Microsoft 365 Mail Security

NoSpamProxy – secure email communication in M365

Many companies are currently introducing Microsoft 365 as a cloud solution and part of their digital transformation. However, the shift to cloud-based and flexible working enabled by the modern workplace must not come at the expense of security or data protection. Emails are still the biggest gateway for cyber attacks. Many experts therefore recommend using additional mail security solutions such as NoSpamProxy, as Exchange Online Protection (EOP) and Microsoft Defender for Office 365 do not offer optimal protection and also have some disadvantages in the area of encrypted communication.

NoSpamProxy – the ideal complement to Microsoft Defender for Office 365

Especially in the face of increasingly complex cyber attacks, the security measures offered by Microsoft are often no longer sufficient. NoSpamProxy offers protection against spam and malware as well as secure email encryption for your M365 emails. Guaranteed security, transparency and simplicity in a mail gateway Made in Germany.

Microsoft 365 already offers classic security functions such as spam and virus protection, but these can only be adapted slightly. In contrast to NoSpamProxy, an extensive, differentiated configuration is not possible. In addition, central management – for example, of certificates for encryption – is not available. This means a considerable additional effort for IT administrators compared to NoSpamProxy.

NoSpamProxy is the ideal complement for your email security and spam protection – for optimal protection in the M365 cloud. In addition, in the area of domain security, a coordinated combination of SPF, DKIM, DMARC and DANE ensures outstanding protection against phishing attacks and spam.

Make a smart addition to Microsoft 365 Mail Security: Email encryption as a cloud service

Microsoft 365 is an excellent basis for digital transformation. Unfortunately, however, M365 does not offer a practical and thus compliant solution for confidential email communication for at least three reasons. The solution lies in supplementing M365 – for example with the cloud service from NoSpamProxy. The gateway-based solution can be fully integrated into M365 and, with automated certificate management, is ready for use within a few hours. Further plus points: The solution stands for security made in Germany and offers award-winning support.

M365 does not provide a practical and compliant solution for confidential email communication:

  • Microsoft’s own encryption mechanism is proprietary and requires registration with the sending tenant.
  • Client-based encryption fails in practice because the correct keys are often not available when using several end devices.
  • The lack of automatic management of certificates leads to enormous administrative efforts.

„We know many products from our research activities. NoSpamProxy convinced us with its performance and usability like no other product. I can recommend NoSpamProxy as a supplement for mail security to all companies that are switching to M365.“

Oleg Ludwig, IT Manager at techconsult
