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. Developers and small security teams hunting XSS in web applications need XSSCon because it cuts through setup overhead; you run it, it finds reflected and stored XSS fast, no licensing friction. At 222 GitHub stars with consistent recent commits, the tool has proven reliable enough for teams that don't need fancy reporting or integration workflows. Skip this if your buyer is looking for a commercial vendor with SLA guarantees or needs DAST capabilities beyond XSS detection; XSSCon deliberately stays narrow.
