API Security Assessment
Deep API testing to prevent data leaks, privilege escalation and abuse of backend interfaces.
Why companies need API assessments
Who should get this
Key benefits
Identify broken auth/authorization and mass assignment
Detect excessive data exposure and insufficient filtering
Prevent automation abuse and rate-limiting bypass
Improve API contract security (OpenAPI/GraphQL) and CI checks
Actionable PoC and prioritized remediation
Scope — What we test
Methodology
- API inventory & spec analysis (OpenAPI, Swagger, GraphQL schemas)

Common questions we hear before starting an assessment — click a question to reveal a short, clear answer.
Small apps: 1–5 days. Medium: 5–10 days. Complex systems: custom timeline.
We avoid destructive checks in production and schedule high-risk tests in staging when possible.
No — blackbox tests work. Source access enables deeper code review.
Yes — PoCs, prioritized fixes and developer-focused guidance are included.
Yes — retest packages validate fixes.
Executive summary, prioritized findings, PoCs and workshop walkthroughs.
Yes — mutual NDAs and secure report distribution are standard.
Yes — we can reverse-engineer GraphQL endpoints and fuzz schemas to find exposures.
Yes — we use secure tunnels, staging environments, or on-premise engagements as required.
We can help harden OpenAPI/GraphQL specs and add security checks into CI.
