### [Snyk API & Web](https://cybersectools.com/tools/snyk-api-and-web)

Best for: Developer teams adding DAST to a Snyk setup

It earns a place because it covers both APIs and JavaScript apps, can run behind the firewall, and gives developers fix steps with each finding. It fits teams from startups to large companies, and most naturally developer teams that already use Snyk. If that is you, ask how these findings sit next to your current Snyk results before you buy.
