Let's Encrypt - 웹 도메인의 30%차지

 

The server you’re reading this on uses automated certs from Let’s Encrypt—they are more common on a domain than any other registrar! Over 47 million domains are protected with Let’s Encrypt certs, almost 30%.

Out of 352.3M domains, the dataset has 158.7M connections that proceeded far enough to provide a certificate with an issuer’s Distinguished Name. The top dozen1 are:

47.2M	Let’s Encrypt
28.9M	DigiCert
13.8M	Comodo
10.1M	Google
7.2M	GoDaddy
7.1M	Sectigo
7.0M	cPanel
6.1M	GlobalSign
3.4M	CloudFlare0
2.5M	Amazon
2.1M	(anonymous self-signed)
1.1M	Plesk

Let’s Encrypt certs expire after 3 months, which pushes a regular update cycle, but there are still a number of ancient security practices around the web today.
