As of the end of July 2018, the Let’s Encrypt root, ISRG Root X1, is directly trusted by Microsoft products. Our root is now trusted by all major root programs, including Microsoft, Google, Apple, Mozilla, Oracle, and Blackberry. Today’s announcement that we’re trusted by all major root programs represents a major milestone for us, but it’s not the conclusion of our journey towards being directly trusted everywhere. Certificates from Let’s Encrypt have been widely trusted since our first issuance because of a cross-signature from another CA called IdenTrust. Browsers and operating systems have not, by default, directly trusted Let’s Encrypt certificates, but they trust IdenTrust, and IdenTrust trusts us, so we are trusted indirectly. IdenTrust is a critical partner in our effort to secure the Web, as they have allowed us to provide widely trusted certificates from day one. While Let’s Encrypt is now directly trusted by almost all newer versions of operating systems, browsers, and devices, there are still many older versions in the world that do not directly trust Let’s Encrypt. Some of those older systems will eventually be updated to trust Let’s Encrypt directly.
