API Security Assessment
APIs are where modern breaches happen: machine-to-machine, high-volume, and often under-tested. We probe every endpoint, method, and object reference for the broken authorization and logic flaws that dominate real-world API incidents.
What you walk away with
- Full coverage of the OWASP API Security Top 10
- Object- and function-level authorization tested at scale
- Token, OAuth, and JWT handling validated against abuse
Beyond the endpoint list
We ingest your OpenAPI, GraphQL schema, or WSDL, then go past documented behaviour to enumerate hidden methods, mass-assignment paths, and objects your clients were never meant to touch. Broken object-level authorization (BOLA) and broken function-level authorization are treated as first-class targets because they are where APIs actually fail.
What we test
- Broken object-level authorization (BOLA/IDOR) across every resource
- Broken authentication: token issuance, validation, expiry, and revocation
- OAuth 2.0 and OpenID Connect flow abuse and scope escalation
- JWT weaknesses: algorithm confusion, weak signing, and claim tampering
- Excessive data exposure and mass assignment
- Rate limiting, resource exhaustion, and business-logic abuse
- GraphQL-specific risks: introspection, batching, and query-depth attacks
Every protocol you run
REST, GraphQL, and SOAP each carry their own failure modes. We test them with protocol-aware tooling and hand-crafted requests, validating that authorization is enforced consistently no matter how the endpoint is reached.
