A cost-effective and user-friendly vulnerability scanning solution, but it lacks application-level support for mobile devices
Pros and Cons
  • "I like the fact that it was not expensive. I like that it's user-friendly."
  • "It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."

What is our primary use case?

I evaluated, set up, and implemented Tenable Nessus for a client. They had four firewalls, about 500 endpoints, two servers, and one database server.

What is most valuable?

I like the fact that it was not expensive. I like that it's user-friendly.

What needs improvement?

It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features.

For how long have I used the solution?

I have been using Tenable Nessus for about six months.

The most dynamic solution on the market
Pros and Cons
  • "The solution is the most dynamic one I have seen thus far."
  • "EQA's and dashboards should be addressed in the next release."
  • "While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."

What is our primary use case?

We primarily use the solution for our customer vApp, the dynamic application testing using NetWeb application and security and the infra scanning. It allows us to do a weekly scan for our customers. 

How has it helped my organization?

The solution was a great help during the pandemic for closing down all those open vulnerabilities. Continuous scanning of the infra was helpful for identification on the web applications level.

What is most valuable?

The solution is the most dynamic one I have seen thus far. It is one of the best available solutions. It is the best vulnerability tool that is available at present. 

What needs improvement?

While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations. 

We feel the licensing cost to be too high for our customers and us. 

EQA's and dashboards should be addressed in the next release. 

For how long have I used the solution?

We have been using Tenable Nessus for four or five years. I believe that our practice team is doing so. 

What do I think about the stability of the solution?

The solution is highly reliable. 

What do I think about the scalability of the solution?

Scalability is not an issue. 

How are customer service and support?

Tech support is good. I think we are now partnered with Tenable.

How was the initial setup?

The initial setup was straightforward. The solution was very easy to set up and configure.

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

We have a yearly subscription license. 

We have a partnership for filling Tenable Nessus as a manager product for our customers. 

Though it is a good enterprise solution, it is likely too highly priced for smaller organizations. 

We feel the licensing cost to be too high for our customers and us.

What other advice do I have?

We have both on-premises and cloud-based deployment in our organization. 

The solution is good. 

I rate Tenable Nessus as a nine out of ten.

Very user friendly and affordable
Pros and Cons
  • "The trial version is very good for testing whether it will suit your needs."
  • "I have chosen Nessus because it's very simple to use and install."
  • "The report for counters is too simple and would be improved by a dashboard."

What is our primary use case?

I'm currently using the Nessus essentials for testing, it's installed on my Notebook. My company has only been in operation for one month so as soon as I close with my first client, I will buy the professional version. I used the solution in my previous job. 

What is most valuable?

I have chosen Nessus because it's very simple to use and install. Depending on the number of assets you scan, Nessus is also an affordable solution. Products such as Tenable IO and RapidLab, can become expensive depending on the number of IPs. So Nessus Pro is perfect for my needs right now.

What needs improvement?

I'd like to see a dashboard for this product because the report for counters is too simple. There needs to be something better for the client.

For how long have I used the solution?

I've been using this solution for five years. 

What do I think about the stability of the solution?

This solution is stable. 

What do I think about the scalability of the solution?

The solution is definitely scalable. 

How are customer service and support?

I've never needed to contact Tenable support, I've been able to resolve any issues myself. 

How was the initial setup?

The initial setup is very easy. Deployment takes less than two hours, it's simple.

What other advice do I have?

It's important to test the solution so you know that it works for your situation. They have a trial version so it's easy to test before you purchase it. 

I rate this solution eight out of 10.

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."
  • "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."
  • "Technical support could be more knowledgeable. Their support right now goes from awkward to funny."

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.

Which deployment model are you using for this solution?
