## Our take

What our shortlists say about the one we picked.

### [Checkmarx One DAST](https://cybersectools.com/tools/checkmarx-one-dast)

Best for: AppSec teams already using Checkmarx One

It is on this list because it is built for hard logins, from two-factor to single sign-on, and because it joins what code scans and live scans find about your APIs. It fits mid-sized and large AppSec teams already on Checkmarx One. If you do not run other Checkmarx scanners, the shared inventory and scores matter less, so judge it on its scanning alone.
