API Security

Your APIs Are Exposed. Most Businesses Don't Realise Until It's Too Late.

We test your REST and GraphQL APIs for the vulnerabilities that lead to data breaches, unauthorised access, and service disruption.

Overview

APIs power everything - your mobile app, your integrations, your SaaS platform, your internal tools. They're also the most attacked surface in modern applications. Unlike web pages, APIs don't have a visible UI, which makes vulnerabilities harder to spot and easier to exploit at scale. The OWASP API Security Top 10 exists for a reason - most APIs we test fail on at least 3 of the 10 categories.

What We Cover

Authentication & Authorisation

Broken Object Level Authorisation (BOLA), weak token handling, broken function-level authorisation.

Data Exposure

Excessive data exposure in responses, mass assignment vulnerabilities.

Input & Injection

SQL/NoSQL injection, command injection, SSRF.

Rate Limiting & Abuse

Missing rate limiting, resource exhaustion, lack of pagination.

GraphQL-Specific

Introspection in production, query depth/complexity attacks, field-level authorisation bypass.

Example Engagement

A fintech startup asked us to test their payment processing API before going live. We found a critical Broken Object Level Authorisation issue letting any user view any other user's transaction history, missing rate limiting on the OTP endpoint allowing brute-force in under 15 minutes, and excessive data exposure on the /api/users/me endpoint. All three were fixed within a week and the API launched on schedule.
