FAQ

FAQ

Do you install SSL certificates for us?

Yes, we install SSL certificates free of charge for YourIT Server Hosting customers. For servers with other providers, we also offer a paid installation service.

What is the difference between wildcard SSL and multi-domain SSL?

A wildcard SSL certificate protects all subdomains of a single domain (*.example.com). A multi-domain SSL certificate protects several different domains (example.com, example.net) with a single certificate.

How do I renew an SSL certificate?

Renewal is available starting 30 days before expiration. YourIT sends an expiration notice email, and free installation is also supported for renewals. An automatic renewal service is also available.

What is the difference between free SSL (Let's Encrypt) and paid SSL?

Free SSL offers the same level of encryption, but has no warranty and must be renewed every 90 days. Paid SSL offers additional benefits such as a warranty, a site seal, organization validation (OV/EV), and a validity period of 1–2 years.

Are any documents required to issue an SSL certificate?

DV certificates are issued with domain ownership validation only, with no documents required. OV/EV certificates require documents verifying the organization's identity, such as a business registration certificate and the representative's ID.
