Security Audit

A security audit examines your application for common vulnerabilities: exposed secrets in environment variables, SQL injection in database queries, cross-site scripting (XSS) in user-rendered content, missing authentication on API routes, and outdated dependencies with known exploits.

Automated tools handle the first pass: npm audit checks dependencies, secret scanners check for leaked API keys, and static analysis tools flag insecure patterns. Manual review covers business logic issues that automated tools miss, like authorization bypass or insecure direct object references (IDOR).

For vibe coders, security auditing is especially important because AI-generated code sometimes introduces vulnerabilities. AI might use string concatenation in a SQL query instead of parameterized queries, or render user input without sanitization. Running a security checklist after every major feature addition catches these issues early.
