API Penetration Testing
APIs are the backbone of modern applications—connecting web platforms, mobile apps, cloud services, and third-party integrations. They are also one of the most targeted and frequently abused attack surfaces in today’s threat landscape. At F9 Infotech, our API Penetration Testing services identify, exploit, and validate security weaknesses within your APIs through realistic, manual attack simulation before attackers find them first.
We simulate real-world attacks against your APIs to uncover vulnerabilities that automated tools consistently overlook. Our assessments cover:
- Broken object-level and function-level authorization flaws
- Authentication bypass, token abuse, and privilege escalation
- Business logic abuse and rate-limit bypass scenarios
- Excessive data exposure and mass assignment vulnerabilities
- Backend system compromise via API attack chains
