Source code audit: find vulnerabilities before they reach production

We review your application's code with static analysis tools and expert manual review. We find everything from SQL injection to broken business logic, with enough context for your team to fix it.

The problem: automated tools don't understand context

SAST scanners generate a huge volume of false positives and don't understand your application's business logic. An expert reviewer can tell a real, exploitable vulnerability apart from a false positive, prioritize by real impact, and catch the design flaws no scanner can see: insecure direct object references, authentication bypasses, race conditions.

What we review

  • Injections: SQL, NoSQL, LDAP, OS command, XPath
  • Reflected, stored and DOM-based Cross-Site Scripting (XSS)
  • Broken access control and insecure direct object references (IDOR)
  • Authentication and session management flaws
  • Insecure deserialization and sensitive data exposure
  • Hardcoded secrets: API keys, passwords, tokens in the code
  • Vulnerable dependencies (Software Composition Analysis)
  • Broken business logic: payment flows, privileges, validation rules

How we run the review

  1. Automated static analysis: We run the code through SAST tools specialized for the stack (SonarQube, Semgrep, Bandit…). We cut out noise and prioritize findings.
  2. Risk-oriented manual review: We manually review the highest-impact paths: authentication, authorization, sensitive data and critical business logic.
  3. Dependency analysis: We audit the dependency tree (npm, pip, Maven…) against known vulnerability databases (NVD, GitHub Advisory).
  4. Triage and classification: Each finding is manually confirmed, classified by severity (CVSS) and documented with the vulnerable code snippet, impact and fix.
  5. Report and handoff session: We deliver the report and hold a session with the development team to answer questions and explain each vulnerability in context.

What you get

  • Technical report with vulnerable code snippets
  • Classification by severity (Critical / High / Medium / Low / Informational)
  • Recommendations with fixed code examples
  • Dependency analysis with associated CVEs
  • Executive report for non-technical stakeholders
  • Review session with the development team included

Who needs a source code audit?

  • SaaS startups before closing investment rounds or enterprise customer audits
  • E-commerce with critical payment, discount or stock management logic
  • Applications handling health, financial or personal data (GDPR)
  • Development teams that want to validate security before a major release
  • Companies that outsource development and want to audit the delivered code

Frequently asked questions

Do we have to give you access to the repository?

Yes, we need read access to the repository. We sign an NDA beforehand and all access is documented. You can create a dedicated branch or fork for the review if your policy requires it.

Which languages and frameworks do you support?

JavaScript/TypeScript (Node.js, React, Angular, Vue), Python (Django, FastAPI, Flask), Java (Spring), PHP (Laravel), Ruby (Rails), Go and .NET (C#). If you work with another stack, ask us.

How long does it take?

Between 3 and 8 business days depending on the codebase size. A 30,000-line project can be reviewed in about 4 days. Larger projects require more time or a review focused on critical modules.

Do you also review infrastructure as code (IaC)?

Yes. We review Terraform, CloudFormation, Kubernetes manifests and Dockerfiles to detect insecure configurations in infrastructure defined as code.
