A code audit is most valuable before problems surface, not after. The clearest triggers include:
- Before an acquisition or investment round: so you find and fix problems before a buyer’s technical due diligence does.
- Before scaling: since architecture flaws that are manageable at low traffic often collapse under load.
- Before a compliance certification: (SOC 2, HIPAA, PCI DSS, ISO 27001).
- After inheriting a codebase: through an acquisition, staff turnover, or vendor handoff.
- Before a major product launch or release.
- When symptoms appear: slow deployments, unexplained bugs, or developer reluctance to touch certain modules.
- When software has been in production for years with no formal review.
The audits that provide the most value consistently happen before a crisis, not during one.
