Code Audit Services in 2026: What a Real Technical Assessment Covers and What It Costs

Key takeaways from the blog

A code audit is a health assessment across architecture, security, performance, maintainability, tests, and dependencies – not a targeted bug hunt.
Order an audit before acquisition due diligence, before hiring a new team, before major expansion, when weighing refactor vs. rebuild, or after a security incident.
The deliverable is a severity-ranked findings report with remediation recommendations, not a pass/fail grade.
Enterprise audits with compliance mapping (HIPAA, PCI-DSS, SOC 2) take longer and cost more than a focused security review.

My CTO said we needed a code audit. I asked how much and what we get. He said it depends. So I learned what a code audit actually covers – so the next time an engineer says “we need an audit,” I can have the conversation as an equal.

Quick Answer

Code audits cost $15,000–$80,000 and take 2–6 weeks. Focused security audit: $15K–$30K. Comprehensive audit (architecture, security, performance, maintainability, tests, dependencies): $30K–$60K. Enterprise audit with compliance mapping (HIPAA, PCI-DSS, SOC 2): $50K–$80K+.

Key Facts

A code audit reviews architecture, security, performance, maintainability, test coverage, and dependency health – not a bug hunt, a health assessment.
OWASP Top 10 is the standard vulnerability taxonomy for security audits.
Average Node.js project has 300+ transitive dependencies – any may contain known CVEs.
The deliverable: prioritized findings by severity (critical/high/medium/low) with remediation recommendations.

When to Order an Audit

Before acquiring a company (due diligence). Before hiring a new engineering team. Before major feature expansion. When evaluating refactor vs. rebuild. After a security incident.

Cost Table

Audit Type	Cost	Timeline
Focused security audit	$15K–$30K	2–3 weeks
Comprehensive code audit	$30K–$60K	3–5 weeks
Enterprise with compliance	$50K–$80K+	4–6 weeks
Penetration testing add-on	+$15K–$40K	+1–3 weeks
