Never Worry About Expiring SSLs Again - Automate Your Certificates with ACME

Managing SSL certificates shouldn’t be a hassle. With Sectigo ACME (Automatic Certificate Management Environment) automation, you can eliminate manual installations, reduce human error, and ensure your certificates never expire. After a one-time simple setup, your Sectigo ACME Certificate-as-a Service (CaaS) certificate will be automatically managed and renewed in the background – so you can focus on running your business, not managing security.

Whether you’re securing a single website or an entire network, Sectigo ACME Certificate-as-a Service (CaaS) integrates directly with your infrastructure using ACME provisioning. Sectigo ACME CaaS is compatible with Linux, Windows, Kubernetes, cPanel, Plesk, and major web servers—integrating seamlessly with any ACME client for end-to-end SSL automation.

Sectigo ACME Certificate-as-a-Service (CaaS): Fully Automated SSL Issuance, Renewal, and Installation

Sectigo ACME Certificate-as-a-Service (CaaS) is the new way to issue, install, and manage SSL certificates. Built to work with the industry-standard ACME (Automatic Certificate Management Environment) protocol, Sectigo ACME CaaS allows your servers to connect directly with Sectigo's Certificate Authority (CA) to automatically deploy as many certificates as needed to ensure your domain (website) always stays secure:

  • Fully automated. Completely eliminates the manual work of requesting, validating, issuing, deploying, installing, and renewing SSL certificates.
  • Automatic renewals. No need to track expiration dates or worry about website downtime. Your certificate is automatically renewed and reinstalled on your server before it expires.
  • Ready for shorter certificates. Very soon, all SSL certificates will be 47-day certificates—CaaS automatically updates your certificates as often as necessary, so you don’t have to worry about expirations or renewals.
  • Simpler billing. You pay per domain, not per certificate; issue as many certificates as you need without paying more.

The best part? It’s fast and easy to set up with pre-built ACME agents that support most server types.

How it Works

Once your server is configured with an ACME-compatible client, CaaS will:

  • Automatically prove domain ownership (via HTTP-01 or DNS-01 challenges)
  • Automatically request & install certificates as needed
  • Automatically renew & replace certificates before expiration — no further manual work required after setup

This direct, server-to-CA communication ensures continuous encryption, eliminates renewal gaps, and reduces operational risk — without relying on calendar reminders or human intervention.
