What our shortlists say about each one.
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.

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.
