Why Source Code Review Matters
Source code vulnerabilities are the root cause of most security breaches. While penetration testing identifies vulnerabilities in running applications, source code review catches security flaws during development, when they're easiest and cheapest to fix. A single overlooked SQL injection, authentication bypass, or hardcoded credential can expose your entire organisation to catastrophic risks.
Modern codebases pull in hundreds of dependencies, move fast through CI/CD, and ship daily. Developers aren't writing insecure code on purpose, they just don't have time to think through every security implication. That's where a focused security review catches what normal development processes miss.
If you're going through SOC 2, PCI DSS, or ISO 27001 compliance, or if you're preparing for an acquisition or investor due diligence, a code review gives you documented evidence that your codebase has been examined by an independent security team. That carries weight that automated scan reports alone don't.
Our Review Methodology
We don't just point a SAST tool at your repo and hand you the output. Our consultants read your code, understand how your application works, and focus on the paths where real vulnerabilities live: authentication flows, payment logic, data handling, API boundaries, and anywhere user input touches a database or command.
Manual Security Code Review
We manually trace data flow through your critical code paths: authentication, authorisation, payment processing, data handling, and any custom business logic. This is where we find the vulnerabilities that SAST tools structurally cannot detect, like flawed state machines, race conditions, and authorisation logic that works for the happy path but breaks under edge cases.
Static Analysis (SAST)
We run automated static analysis across your entire codebase using tools like Semgrep, CodeQL, and commercial SAST platforms to catch known vulnerability patterns at scale. We also write custom rules tuned to your tech stack and application patterns, because off-the-shelf rulesets miss context-specific issues.
Dependency Analysis
Your application code might be solid, but if it pulls in a compromised or outdated dependency, none of that matters. We analyse your dependency tree for known CVEs, abandoned packages, malicious published versions, and transitive dependencies that introduce risk several layers deep.
Languages & Frameworks We Cover
Common Vulnerabilities We Identify
Injection Flaws
SQL injection, NoSQL injection, OS command injection, LDAP injection, and expression language injection

Weak algorithms, improper key management, predictable random values, insecure protocols
Data Exposure
Sensitive data in logs, insecure storage, insufficient encryption, cleartext transmission
Business Logic Flaws
Workflow bypasses, race conditions, insufficient validation, state management issues

Fix Vulnerabilities Early
Fixing a vulnerability in production costs significantly more than catching it during development. There's the incident response, the emergency patch, the customer notification, the compliance reporting. Code review shifts that discovery left, finding the problem when it's still just a code change instead of a security incident.
A pentest tells you your app is vulnerable. A code review tells your developers exactly why and exactly how to fix it.
