How does SAFEmail® Medium Grade Messaging work?

For Defence and Intelligence organisations that need more than standard Microsoft Outlook message functionality but still want to make use of a Commercial-Off-The-Shelf (COTS) product, SAFEmail® offers a way for users to classify your messages and protect them across a variety of messaging environments. SAFEmail® enables you to organise and control a wide range of data from unclassified to highly-classified quickly and easily, and allows you to add elements of service such as checking the recipient’s clearance level before sending.


  • Seamless integration with Microsoft Office

    Users can easily and intuitively classify documents within Microsoft Office making classification a simple process that quickly becomes second natures.

  • Unparalleled flexibility whatever your security grade

    SAFEmail® modules enable you to build the data protection system you need across a range of low to high security classification desktop PCs.

  • A familiar interface for user training and transition

    Familiar user interface means users can easily use SAFEmail® within Outlook and Microsoft Exchange quickly and consistently with minimal training.

  • Cost effective compliance with the benefits of a COTS solution

    SAFEmail® gives you complete confidence that your email systems are fully compliant with STANAG 4406 and other standards, whilst ensuring your investment in technology is cost effective.

  • Enhanced security with controlled document access

    Ensure that only those with the relevant clearance levels are able to access appropriate emails.
