What our shortlists say about each one.
Best for: Enterprises consolidating DAST with Qualys VM and cloud asset inventory
The limitation is that TotalAppSec delivers the most value when you are already in the Qualys ecosystem, specifically running Qualys CSAM or VMDR. The integrations with those products are native and tight. As a standalone DAST solution evaluated in isolation, the complexity of the platform may outweigh the benefits for teams without existing Qualys investment. This is an enterprise play, and it is priced and scoped accordingly.

Best for: Teams already using Tenable for vulnerability scanning
It belongs here because it adds web app testing to the Tenable products many teams already use for vulnerability scanning, so web findings sit next to the rest. It fits teams of any size already on Tenable One or Security Center. Its listed integrations are all Tenable products, so if you want a scan on every release, ask how it connects to your CI/CD pipeline and ticketing.
