Likelihood to Recommend

Nessus

Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.

Qualys WAS

It does have its pros but they are outweighed by the cons. There are better scanners out there. WAS gets stuck at scanning a single page for such a long time that it barely covers any part of the application before reaching the 24-hour limit and concluding testing. It could be also because of the nature of our application, but I would expect dynamic scanners to be a bit smarter than this.

It's very much a plug and play application that the user can go into with limited knowledge and set-up scans in minutes.

They had a support page within the WAS to report any concerns or seek help. But the UI of that is not smooth. Regardless support staff were pretty responsive and helpful. They scheduled calls to understand and address our problems. Email support is good as well.

Alternatives Considered

Nessus

Tools like Qualys, Rapid7 stack up well against Nessus, but I think Nessus is superior overall when compared to them, given the features it has.
Tejas Gandhi | TrustRadius Reviewer

Qualys WAS

The Qualys Web Application Scanning (WAS) is integrated with our Qualys Cloud Platform so that we can have all the vulnerabilities in one single place. Also, the reporting capabilities of the Qualys Web Application Scanning (WAS) is way higher than any other vulnerability management tool in the market (especially in terms of compliance reports, such as PCI and SOX).
