Our public stats pipeline used to take hours to run every day. Now it takes less than 10 seconds. ⚡⚡⚡ Let's Encrypt issues 6–10 million certificates every day so our logs keep growing. Our old stats scripts broke more often than we’d like, and answering questions about our own issuance meant digging through raw logs by hand. So instead of fixing the old system again, we rebuilt it on ClickHouse. The outcomes have been positive! • Questions like "what's our issuance by profile over the last 180 days?" now return in milliseconds. • Finding affected certificates during an incident takes minutes instead of hours of engineering time. • Our rebuilt stats page makes it cheaper for us to provide stats to the public. Thanks to Lena Underwood from our team who wrote a blog post about how we did it.

Building a more secure and privacy-respecting Internet for everyone.
About us
Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. It is a service provided by the Internet Security Research Group (ISRG). We give people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, for free, in the most user-friendly way we can. We do this because we want to create a more secure and privacy-respecting Web. The key principles behind Let’s Encrypt are: Free: Anyone who owns a domain name can use Let’s Encrypt to obtain a trusted certificate at zero cost. Automatic: Software running on a web server can interact with Let’s Encrypt to painlessly obtain a certificate, securely configure it for use, and automatically take care of renewal. Secure: Let’s Encrypt will serve as a platform for advancing TLS security best practices, both on the CA side and by helping site operators properly secure their servers. Transparent: All certificates issued or revoked will be publicly recorded and available for anyone to inspect. Open: The automatic issuance and renewal protocol will be published as an open standard that others can adopt. Cooperative: Much like the underlying Internet protocols themselves, Let’s Encrypt is a joint effort to benefit the community, beyond the control of any one organization.

Thank you to everyone who donated and left comments telling us how much you appreciate our work during our Summer Campaign. We had fun sharing with the team anecdotes about donations that came in from all around the world! And we really do mean all around the world: donations came from 57 countries across six continents, from Tokyo to Berlin, São Paulo to Nairobi. Does anyone know someone in Antarctica? Let’s get full continental representation! It takes a community to sustain Internet-scale projects like Let's Encrypt. Thank you for being part of ours and for helping us build a better Internet. #LetsEncrypt #InternetSecurity #Nonprofit #AntarcticaRepresent

The Feisty Duck newsletter is always chock full of relevant information and insight about cryptography and security. We look forward to it every month but this one was especially exciting because there's a blurb about the last days of our summer fundraising campaign. It takes a community to support an Internet-scale project like Let's Encrypt so we appreciate Ivan Ristić and the Feisty Duck team along with every reader who decided to become a donor. Teamwork makes the dream (and Internet) work! 🙌

When Let's Encrypt started, 39% of page loads were encrypted. Today, in much of the world, it’s over 80%. Hundreds of millions of websites rely on Let’s Encrypt certificates every day. We put the "S" in HTTPS. Our first root certificate, “ISRG Root X1,” has become something billions of people depend on without even knowing it’s there. Learn more in this article, authored by yours truly. Donate $75 or more before August 31, and we’ll send you our limited-edition ISRG Root X1 shirt as a thank you. Link to donate in the comments. :)

Scott Helme has annually analyzed the top 1M websites for ten years. Thank you for that contribution toward our collective understanding of patterns and trends! This year, Scott’s report shows that 44% of the top 1M websites were using a post-quantum key exchange. It’s an important step in migrating to a more secure web in a PQ age. If you operate a server, make the switch! As our engineer Andrew Gabbitas noted recently, it’s one of the most high-leverage things you can do today. We’re looking forward to seeing much higher numbers in next year’s report!
