Security Analysis
Cursor security strengths: Multiple model selection lets you choose the most security-conscious model. Broader context awareness leads to more consistent security patterns. Custom rules via .cursorrules enforce project-specific security requirements.
Copilot security strengths: Integrated with GitHub Advanced Security (code scanning, secret scanning, Dependabot). Vulnerability filter blocks known insecure patterns. Deep integration with GitHub’s security ecosystem provides automated dependency updates and security alerts.
Common weaknesses: Both generate code with SQL injection, XSS, missing auth checks, and hardcoded secrets. Neither replaces dedicated security testing.
Verdict
For security, Copilot has the edge in ecosystem integration – pairing with GitHub Advanced Security creates a comprehensive security workflow. Cursor offers more flexibility with model choice and deeper context. Choose Cursor for AI coding power; choose Copilot for GitHub ecosystem integration. Use either with security scanning.
