API Penetration Testing
Every API endpoint is a potential entry point for your attacker
Protect your API endpoints against cyber threats, protect sensitive data, and ensure a secure communication channel between clients and servers.
Broken Authentication & Session Management (JWT, OAuth vulnerabilities)
API Injections (SQL, XML, JSON injection attacks)
Sensitive Data Exposure (unencrypted data transmission, weak encryption)
Improper Authorisation (access control vulnerabilities, IDOR)
Excessive Data Exposure (overexposing data in API responses)
Lack of Rate Limiting (DoS attacks via brute force)
Security Misconfiguration (default credentials, incorrect permissions)
Insecure Communication (no HTTPS, weak SSL/TLS configurations)
Broken Object Level Authorisation (insecure direct object references)
Insufficient Logging & Monitoring (failure to detect abnormal behaviour)

Hardening Your API Endpoints Using Proven Security Frameworks
We identify, analyse, and mitigate security vulnerabilities in both RESTful and SOAP APIs, based on industry-recognised standards such as OWASP API Security Top 10, OWASP API Security Testing, and NIST guidelines.
Our methodology combines manual techniques and automated tools to determine if an attacker can:
Bypass Mechanisms
Bypass authentication and authorisation mechanisms (JWT/OAuth flaws).
Perform Injection Attacks
Perform injection attacks (SQL, XML, command injections).
Expose Sensitive Data
Through weak encryption or misconfigurations.
Access Unauthorised Data
By exploiting broken access control (IDOR, business logic flaws).
Bypassing Rate Limits
Bypass rate-limiting or input validation to flood the API with requests.
Intercept API Traffic
Intercept API traffic through man-in-the-middle (MitM) attacks.
Exploit Insecure API Endpoints
Exploit insecure API endpoints for remote code execution or privilege escalation.
Actionable Recommendations You Can Bring To Stakeholders
We deliver comprehensive, cryptographically signed penetration testing reports that are both verifiable and tamper-proof. Each report includes detailed vulnerability backgrounds, clear impact assessments, and actionable recommendations. And because security is a global concern, our reports are available in 113 languages—ensuring your cross-border teams are always in the know.
Compliance Verification Reporting
The report clearly shows the specific standards the app complies to.
