What Is ZeroSSL?
ZeroSSL issues single-domain, multi-domain and wildcard certificates, validated by email, file upload or CNAME, with renewal handled through the ACME protocol or its SSL REST API. A management console tracks certificates, and SSL Monitoring checks installations. The site is operated by HID Global, part of ASSA ABLOY, and pitches ZeroSSL as an option between Let's Encrypt and traditional certificate vendors.
