How to Secure Your GitHub Copilot App
Last updated: January 12, 2026
GitHub Copilot accelerates development, but AI-generated code needs security review. This guide covers using Copilot securely.
Step-by-Step Security Guide
1. Review Security-Critical Suggestions
Never auto-accept Copilot suggestions for authentication, encryption, or database queries.
2. Never Put Secrets in Comments
Copilot uses comments as context. Never include real API keys or credentials in comments.
3. Configure Content Exclusions
Exclude sensitive files from Copilot context using content exclusion settings.
4. Use Security Linters
Run static analysis on Copilot-generated code to catch common vulnerabilities.
5. Use Established Security Libraries
For auth and crypto, use established libraries rather than Copilot-generated implementations.
6. Scan Deployed Applications
Run VAS on your deployed app to catch vulnerabilities in AI-generated code.
Common Security Mistakes
Avoid these common GitHub Copilot security pitfalls:
Recommended Security Tools
Use these tools to maintain security throughout development:
Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use VAS to verify your GitHub Copilot app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
Does GitHub store my code with Copilot?
Copilot sends code context for suggestions. GitHub claims not to use private code for training (Business/Enterprise). Check the current privacy policy for your subscription tier.
Can Copilot generate secure code?
Copilot can generate secure code but also insecure code. It optimizes for what looks plausible, not security. Always review security-critical suggestions.
