SSL for Microsoft Internet Information Services (IIS)

Buying a multi-domain SSL certificate means saving money on SSL protection. These certificates are the best choice when used with Exchange servers, as they can secure multiple top-level domains with just one certificate. There's no need to install multiple individual SSL certificates, and they are often significantly more cost-effective compared to purchasing separate ones. This applies not only to Microsoft Exchange and IIS, but also to platforms like Zarafa, Open-Xchange, and CRM systems with local domains such as SugarCRM. At SSLplus, you’ll find a wide range of multi-domain SSL certificates — from domain validation and organization validation (business check) to extended validation — from trusted brands like Sectigo, Digicert, T-Systems, and Globalsign.
