Scope and Threat Modeling
Human-led
We define your attack surface, trust boundaries, and the most likely attacker goals before testing begins.
API Security
Penetration testing for REST and GraphQL APIs — finding the authorization failures and data exposure risks your development team doesn't know to look for
API vulnerabilities are behind some of the largest breaches in recent years. We test whether your authorization logic, object ownership controls, and tenant boundaries hold up against an attacker who deliberately misuses valid credentials.
Engagement Duration
4-8 business days
Primary Outcome
A complete risk picture of your API surface — each exploitable path documented with proof of impact, affected data objects, and specific remediation steps.
Human-led
We define your attack surface, trust boundaries, and the most likely attacker goals before testing begins.
AI-assisted
Automation expands coverage and surfaces anomalous patterns worth manual attention — no finding ships without human review.
Human-led
Every finding is manually reproduced and confirmed by a senior analyst before it appears in your report.
Collaborative
We provide developer-ready fix guidance and retest at no additional cost after your patch window closes.
BOLA/IDOR vulnerabilities that let authenticated users access other users' data
GraphQL introspection and query abuse exposing fields outside their intended audience
Rate-limiting gaps that enable credential stuffing, enumeration, and abuse at scale
Verbose error responses that hand attackers a roadmap to your data model
We test your API the way an attacker would — with valid credentials, systematically probing whether object ownership, role boundaries, and tenant isolation actually hold under adversarial use.
BOLA and function-level authorization abuse scenarios
Cross-tenant data access and boundary erosion checks
Token scope enforcement under replay and mutation
Ownership validation gaps in nested object relationships
We combine automated endpoint analysis with manual abuse scenario testing to find what's both technically exploitable and practically harmful to your business.
Mass assignment and structural parameter tampering
Rate-limit resistance under distributed request patterns
Verbose response leakage and metadata overexposure
GraphQL introspection, depth, and resolver abuse testing

Error/metadata handling
Severity and exploitability scored per endpoint, operation, and data object — so your team knows where to start.
Reproducible proof for every authorization failure and data exposure finding.
Concrete recommendations for middleware, schema, and handler-level hardening — not generic API security advice.
After you fix, we retest to confirm API vulnerabilities are fully resolved.
