European ACME SSL certificate providers

An SSL certificate proves who runs a website and lets browsers open an encrypted HTTPS connection to it. Certificates are issued by certificate authorities, and the providers listed here all support ACME, the protocol that automates domain validation and renewal. Because the whole exchange is scripted, certificates can have short lifetimes and your server can replace them without anyone touching a control panel.

Certificate authorities sit at the root of the trust your visitors place in your site, so it is worth knowing who signs your keys and under which legal system they operate. Actalis SSL is one European option in this list. Picking a European alternative to a US certificate authority keeps the issuing organisation, its support desk and its billing under EU and EEA rules, and ACME means switching later stays cheap.
