Frequently Asked Questions

1. When should a company conduct a code audit?

A code audit should be conducted before scaling a product, attracting investment, migrating to a new vendor, or launching a major release. These stages expose hidden risks in architecture, security, or performance. Early audits help prevent costly fixes later and provide a clear roadmap for stable growth.

2. What does a code audit actually include?

A code audit typically covers code quality, architecture structure, security vulnerabilities, performance bottlenecks, and infrastructure setup. Advanced vendors also review third-party integrations and CI/CD pipelines. The result is a prioritized report with actionable recommendations, not just a list of issues.

3. How do you choose the right code audit company?

You should select a vendor based on technical depth and industry expertise, as well as reporting clarity. A strong partner provides structured insights and understands compliance requirements in your domain. Clear communication and a practical improvement roadmap matter more than brand recognition alone.
