Is that possible? I’ve used Cloudflare on so many sites and every time I test using this checker: SSL Checker
It always displays this below, I’ve never once seen it display anything else.
I checked under Edge Certificates and you were right - it’s Let’s Encrypt. I check a handful of other sites we manage in the account and none of them mention a Certificate Authority.
It was the combined fact that Siteground use Let’s Encrypt and I’d never seen Cloudflare do so that led to me challenging it.
