities that our clients may have and point them out to them.
I am not sure how many users we have using this solution, but we have more than 100,000 assets distributed between roughly 40 clients.
What is most valuable?
Tenable Nessus is cheap and flexible.
What needs improvement?
Currently, they don't have all of the features that I am looking for. I am looking for a technology that installs agents into the machines to perform complicated scanning. That's a good feature that I'm looking for.
Our issues are not all due to Tenable Nessus; we have more than one console that we administrate.
For how long have I used the solution?
I have been using this solution for 10 to 15 years.
I use this solution on a regular basis at my current company. I used it at my previous company as well.
What do I think about the stability of the solution?
This solution is quite stable.
What do I think about the scalability of the solution?
The professional version is not very scalable. It's not really scalable considering the number of assets and clients that I have.
Many of our clients would like to switch to a better solution.
How are customer service and technical support?
The technical support is great. We have called them a few times and they have always helped us.
How was the initial setup?
The initial setup was pretty straightforward. Within a week we had set up all of the infrastructure and were ready to deploy.
