Very user friendly and affordable
Pros and Cons
  • "The trial version is very good for testing whether it will suit your needs."
  • "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.
