Source Code Review
Our specialists read through your source code to find the security flaws hidden in the logic, uncovering the vulnerabilities that black-box testing misses and showing your developers the exact lines that need to change.
We read the code to find flaws at the source
Testing an application from the outside can only reveal so much. By reviewing your source code directly, we trace how data flows through your app and find the insecure patterns, missed checks and dangerous logic that outside testing cannot see.
Injection Points
Places where untrusted input reaches queries, commands or templates without proper handling.
Access Control Logic
Authorisation checks that are missing, inconsistent or easy to bypass in the code path.
Secrets & Keys
Hard-coded passwords, API keys and tokens committed into the codebase and its history.
Crypto & Data Handling
Weak algorithms, poor randomness and unsafe handling of sensitive data in memory and storage.
Insecure Patterns
Dangerous functions, unsafe deserialisation and error handling that leaks internal detail.
Third-Party Components
Vulnerable and outdated libraries pulled in as dependencies across your project.
The Deepest Flaws Live In The Code. That Is Where We Look.
Some of the most serious vulnerabilities never appear from the outside. They sit in a missed authorisation check, an unsafe way of building a query, or a secret committed to the repository years ago. Black-box testing can only guess at what the code is doing. Reading the source removes the guesswork and shows exactly where the risk lives and why.
Our team combines careful manual review with static analysis tooling, tracing input from where it enters your application to where it is used. We focus effort on the code that handles authentication, data and money. You get findings tied to specific files and line numbers, a clear explanation of the impact, and practical guidance your developers can apply straight away.
Standards and Frameworks We Review Against
- Every review is guided by the OWASP Code Review Guide and the OWASP Application Security Verification Standard (ASVS) for structured, repeatable coverage.
- We classify findings using the Common Weakness Enumeration (CWE) and the CWE / SANS Top 25, so your team can see how each issue relates to known weakness categories.
- Where relevant, we map results to compliance obligations such as PCI DSS, connecting a code-level fix to the standards your business is measured against.
Aligned to the frameworks that matter
Our testing follows the methodologies that set the global standard for application security.
