NoSpamProxy® - Microsoft 365 Mail Security

NoSpamProxy®: The perfect complement for Microsoft 365.

For secure e-mail communication in M365.

Microsoft 365 with Microsoft Defender for Office 365 and Exchange Online Protection (EOP) already covers traditional security features such as spam and virus protection, but these can’t really be customised and it’s not possible to, for example, manage certificates centrally. NoSpamProxy® provides optimum protection and secure S/MIME 4.0 encryption in the Microsoft 365 cloud.
