Our work with Internet security extends well beyond TLS certificates. Our sibling project, @ProssimoISRG, works to provide critical parts of the Internet with memory safe alternatives. Give them a follow to stay updated on their progress!

Our work is 100% funded by charitable contributions. That means every time you visit a website using Let's Encrypt (and there are 340 million to pick from), your security and privacy was made possible by generosity (and a bit of technical innovation). buff.ly/2KCZCUO
