CST VerdictShort answer
Security teams managing REST, SOAP, and GraphQL APIs across multiple domains will get the most from AppCheck API Scanner because it actually discovers endpoints instead of relying on incomplete specs, then tests authorization flaws that static scanners consistently miss. The fixture data generation from Swagger and GraphQL schemas, combined with HMAC and AWS v4 signing support, means you're scanning real API behavior rather than guessing payloads. Skip this if your APIs are behind strict API gateways or if you need post-breach response capabilities; AppCheck is built for vulnerability identification, not incident recovery. Teams running distributed web applications and APIs who need to validate fixes without waiting for manual retesting will get the most from Cobalt DAST; its remediation validation workflow cuts the cycle between developer handoff and security sign-off. The platform integrates authenticated scanning across subdomains with false positive filtering via fingerprinting, reducing alert fatigue that kills DAST adoption. Skip this if your organization needs coverage beyond web applications or relies on a vendor pentest program as your primary validation layer; Cobalt DAST is automated scanning, not a replacement for human testers.
