Nessus vs Qualys Cloud Platform: Which is best for you?

good for discovery, fingerprinting, and finding CVEs for systems/software

The only flaw of Nessus is that if you don't purchase the "Tenable Web App Scanning" subscription, doing authenticated scans on web apps (especially if they implement authentication mechanisms such as SSO) presents problems, since even specifying credentials (or cookies)

Overall, the product is user-friendly with robust vulnerability scanning and has a large library of software updates.

It's interface is easy to use and has comprehensive product features for IT professionals and security.
