I provide comprehensive API penetration testing to evaluate how your backend services can be abused when trusted assumptions break.
APIs are the backbone of modern applications and the primary target for attackers because they expose direct access to business logic data and automation at scale. My testing focuses on how APIs behave under adversarial conditions not just whether endpoints respond correctly.
What I Test
Authentication mechanisms including tokens keys and OAuth flows
Authorization and object level access control
Insecure direct object references and mass assignment
Business logic abuse and workflow manipulation
Input validation and injection risks
Rate limiting and abuse scenarios
Undocumented and deprecated endpoints
Error handling and information disclosure
Testing is aligned with the OWASP API Security Top 10 and real world exploitation patterns.
Methodology
Understanding API purpose data flows and trust boundaries
Manual request manipulation and parameter tampering
Chaining authorization and logic flaws for impact
Validation of exploitability and real business risk
Controlled testing to protect production stability
I test APIs the way attackers do directly and at scale.
Deliverables
Executive ready report with clear risk assessment
Technical findings with reproducible request response evidence
Impact based severity prioritization
Actionable remediation guidance for backend teams
Optional retesting to validate fixes
Who This Is For
Organizations exposing public or partner APIs
Enterprises relying on microservices architectures
SaaS platforms with complex authorization models
Security teams seeking assurance beyond schema validation
Value You Get
Reduced risk of data exposure and automation abuse
Clear visibility into real attack paths
Findings developers can immediately act on
Security confidence in critical backend systems
If your APIs control access to data money or business workflows
I help ensure they fail safely when tested like a real attacker would.
