API Security

Find the API weaknesses attackers look for first.

FaultLabs tests API authorization models, object-level access, authentication flows, rate limits, and data exposure risks across modern service architectures.

Typical coverage

API testing can be performed with documentation, collections, source context, or black-box access depending on your goals.

  • Broken object-level authorization
  • Excessive data exposure
  • Weak authentication and token handling
  • Mass assignment and unsafe object updates
  • GraphQL introspection and resolver abuse
