How secure are Replit Deployments?

Replit Deployments run in isolated containers with automatic HTTPS via TLS certificates managed by Replit. The deployment infrastructure handles basic network security and provides always-on hosting separate from the development environment. However, Replit Deployments do not include built-in rate limiting, Web Application Firewall protection, or Content Security Policy headers by default. Developers must implement these security measures within their application code. UNPWNED checks externally observable security-header, public-endpoint, rate-limit, and configuration signals on the submitted Replit deployment; internal controls require direct review.
