API Penetration Testing in Stoke-on-Trent
API penetration testing for Stoke-on-Trent organisations, where the failures are almost always about authorisation rather than authentication. Signing in works correctly; what breaks is one authenticated user reaching another's records by changing an identifier — and no automated scanner finds that, because it has no way of knowing who should see what.
Why this comes up
The problem
Changing an identifier in a request returns another customer's data to an authenticated user.
What you get
What we deliver
- Object-level authorisation tested with multiple accounts and real identifiers
- Function-level access checked, since privileged endpoints are frequently unprotected
- Documentation used to find endpoints, and undocumented ones sought separately
- Mass assignment probed, as APIs often accept fields they should ignore
- Rate limiting and resource consumption assessed at the endpoint level
- Findings demonstrated with reproducible requests rather than described abstractly

API Penetration Testing in Stoke-on-Trent — common questions
- Why can scanners not find these issues?
- Because they require knowing the intended rules. A tool sees a request succeed and cannot tell whether that user was entitled to the record returned, so authorisation flaws need a tester with two accounts and an understanding of what each should reach.
- What is mass assignment?
- An endpoint accepting fields it should not. A profile update that quietly honours a role or account-status field lets a user grant themselves privileges through an ordinary request, and it is common in APIs that bind request bodies directly to models.
- Should undocumented endpoints be tested?
- Particularly those. Documentation describes the intended surface; older versions, internal endpoints and routes left from previous features frequently remain reachable and unprotected, and they are exactly what an attacker enumerating your API will find.
- How should findings be delivered?
- As requests your developers can replay. An abstract description of an authorisation flaw invites disagreement about severity, whereas a reproducible request returning data the account should not see is unambiguous and considerably faster to act on — and it gives the team a way to confirm the fix themselves.
- Do you work with businesses across Staffordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Stoke-on-Trent and the surrounding Staffordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Stoke-on-Trent businesses do you usually work with?
- Multi-site stock, ordering and networking for businesses operating across several town centres, plus ceramics ecommerce. Beyond that we work across Ceramics, Manufacturing, Logistics, Retail and Digital.
- Do you cover the areas around Stoke-on-Trent?
- Yes — we work throughout West Midlands, including Birmingham, Manchester, Lichfield. Stoke-on-Trent is an urban area of roughly 260,000+, and we take on work across the wider Staffordshire region rather than the city boundary alone.
