Nexor has a rich history of deploying Military Messaging Handling System (MMHS) solutions that support mission-critical systems. For over 25 years our military messaging solutions have been delivered to defence organisations around the globe

Why do MMHS solutions exist?

In today’s military operations there is an increasing reliance on both coalition partners and network-enabled capability. This combination means that there is an ever-growing requirement for the secure exchange of information between different nations’ forces.

These organisations operate in a wide range of messaging environments and it is vitally important that these disparate systems can communicate with one another in a secure and timely way in order to ensure that critically sensitive information can be received on time and that it is not compromised in the process.

However, the differing messaging standards mean that a message from one environment cannot always be properly understood by another environment. In theatre, the ability to exchange information accurately and quickly is vitally important, not only to the operation’s efficiency but with regard to the safety of the personnel involved.

Examples of the challenge are mapping SMTP messages into an X.400 format or converting a FLOT label to a STANAG 4406 compliant security label.

A Reference Architecture for MMHS solutions

To meet these challenges, we developed our Military Messaging Handling System (MMHS) reference architecture to show all of the components needed.

Further information can be found in our MMHS: A Reference Architecture White Paper and the complementary MMHS: The Requirements White Paper.

Why is Nexor trusted to supply MMHS solutions around the world?

Since we developed our MMHS Reference Architecture this approach has been widely adopted throughout the sector. Our innovative MMHS solutions have created competitive advantage for our customers and on several occasions we have created a solution that proves to be a technological first.

Underlying our creativity is a value set that encompasses our commitment to customer service, communication and continuous improvement. We believe in ‘doing things properly’ and that’s why our customers have such high levels of confidence in our MMHS solutions.

We have developed long-term relationships with key system integrators and military organisations, such as NATO and the European Defence Agency.

To enable you to implement every element of the MMHS architecture we have developed a suite of technology components. This includes:

Supporting other protocols

To support protocols other than messaging, we have also developed and implemented the Information Exchange Gateway reference architecture.
