API Penetration Testing

The most exposed surface. Tested the deepest.

Specialized testing of REST, GraphQL, gRPC, and WebSocket APIs — focused on authentication, authorization, business logic, and data exposure.

Overview

What this covers.

APIs power your products and your partners. They are also the most exposed and most exploited surface in modern applications. We test against the OWASP API Security Top 10 and chain findings to demonstrate real-world risk — not just CVE-style noise.

Coverage

What we test.

Comprehensive coverage across the categories that matter — combined manual and tool-assisted testing.

01

OWASP API Top 10

BOLA, broken auth, excessive data exposure, mass assignment, SSRF.

02

Authorization

Role and tenant isolation, vertical and horizontal privilege escalation.

03

Schema & Contract

OpenAPI/GraphQL schema fuzzing, hidden endpoints, undocumented methods.

04

Rate Limiting

Abuse paths, credential stuffing resilience, enumeration controls.

05

Token Security

JWT/OAuth flaws, refresh logic, scope confusion, replay attacks.

06

Logic & Workflows

State-machine abuse, race conditions, idempotency, payment flows.

Methodology

How we run it.

A repeatable, well-documented process so your team always knows what's coming next.

01
Discovery

Endpoint enumeration, schema parsing, role and permission mapping.

02
Auth Testing

Token analysis, MFA bypass, OAuth flow review, session handling.

03
Authorization Matrix

Cross-tenant and cross-role access testing at every endpoint.

04
Logic Abuse

Workflow misuse, race conditions, mass assignment, IDOR chains.

05
Report & Retest

Actionable findings, reproduction scripts, and free retest.

FAQ

Frequently asked.

Do you test GraphQL?+

Yes — including introspection abuse, depth/complexity attacks, batched query exploits, and authorization across resolvers.

Can you test without documentation?+

Yes. We enumerate endpoints and reconstruct schemas where docs are absent — though documented APIs are tested more thoroughly per unit time.
