- "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."

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?
