Netlify has been using Let’s Encrypt to provide free HTTPS for its customers since 2016, aiming to make the secure web more accessible. The company recently migrated from ACME v1 API endpoint to v2, introducing wildcard domain support, which was a long-requested feature by both Netlify and its customers. This migration allowed for the introduction of wildcard domain certificates, making it easier to manage multiple subdomains with a single certificate. Despite some challenges, such as hitting Let’s Encrypt's 300 new orders per account limit, Netlify successfully implemented this feature, reducing support cases related to SSL/TLS certificates by more than half. The company is now working towards its goal of providing HTTPS for all sites hosted on Netlify, thanks in part to the support of Let’s Encrypt and ACME v2.
