Manual Source Code Security Audit & Vulnerability Triage

Deep, line-by-line code evaluation to uncover logic flaws and architectural flaws before production deployment.

An exhaustive manual examination of critical application codebases, focusing on business logic bypasses, complex authorization failures, cryptographic misconfigurations, and data handling vulnerabilities that automated tools miss.

Step-by-Step Engagement Stages

A transparent, predictable process ensuring minimal developer disruption and maximum remediation clarity.

01

Scoping & Threat Profiling

We establish the review perimeter, identify trust boundaries, review data schemas, and execute mutual non-disclosure agreements with defined repository access parameters.

02

Manual Deep-Dive Inspection

Our senior code auditors trace execution paths across backend logic, state machines, token verification flows, and third-party library integrations.

03

PoC Formulation & Risk Assessment

Every candidate issue is manually verified against reproducible scenarios to eliminate false positives and calculate realistic business impact.

04

Remediation Guide & Engineering Handover

We deliver a comprehensive report paired with code-level fix guidance and conduct a live technical walkthrough with your development leads.

05

Post-Remediation Re-Audit

Once your developers deploy fixes, we perform a targeted re-review of the updated commits to confirm vulnerability closure.
