Nessus vs Orca Security: 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)

Initially, as we started using Orca Security, it was just a backup and disaster recovery solution but in recent months, it has introduced real security and patch management features.

Because of the way Orca's side-scanning technology works using snapshots, the downside is that the scanning is not performed in real-time so cannot provide true xDR capabilities.
