AppCheck API Scanner vs AppCheck Infrastructure Scanner: Side-by-Side Comparison (2026)

Short 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. SMBs and mid-market teams without dedicated vulnerability management staff should pick AppCheck Infrastructure Scanner for its unlimited scanning and users, removing seat-based licensing friction that kills adoption. The proprietary VulnFeed database detects over 20,000 products and tens of thousands of CVEs with authenticated scanning that catches what surface-level tools miss, and RBAC plus role-based reporting let security generalists delegate tasks without handing out admin access. Skip this if your primary need is web application scanning; the infrastructure focus is strong, but the web scanning is secondary to the core network and data center mission.
