We're making it possible for everyone to experience a secure and privacy-respecting Web. We make it easy to get certificates for HTTPS, because ease of use is critical for adoption. We provide certificates free of charge, because cost excludes people. Our certificates are available in every country in the world, because the secure Web is for everyone. We strive to be open and transparent, because these values are essential for trust.
