In June of 2017, Let’s Encrypt celebrated 100 Million certificates issued. Now, just about 2.5 years later, that number has grown to 1 billion. What’s changed since 2017?
In June of 2017 approximately 58% of page loads used HTTPS globally, 64% in the United States. Today 81% of page loads use HTTPS globally, and we’re at 91% in the United States! This is an incredible achievement. That’s a lot more privacy and security for everybody.
In June of 2017 we were serving approximately 46M websites, and we did so with 11 full time staff and an annual budget of $2.61M. Today we serve nearly 192M websites with 13 full time staff and an annual budget of approximately $3.35M.
