A remote security scanning tool that's pretty good to optimize
Pros and Cons
  • "I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."
  • "Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better."

What is our primary use case?

I'm using Tenable Nessus for my personal projects and vulnerability assessment, but I can't discuss what I do at work with you.

What is most valuable?

I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product.

What needs improvement?

Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better.

For how long have I used the solution?

I have been using Tenable Nessus as a worker in America for about 15 years now.

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.

Very user friendly with good dashboards
Pros and Cons
  • "User friendly and good dashboards."
  • "Consumes more system resources when it's running."

What is our primary use case?

I'm using Tenable for a project I'm working on. The primary use case is for web application scanning and we're also able to conduct infrastructure scanning and network scanning. I'm not using all the features. 

What is most valuable?

It's a user friendly solution and I like the dashboards. 

What needs improvement?

Unfortunately, the solution consumes more system resources when it's being run and I'd like that to be reduced. 

For how long have I used the solution?

I've been using this solution for three months. 

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.

How was the initial setup?

The initial setup was very easy, it didn't take more than 10 minutes. It does depend on internet speed so sometimes deployment might take longer. 

What other advice do I have?

I rate this solution an eight out of 10.

Great scanning capabilities for servers, but limited when it comes to networks
Pros and Cons
  • "The solution is great for scanning servers."
  • "The features are limited when it comes to scanning network devices for vulnerabilities."

What is our primary use case?

As new upgrades to the software come out periodically, I am currently using the latest version. 

What is most valuable?

I feel comfortable with the solution's vulnerability scanning capabilities.

What needs improvement?

While the solution is great for scanning servers, its features are limited when it comes to scanning network devices for vulnerabilities. 

For how long have I used the solution?

I have been using Tenable Nessus since 2015. 

How are customer service and technical support?

I can say that I am satisfied with Tenable Nessus' support and customer relations, which is why I'm still with the solution.

Technical support is very user-friendly. Upon entering their forum I can easily find the answers I seek, which I feel to be understandable and helpful. I have not any issues with the software that would have given me reason to engage technical support. 

Which solution did I use previously and why did I switch?

I did not use an alternate solution prior to Tenable Nessus and have been using it since the inception of my career in information security. 

How was the initial setup?

The installation of the solution was extremely easy. 

What about the implementation team?

There was no need for me to involve my system administrator in the installation process, as I was able to handle it on my own. It is easy to install the solution on any server. 

What's my experience with pricing, setup cost, and licensing?

The price is reasonable. 

What other advice do I have?

I am actually using the solution in three or four different organizations, including Engro and Martin Dow. 

There are two or three people using the solution in my organization on an ongoing basis in key dedicated positions. 

As Tenable Nessus lacks adequate network vulnerability scanning features, I rate it as a seven out of ten.

Good vulnerability management and easy to set up but needs more integration capabilities
Pros and Cons
  • "The initial setup is very straightforward."
  • "We'd like to see more integration potential within the solution."

What is our primary use case?

We primarily use the solution for vulnerability management.

When it comes to servers and scanners, or servers and endpoints, you can discover the vulnerabilities that might be on the other end. You can see, for example, if
you have a gap in vulnerabilities in specific servers or specific endpoints, and you if have to close the. You can really see the risks that might be encountered within your environment.

What is most valuable?

The solution is very good at vulnerability management. It gives you great visibility of visibilities.

The solution is stable. 

The initial setup is very straightforward.

What needs improvement?

We'd like to see more integration potential within the solution.

They tend to do a new release every quarter, and will ultimately continue to add more features.

For how long have I used the solution?

We've been using the solution for two months. We've been looking into it over that time.

What do I think about the stability of the solution?

The solution is pretty stable. There are no bugs or glitches. It doesn't crash or freeze. Its performance is very reliable. 

What do I think about the scalability of the solution?

I can't speak to the scalability. We have never tried to scale the solution.

I'm the only person in my organization that uses the solution. I don't have plans to increase usage at this time.

How are customer service and technical support?

I can't speak of technical support's knowledgeability or helpfulness. I haven't used them before and therefore couldn't really evaluate them very well.

How was the initial setup?

The solution is very straightforward and pretty simple. There isn't too much complexity or difficulty involved. A company shouldn't have any issues with the initial setup.

What about the implementation team?

I handled the installation myself. I didn't need the assistance of a consultant or integrator.

What's my experience with pricing, setup cost, and licensing?

We pay a yearly licensing fee.

I can't speak to the exact pricing. It's not an aspect of the solution I directly deal with.

What other advice do I have?

We're using the latest version of the solution. I can't speak to the exact version number.

I'd rate the solution at a seven out of ten. It's pretty great at vulnerability management, however, there are always ways to improve it.

I'd recommend the solution to other users.

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."
  • "The reports are okay, but the interface is a bit difficult to navigate in some cases."

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."
  • "In terms of what could be improved, I would say its reporting portion."

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 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.

Which deployment model are you using for this solution?

Hybrid Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
