Ensure complete Email security in the cloud or in a hybrid scenario with NoSpamProxy.

Complete cloud-based email security

NoSpamProxy in a private cloud, in Azure or as a managed service

Many organisations are faced with the question of whether they should transfer part of their email infrastructure to the cloud, for example in the course of a Exchange migration. For this and other scenarios, NoSpamProxy provides optimum support; simple, flexible and secure. And did you know that NoSpamProxy also supports hybrid Microsoft Exchange scenarios where one part is operated on-premises while the other part is hosted in Office 365?

All of the powerful NoSpamProxy features for email encryption, spam and malware protection as well as large file transfer are also available as a cloud-based service.

Thanks to its architecture featuring a central gateway role for configuration and control as well as multiple gateway roles for handling and processing of email traffic, NoSpamProxy is able to optimally map all possible scenarios.

Constant communication between the various roles ensures that the gateway is always up-to-date on all communication relationships of an organisation and has all public keys available at any time. Installation can be carried by one of our managed service provider partners on virtual servers in a private cloud, in Azure, or as a managed service.

First secure email gateway featuring with Office 365 connector

Easily configure NoSpamProxy as a virtual email security gateway for Office 365

Microsoft Office 365 already offers conventional security features for spam and virus defence at the client level, but without the possibility to configure these features to adjust them to the exact needs of your organisation. In addition, centralised management of certificates or cryptographic keys is not supported. This results in significantly higher expenses compared to proven gateway-based solutions. To avoid the pedestrian task of redirecting emails from the Microsoft cloud via a gateway in the corporate network, the NoSpamProxy Azure Edition is available as a virtual gateway in Microsoft Azure. This way, IT administrators do not have to give up the benefits of a central administration for their company’s email security. In addition, a quarantine is no longer required with NoSpamProxy. By eliminating the need for the regular check of the quarantine for potentially incorrectly blocked emails, dealing with emails is much more efficient compared to the conventional spam filter included in Office 365.

The classic case – the hybrid scenario

NoSpamProxy can easily be used in a hybrid scenario

For many companies it is a common practice to operate Microsoft Exchange in a hybrid scenario, with one part being operated on-premises and the other other in the cloud. This scenario can be precisely reproduced and managed centrally with NoSpamProxy.

When receiving e-mails, NoSpamProxy checks (in addition to the standard filter technologies) whether the sender maintains SPF, DKIM or DMARC records, and includes the result in its evaluation of e-mails.


Via the Office 365 Connector, NoSpamProxy has itself configured in such a manner that Office 365 sends e-mails to NoSpamProxy and delivers these e-mails to Office 365 after application of the security function.


Secure transmission of e-mails to the client with TLS encryption.


All e-mail clients securely receive their e-mails.
