What our shortlists say about each one.
Best for: Teams scanning diverse app types including SPAs, APIs, and legacy HTML
Acunetix fits the widest range of organization sizes on this list, from SMB to enterprise. That breadth comes with a trade-off: the platform is not as deeply integrated into the broader Checkmarx or Qualys ecosystems as some competitors. If you want a standalone DAST scanner that covers a lot of ground without requiring a platform commitment, Acunetix is a strong choice.

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.
