Securing a Site With a Cloudflare Client Certificate and mTLS

Categories: Cloudflare | Security

When a website required limited access, I needed a way to lock it down to specific physical devices. I couldn't rely on IP addresses which might change regularly, and while a strong password requirement might be sufficient I wanted something a little more secure. Not to mention that it shouldn't be crawled by any search engines either. The solution was a Cloudflare client certificate and mTLS firewall rule.
