What is ACME?

ACME (Automated Certificate Management Environment) is an open protocol that empowers servers to request and manage SSL/TLS certificates directly from a Certificate Authority (CA). It fully automates the entire lifecycle—including Domain Validation (DV), Organization Validation (OV), issuance, renewal, installation, and revocation—completely removing the need for human intervention.

With ACME, your server handles the certificate workflow natively. There is no need to manually generate CSRs, upload validation files, or keep track of expiration dates. Instead, the server communicates with the CA over HTTPS using signed JSON requests. To prove domain ownership, the server automatically responds to a challenge (typically via HTTP or DNS). Once verified, the certificate is issued and deployed instantly.

Today, ACME is recognized as an official internet standard under RFC 8555 and is supported by major Certificate Authorities, including Sectigo. Its latest iteration, ACME v2, introduced support for wildcard domains, enhanced domain validation, and tighter security checks. This makes ACME SSL certificates the ideal choice for teams running uptime-critical applications, managing multi-server environments, or automating deployments at scale.
