API Penetration Testing
We test your application programming interfaces (APIs) — which allow different software
systems
to talk to each other — for flaws like data leaks, broken authentication, and injection
attacks. This ensures your backend systems remain secure.

APIs power modern applications—but they also expand your attack surface. As attackers increasingly target APIs to gain unauthorized access or exfiltrate sensitive data, securing these interfaces has become essential for any web or mobile application.
Our API Penetration Testing service emulates real-world attack scenarios using manual techniques and industry-leading tools to uncover authentication flaws, improper object-level controls, and business logic vulnerabilities. We follow the latest OWASP API Security Top 10 (2023) guidelines to ensure maximum coverage and reliability.
What’s Included:
- OWASP Top 10 API Security Risks Coverage (2023) Test for critical issues like BOLA (Broken Object-Level Authorization), Broken Authentication, Excessive Data Exposure, and Security Misconfigurations.
- Authentication & Authorization Testing Validate token integrity (e.g., JWT), assess permission boundaries, and test for privilege escalation.
- Input Validation & Injection Testing Simulate injection attacks including SQL, NoSQL, command injection, and parameter tampering.
- Rate Limiting, Replay, & Abuse Simulation Check your API for lack of throttling, mass assignment, and replay attacks.
- Automated & Manual Testing Approach Tools used include: Postman, Burp Suite Pro, OWASP ZAP, jwt_tool, ffuf, Curl, and Kiterunner.
Trend-Focused Testing Includes:
- Business Logic FlawsValidate API endpoints for misuses that can break the workflow or create financial/data risks.
- Third-Party API MisuseAssess integrations and dependencies that may introduce indirect attack vectors.
- Cloud API Exposure Checks Identify insecure endpoints tied to cloud platforms (e.g., AWS, GCP, Azure).
Deliverables:
- Professionally designed report with PoC (proof of concept), technical findings, and remediation steps
- CVSS scoring for each vulnerability and a prioritized roadmap to secure your API
- Executive summary tailored for non-technical leadership
