Let’s Encrypt

You can’t build a secure website without having a certificate, and getting a certificate is one of the hardest parts of setting up a secure website. Mozilla helped start up Let’s Encrypt to make getting a certificate easier and promote the security of the Web. In 16 months, Let’s Encrypt went from an idea to the 3rd largest Certificate Authority on the Web. In this talk, we will discuss the challenges, decisions, and trade-offs that occurred along the way.

Mozilla Security

The Web is arguably the single largest platform for applications in the world. Securing a Web browser requires security expertise from across the field, including low-level program internals, network security, language design, and access controls. In this talk, we will discuss some of the critical Web security problems that we are working on at Mozilla, and some of the ways that academics can collaborate with us to help solve these problems.
