This is for you if any of these ring true.
What you get from a code review.
We go beyond scanning. Our secure code review services analyse your code the way an attacker would, as one part of our broader cyber security services: finding logic gaps and validating trust boundaries.
Business logic, authorization, and trust boundaries automated tools miss.
Business logicAuthorizationAPI designTrust validation
We trace how your code behaves under real scenarios, not just how it's written, following data flows across services and validating authorization at every step. Payment flows get the same scrutiny, the kind of payment gateway security work we do for fintech clients.
Authentication, data validation, and REST security tested by hand.
AuthenticationData validationMicroservicesREST security
We test whether your services validate incoming requests, whether authentication holds across boundaries, and whether privilege escalation is possible through a weak endpoint, the kind of fintech API failure causes we've written about before.
Access rules confirmed to hold up under real edge cases.
RBAC validationSession securityIdentity checksPrivilege control
We confirm your access rules hold up under edge cases, and that privilege escalation isn't possible through parameter tampering or a logic bypass.
We stay on until the vulnerability is actually closed.
Fix guidanceSecure codingRe-reviewCompliance validation
We explain every finding, guide your team on the fix, and re-review afterward to confirm the vulnerability is actually closed, not just marked done.
Strategy & Innovation, our practice for security decisions made before they become a crisis.
Built for every vertical.
Why teams pick us for this.
Automated tools catch known patterns. Our reviewers think like attackers, testing the authorization logic tools never question.
We verify every finding before reporting and prioritise by impact, so your team acts on real risk instead of chasing false alarms.
We work inside your existing pipeline, so developers get feedback before merging rather than cleanup after a scramble.
Because we ship products ourselves, our findings come with fixes that fit how real systems are built, not generic advice.

Schedule a code review{ 01 }· Week 1
We map your codebase, flag the highest-risk areas such as APIs, authorization, and financial logic, and scope the review to where the risk actually is.
{ 02 }· Week 2 to 3
We trace authorization logic, validate data flows, and test API assumptions by hand, checking whether your code behaves as intended, not just as written.
{ 03 }· Week 3 to 4
You get a report organised by business impact, not CVSS score, with evidence and clear remediation steps your team can act on immediately.
{ 04 }· Ongoing
Your team implements fixes. We validate that each one actually closes the vulnerability, then re-review to confirm your code has improved.

Ways to work with us.
The same senior team and the same way of working, shaped to how much you already have in-house. Most clients start with one and move between them as they grow.
A scoped piece of work with a clear deliverable, timeline, and price. Best when the definition of done is clear.
A senior pod embedded in your tools and rituals, shipping every sprint. Best when you want capacity without a long hiring cycle.
Questions, answered.
A targeted review typically takes two to four weeks depending on codebase size. A small API can be reviewed in one to two weeks, while a large platform with several microservices takes three to four. We scope this upfront so the timeline is clear before we start.
Both. We review new code before it merges to catch issues early, and we audit existing systems to uncover risk that has built up over time. Most clients run continuous review for new code alongside periodic audits of legacy systems.
We notify your team immediately and document the finding with evidence rather than waiting for the final report. Your team prioritises the fix, and once it's remediated, we re-review to confirm the issue is actually closed.
Automated tools find known vulnerabilities in known places, such as a flagged SQL injection. Manual review finds the authorization bypass that lets any user reach another customer's data. Scanning detects; secure code review validates.
It helps directly. Auditors increasingly expect evidence that access controls and data handling actually work in code, not just on paper. A secure code review gives you that evidence, and the chance to fix gaps before an external team finds them.
