Welcome to the new website for Internet Security Research Group (ISRG).
ISRG was created in 2013 to build and improve digital infrastructure for a more secure and privacy-respecting world. Our first project, Let’s Encrypt, is a free, automated, and open Certificate Authority that catalyzed widespread HTTPS adoption across the Web. Today, Let’s Encrypt secures more than 125 million websites.
While most of what ISRG does these days relates to Let’s Encrypt, we believe there will be other instances in which public benefit digital infrastructure can help to build, or improve access to, a better Internet. As such, there may be other ISRG initiatives in the future. We want ISRG to have its own home on the Web where we can communicate more broadly about security and privacy-related issues and projects.
ISRG is a 501©(3) that is fully supported through the generosity of those who share our vision for ubiquitous, open Internet security. If you’d like to support our work, please consider getting involved, donating, or encouraging your company to become a sponsor.
