API security
testing.
APIs are the modern attack surface — and the hardest to inventory. We discover, document, and exhaustively test REST, GraphQL, gRPC, and SOAP services against the OWASP API Security Top 10.
You can’t defend what you can’t see.
Most breaches in the past five years have traced back to an API your security team didn’t know existed — a deprecated version, a mobile-only endpoint, an admin route in staging. We begin by building the API inventory you don’t have, then exhaustively test every surface.
Every role. Every tenant. Every verb. Every parameter. Mapped to the OWASP API Security Top 10 and delivered with reproducible PoCs and spec-level fixes.
Every category. Manually validated.
Direct object references, tenant bleed, and identifier enumeration across every resource.
Token lifecycle, refresh abuse, JWT flaws, MFA bypass, and credential stuffing resilience.
Mass assignment, excessive data exposure, and field-level access failures.
Rate limiting, quota enforcement, and abuse of expensive operations.
Horizontal and vertical privilege escalation through administrative or hidden endpoints.
Automation-driven abuse of signup, checkout, coupon, and workflow endpoints.
URL handling, internal service access, and metadata-endpoint exposure.
CORS, TLS, error handling, debug exposure, and insecure defaults.
Shadow APIs, deprecated versions, environment drift, and documentation gaps.
Supply-chain exposure from downstream services and SDKs.
Discover, enumerate, abuse, verify.
Discovery & Inventory
API catalog construction via docs, spec files (OpenAPI, GraphQL schema, protobuf), traffic capture, and active discovery — including shadow APIs.
Authenticated Role Matrix
Testing across every role, tenant, and scope — anonymous through admin — against the full OWASP API Security Top 10.
Abuse & Logic Testing
Business-logic abuse, workflow chaining, mass-assignment, race conditions, and GraphQL-specific attacks (introspection, batching, depth).
Reporting & Retest
Reproducible PoCs, developer-grade remediation, spec recommendations, and verified retest.
