Buying a multi-domain SSL certificate means getting SSL protection at a great price. They are the best choice for use with Exchange servers, as a single certificate can secure multiple top-level domains. There is no need to set up individual SSL certificates multiple times, and they are often significantly more cost-effective compared to purchasing several separate certificates. This applies to Microsoft Exchange, IIS, Zarafa, Open-Xchange, as well as CRM systems with local domains such as SugarCRM. At SSLplus, you have a wide selection of multi-domain SSL certificates — from domain-validated to organization-validated (organization check), and even extended validation — from trusted brands like Sectigo, Digicert, T-Systems, and Globalsign.
