Last updated

Table of Contents

DNSimple provides an SSL certificate interface you can use to purchase a new SSL certificate. Buying a Sectigo certificate through DNSimple costs $20 per year for a single-name certificate or $100 per year for a wildcard SSL certificate.

Starting March 15, 2026, Sectigo SSL certificates sold by DNSimple are valid for a maximum of 200 days due to CA/Browser Forum requirements. You will need to purchase a new certificate before it expires to maintain uninterrupted coverage. Seven days before the certificate expires, you will begin receiving renewal notices.

Before You Start

To order an SSL certificate you need a DNSimple account.

Note

You do not need an active subscription to buy or renew a Sectigo certificate. Without one, you pay for the certificate at checkout.

You can order an SSL certificate for a domain, even if the domain is hosted elsewhere or registered with another registrar. You are not required to transfer or host a domain with us to purchase a Sectigo SSL certificate.

Please ensure you comply with all the technical requirements in our Getting Started with SSL Certificates page before ordering the certificate.

For more details about the configuration, approval, and installation of the certificate, read the Getting Started with SSL Certificates article, or follow the instructions on the site after you purchase the SSL certificate order.
