Secure code review

Review the code paths
scanners miss.

Focused review of authentication, authorization, payment, data handling, cryptography, and high risk modules.

authpayment flowscryptodata handling

We read the code that decides who gets in, who can act, and how money and sensitive data move through your product. Static tools flag patterns; they cannot reason about intent. We follow the real logic across boundaries and prove where the implementation disagrees with what you meant it to do.

What we actually review

A linter tells you a variable is unused. It cannot tell you that an authorization check runs after the mutation, that a payment amount is trusted from the client, or that a token is signed with a key that never rotates. That is the work.

  • Authentication and session logic: login, reset, MFA, token issuance, lifecycle and revocation
  • Authorization: object level checks, role boundaries, and the places an access check is missing or too late
  • Payment and billing flows: amount trust, idempotency, replay, coupon and refund abuse paths
  • Data handling: what is stored, logged, exported and exposed, and how sensitive fields move
  • Cryptography: key management, signing, encryption at rest and in transit, and weak or homemade primitives

What you get

  • Live findings the moment we confirm them, not a PDF weeks later
  • Exploitable risk ranked by real impact, with the exact file and line, so you fix what matters first
  • Remediation guidance your engineers can ship, written to reduce ambiguity, not a generic reference link
  • Free retest and verified closure once the fix is deployed
  • An auditor ready report mapped to SOC 2, ISO 27001 and customer security reviews

How the engagement runs

You buy a pool of testing hours and spend them where the risk is, across this and your other surfaces. We scope the modules that matter, read them by hand, confirm each issue against running code, surface findings live, prioritize by impact, report for each audience, and retest until closure is proven. The outcome: less remediation ambiguity, and your critical product flows made safe.
