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. Security engineers validating CSPM tools or building internal cloud posture benchmarks should use TerraGoat to stress-test their scanning logic against real misconfigurations rather than vendor-curated demos. The repository contains over 50 intentional infrastructure-as-code flaws spanning AWS, Azure, and GCP, giving you actual Terraform to run detections against instead of abstract test cases. Skip this if you need a production-grade scanning tool; TerraGoat is a training ground, not a remediation platform.
