Security FAQ

How secure is Supabase?

Short Answer

Supabase can be very secure when properly configured. The platform itself has strong security foundations, but your implementation determines actual security.

Detailed Answer

Supabase's security depends on two factors:

  1. **Platform Security**: Supabase's infrastructure is built with security in mind, using industry-standard practices and regular security audits.

2. **Your Configuration**: Most security issues come from misconfiguration, not platform vulnerabilities. You need to: - Configure database security rules - Keep secrets out of frontend code - Set up proper authentication - Add security headers

Bottom line: Supabase provides the tools for secure apps, but you must use them correctly. Scan your app to verify your configuration.
