Source Code Review Providers
Source code review (also known as secure code review or code audit) is a systematic examination of an application's source code to identify security vulnerabilities, coding errors, and deviations from secure coding practices. Manual code review by experienced security engineers is combined with static application security testing (SAST) tools to analyse code for vulnerabilities including injection flaws, authentication weaknesses, cryptographic errors, insecure data handling, race conditions, and logic flaws.
Code review covers multiple programming languages and frameworks, examining both custom code and the use of third-party libraries and dependencies. This white-box approach finds vulnerabilities that black-box testing cannot detect, such as backdoors, insecure cryptographic implementations, and subtle logic errors.
Source code review is particularly valuable during the software development lifecycle (SDLC) as it allows vulnerabilities to be identified and fixed early, when remediation costs are lowest. It is recommended by compliance frameworks including PCI DSS, SOC 2, and NIST, and is essential for organisations developing security-critical applications, financial systems, healthcare platforms, and government software.

Source Code Review FAQs
What programming languages can be reviewed?+
Professional code reviewers typically cover Java, C#, Python, JavaScript/TypeScript, Go, Ruby, PHP, C/C++, Swift, Kotlin, and other common languages. Specialist reviewers may cover embedded systems languages and proprietary platforms.
How is source code review different from automated SAST?+
Automated SAST tools find common patterns but produce false positives and miss complex logic flaws. Manual review by experienced engineers finds subtle vulnerabilities, validates automated findings, and assesses overall code quality.
How long does a source code review take?+
Duration depends on codebase size, complexity, and languages used. A focused review of critical components typically takes 5-15 days. Full application reviews of large codebases may take several weeks.
