"IT Professional using Nessus"

What do you like best? Nessus is an easy to use tool that doesnt require years of expertise to be able to run and understand how to conduct vulnerability scans.

"We use it mainly for penetration testing purposes"

"We use it mainly for penetration testing purposes"

"Easy to use, reliable, and up to date."

What do you like best? It works, and it works well. I like that it's updated daily with new signature and vulnerabilities. It's incredibly easy to get a pre-configured scan started, and just as easy to automate it. I like the granularity that you can configure scans with. The reporting features are great, but we export the reports to a vuln manager. What do you dislike? It can be kind of confusing unless you can figure out their menus and terminology. It is also sometimes quite slow without ...

"Nessus scanning"

What do you like best? Nessus scanning in and of itself is rather simple. It is nice that debugging is built in to the gui and logs can be easily retrieved. Nessus is definitely best when deployed with Security Center. What do you dislike? Some of the logic built in to the Cisco handler didnt make sense. When the logic was presented with a #, it wouldn't issue the enable password required for escalation. Getting the logic fixed for this issue took over 9 months to resolve. What problems are ...

"Excellent software"

What do you like best? provides insight on your environment. Easy to install and to operate. Reporting add a lot of value for upper management. What do you dislike? Once the vulnerabilities are identified, we must fix and re-scan to validate they disappeared. Sometimes Nessus is still showing the vulnerability even if the fix is applied Recommendations to others considering the product: great product. What problems are you solving with the product? What benefits have you realized? Security ...
