API Security Testing

APIs are where the data lives. We test REST, GraphQL, gRPC and SOAP for the broken authorization, mass assignment, and rate-limit flaws that top the OWASP API Security Top 10.

What we test

Broken Object-Level Auth

BOLA/IDOR across every object and every role, the #1 API risk.

Broken Authentication

Token forgery, weak JWT, credential stuffing, and key leakage.

Mass Assignment

Over-permissive binding that lets attackers set fields they shouldn't.

Rate & Resource Limits

Unrestricted resource consumption, missing throttling, and cost/DoS abuse.

GraphQL-Specific

Introspection abuse, deeply nested queries, batching attacks, and field-level authz.

Schema-Aware Fuzzing

We ingest your OpenAPI/GraphQL schema to drive precise, high-coverage fuzzing.

How the engagement runs

1 · Scope & Rules of Engagement

We agree targets, timing, and constraints — with an NDA in place first.

2 · Recon & Mapping

We build a complete picture of the attack surface before touching a single exploit.

3 · Manual Exploitation

Hands-on testing and exploit chaining — the part scanners can't do.

4 · Reporting & Retest

Prioritized findings with reproduction steps, then a free retest of your fixes.

What you receive

  • Executive summary for leadership & stakeholders
  • Detailed technical findings with evidence
  • CVSS severity scoring & risk ratings
  • Clear, reproducible remediation guidance
  • Free retest of remediated issues
  • Attestation letter for clients / compliance

Frequently asked

Can you test with our API docs?

Absolutely — an OpenAPI/Swagger or GraphQL schema plus test credentials dramatically improves coverage and speed.

Which standard applies?

The OWASP API Security Top 10, complemented by PTES methodology and CVSS scoring.

Do you test internal/microservice APIs too?

Yes — internal service-to-service APIs are often the least protected and highest impact.
