Source Code Security Review

Manual, expert-led security review of application source code — finding the design and implementation flaws that runtime testing cannot reach.

Why Source-Level Review

Some classes of vulnerability are practically invisible to runtime testing: race conditions, time-of-check-to-time-of-use defects, cryptographic algorithm misuse, business logic flaws that depend on internal state, and pre-authentication code paths gated behind narrow input conditions. A source code review reads the code with adversarial intent and finds them.

Engagement Scope

  • Threat-modelled scoping — review effort concentrated on the components carrying the greatest residual risk
  • Manual code review by senior application security engineers in the relevant language
  • Tool-assisted coverage — SAST findings triaged, false-positives discarded, true-positives confirmed
  • Dependency review — software composition analysis, transitive vulnerability inheritance, licence risk
  • Cryptographic review — algorithm selection, mode of operation, key handling, RNG usage
  • Authentication and authorisation logic review
  • Input handling and output encoding review
  • Configuration and secrets handling review
