Replit Security Guide

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 can scan your Replit deployment URL to identify missing security headers, exposed endpoints, and other configuration gaps.
