How does Cloudflare's security compare to ngrok when exposing a local development environment?

Cloudflare provides significantly stronger security. It includes DDoS protection, a WAF, bot management, and SSL/TLS encryption by default. ngrok offers some basic authentication and IP restrictions, but it's not as comprehensive as Cloudflare's security suite. Cloudflare's outbound-only connection model also reduces the attack surface compared to ngrok's inbound port exposure.
