Source Code Audit

Software vendors needing to guarantee code security to their clients, or organizations inheriting a codebase whose actual state nobody knows.

Last updated — August 22, 2026

The problem this solves

You ship software to clients who demand security guarantees on the code, or you inherit an existing codebase with no visibility into its flaws. Without a structured review, the most critical vulnerabilities — authentication, secrets management, injection flaws — stay invisible until they're exploited.

What's included

Automated static analysis of the source code

Manual review of critical points: authentication, authorization, cryptography

Manual review of session management and injection-related mechanisms

Dependency and software supply chain analysis

Review of secrets exposed in the code (keys, credentials, tokens)

Assessment of the team's secure development practices

Frameworks applied

OWASP ASVSOWASP SAMMCWE Top 25SLSA

Deliverables

—

Detailed technical report with evidence (code excerpts, exploitation paths)

—

Non-technical executive summary

—

Remediation plan prioritized by risk and effort

—

Post-fix counter-verification after identified gaps are corrected

Varies with codebase size and complexity, typically 5 to 12 days

Typical duration

Client prerequisites

  • Access to the full source code for the scope covered (repository, relevant version history)
  • Minimal technical documentation (architecture, dependencies, environments)
  • Availability of a reference developer to answer context questions
  • An isolated test environment if complementary dynamic validation is needed

Frequently asked questions

Does the audit cover all the code, line by line?

No. Automated static analysis covers the entire codebase supplied, but the manual review — the most time-intensive part — targets critical points (authentication, authorization, cryptography, session management, injection), not the full codebase.

Does the audit catch vulnerable dependencies?

Yes, the supply chain analysis identifies third-party libraries with known vulnerabilities or risky update practices.

What happens if secrets (API keys, credentials) are found exposed in the code?

They are flagged immediately, outside the normal reporting schedule, given the risk of immediate exploitation, before being folded into the final report.

Is read-only or write access to the repository required?

Read-only access to the source code and relevant history is sufficient to conduct the audit.

Does a source code audit replace a penetration test on the application?

No. The code audit examines the source directly and catches classes of vulnerabilities an external test may not necessarily surface; the penetration test validates the application's actual behavior under runtime conditions. The two are complementary.
