API Testing

Your IT Security Partner

API Testing

APIs power the majority of modern applications, enabling systems to communicate and process data seamlessly.

However, they also introduce unique security  challenges that can expose sensitive information or allow attackers to directly target backend systems.

Our API penetration testing service identifies weaknesses that could enable unauthorised access, bypass authentication controls, or manipulate application logic. By combining automated scanning with in depth manual analysis, we assess your APIs against recognised standards such as the OWASP API Security Top 10 and replicate real-world attack scenarios.

This helps your organisation reduce risk, improve resilience, and maintain secure, reliable API driven services.

Key Features

Endpoint Discovery & Enumeration

We map all exposed API endpoints including hidden or undocumented ones to ensure no attack surface is overlooked during testing.

Input Validation & Data Integrity Testing

Our team thoroughly test how your API handles user input, ensuring it properly validates, sanitises, and protects against tampering or injection attacks.

Rate Limiting & Abuse Prevention Checks

We assess protections against brute force, credential stuffing, and high volume request abuse to ensure your API can withstand malicious automation.

Robust Token, Key & Session Security Analysis

We evaluate how securely your API manages tokens, API keys, and session mechanisms, ensuring they cannot be intercepted, reused, or manipulated by attackers.
