## Our take

What our shortlists say about the one we picked.

### [Qualys TotalAppSec](https://cybersectools.com/tools/qualys-totalappsec)

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.
