Who runs Let's Encrypt
Let's Encrypt lencr.org
What’s lencr.org? lencr.org is a domain name owned by Let’s Encrypt. We use it to host data that is referenced inside the certificates we issue. Why is my computer fetching this data? Is it malicious? No, the data on lencr.org is never malicious. When a device connects to lencr.org, it’s because client software on that device (like a web browser or an app) connected to another site, saw a Let’s Encrypt certificate, and is trying to verify that it’s valid. This is routine for many clients.
