Secure Source Code Review

Some vulnerabilities stay invisible to external testing: hardcoded credentials, weak cryptography, rarely executed code paths. Code-level review exposes these issues along with their root cause.

Catching flaws during development is generally faster and less costly than fixing them in production.

• Input validation and injection flaws (SQL, command, template injection and more).
• Authentication, session and authorization logic.
• Cryptography usage and secrets (passwords, API keys) left in code.
• Error handling and logging, including sensitive data written to logs.
• Third-party libraries with known vulnerabilities (software composition analysis).
• Insecure configuration and leftover debug code.

We map findings to the OWASP Top 10:2025 and CWE (Common Weakness Enumeration). Where useful, we apply OWASP ASVS requirements as a checklist.

1. Scoping: Languages, frameworks, modules and critical workflows are defined.
2. Automated analysis: Static analysis (SAST) and dependency scanning are performed.
3. Manual review: Critical flows are reviewed line by line and tool findings are validated.
4. Reporting: Each issue includes file and line references, severity and a sample fix.
5. Verification: Fixed code is reviewed again.

Organizations building their own software, buyers who want security assurance before procurement, and owners of applications handling card or personal data. Combined with a penetration test (white box), it delivers the most complete coverage.

• Executive summary and risk distribution.
• Validated findings with file/line references, CWE mapping and severity.
• Sample fix code or approach for developers.
• List of vulnerable dependencies with upgrade guidance.
• Post-fix verification report.
