Secure Code Review and Source Code Vulnerability Analysis

Weaknesses sit in the code. We read your source code, or the shipped build when no source is available, find the vulnerabilities, verify each one and engineer the fix into the code.

What we analyze

The review follows the code and what it does at runtime:

  • Source code of web, mobile and backend software.
  • Shipped builds, decompiled where needed, for hardcoded keys and credentials.
  • Third-party libraries and SDKs with their versions.
  • Authentication, authorization and cryptography in the code.
  • Data flows and trust boundaries.

From finding to fix

Agents cover the breadth and mark candidates. Specialists verify each one, explain how it could be abused and write the fix. You receive a change that your engineers can review, instead of a list of warnings.

What you receive

A written report with evidence, a CVSS severity and the fix for each finding, down to the affected code. We retest the fix. The report is technical evidence, not a certificate.

Evidence from audited software

The public ledger lists 387+ audited apps and 262+ critical findings. These full reports show how we document what we find:

  • SAP: A Chinese push SDK in a field-service app, and Firebase keys hardcoded across five apps.
  • Nike: Development and production push credentials hardcoded in the shipped build.
  • Strava: A hardcoded key and a security configuration that protects nothing.
  • Revolut: The largest third-party SDK in the series and what it sends to a US company.

Every other investigation is in the full evidence ledger.

Start with the Domain Security Test

The Domain Security Test examines one domain from the outside: read-only, from a European IP address, with no login and no payloads. A researcher reviews your request and replies within one business day.

Plans and prices are on the Access page, the agents behind every review on The Squad page.

Plans and prices are on Access, the agents behind every review on The Squad and the frameworks we measure against on Standards.

Domain Security Test
Quick Check

Put your domain to the test. Submit it for an initial external security assessment of your publicly accessible attack surface.

No login, no payloads and no changes to your systems.

A researcher reviews your request before testing begins and responds within one business day. You'll receive a short written report covering our findings, likely attack scenarios, potential financial impact and recommended next steps, alongside an exportable security intelligence graph connecting the findings.

Questions about secure code review

Do you need our source code?

We work with the material you send. A shipped build is enough for many findings, and source code allows a deeper review.

Which languages do you cover?

Our engineering investigations cover Python, Rust, Go, Java, JavaScript, TypeScript and mobile stacks.

Do you write the fix?

Yes. We engineer the fix down to the affected code and retest it.

What does it cost?

Plans and prices are on the Access page.
