We're talking with Josh Aas, the Executive Director of the Internet Security Research Group, which is the legal entity behind the Let's Encrypt certificate authority. In June of 2017, Let’s Encrypt celebrated 100 Million certificates issued. Now, just about 2.5 years later, that number has grown to 1 Billion and 200 Million websites served. We talk with Josh about his journey and what it's taken to build and grow Let's Encrypt to enable a secure by default internet for everyone.
