Military Message Handling Systems (MMHS) have become established as the defacto way of exchanging high grade electronic messages within a national military enclave, between military domains and within operational domains. With well defined, standards based interfaces, Commercial-Off-the-Shelf (COTS) software can meet the needs of most MMHS implementations with only modifications to the systems needed to enable specific functionality. As a result, Nexor have designed and developed a virtual MMHS solution based around products already developed and deployed in MMHS around the world.
