Secure Code Review · Derry
Secure Code Review in Derry
Secure code review for Derry organisations, where the value is in the flaws a scanner cannot recognise. Automated tools find known patterns competently; what they cannot see is business logic — a discount applied twice, a workflow step skipped, an ownership check that happens after the action rather than before.
Why this comes up
The problem
Static analysis reports nothing significant and the checkout can be manipulated to reduce the price.
What you get
What we deliver
- Business logic examined against how the application is meant to behave
- Authorisation checks traced to confirm they occur before the action, not after
- Automated findings triaged so genuine issues are separated from noise
- Trust boundaries identified, particularly where client input is relied upon
- Cryptographic and secret handling reviewed rather than assumed correct
- Findings prioritised by exploitability instead of by tool severity rating

Secure Code Review in Derry — common questions
- What do scanners miss?
- Anything requiring knowledge of intent. A tool can spot an unsanitised query; it cannot know that applying a voucher twice should be impossible, or that a status transition ought to require approval — because those rules exist in your business rather than in the code's shape.
- Is static analysis worth running?
- Yes, as a complement rather than a substitute. It covers known patterns cheaply and continuously, which frees a review to concentrate on logic — the problem is treating a clean scan as an assurance rather than as one input among several.
- How is a review scoped?
- Around what would hurt most. Reviewing an entire codebase is rarely affordable, so concentrating on authentication, authorisation, payment handling and anything processing untrusted input produces considerably more value than an even sweep.
- Why prioritise by exploitability?
- Because tool severity ratings are context-free. A high-rated finding in code no user can reach matters less than a moderate one in the payment path, and a report ordered by real exploitability is one a development team can work through sensibly.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
