Cloudflare is enhancing API security by closing all HTTP ports on api.cloudflare.com, enforcing HTTPS-only connections. This significant move aims to eliminate vulnerabilities associated with cleartext HTTP traffic, where sensitive information like API tokens could be intercepted by malicious actors or network intermediaries. By mandating HTTPS-only connections, Cloudflare is setting a new standard in cybersecurity practices, protecting against potential data leaks and enhancing the overall security posture.

The decision to block unencrypted traffic to API endpoints is a strategic response to the increasing sophistication of cyber threats. Even with automatic redirection from HTTP to HTTPS, a window of vulnerability exists where sensitive data could be transmitted over unencrypted channels. Cloudflare's proactive approach rejects cleartext connections at the transport layer, safeguarding organizations relying on APIs and reducing the risk of cyber threats. This aligns with Cloudflare's efforts to support AI adoption with a security-first approach, ensuring reliable and safe use of AI technologies.
