Secure messaging for ministries of defence.
Troop Messenger gives a ministry of defence one secure channel for messaging, calls and file sharing across departments, service headquarters, defence agencies and industry partners. It runs on the ministry’s own servers or a fully air-gapped network, so every conversation stays under national control.

What Is Secure Messaging for a Ministry of Defence?
Secure messaging for a ministry of defence is a messaging, calling and file-sharing platform that the ministry hosts and controls itself, so policy, procurement and operational discussions between departments, the armed services and industry never pass through a third party’s servers.
It replaces the mix of email, desk phones and personal messaging apps that ministries fall back on, with one system that follows the ministry’s own hierarchy, keeps a complete record and works on classified networks.
| Used by | Ministry departments, service headquarters, defence agencies and approved industry partners |
|---|---|

| Hierarchy | Units and user authorisations that mirror the ministry’s structure |

| Integrations | REST APIs for e-Office, document management, HR and procurement systems |
| In use at | UK Ministry of Defence (UKHO), Ministry of Foreign Affairs Singapore, Indian Air Force |
Why Ministries Outgrow Email and Consumer Apps
Too many channels.
Decisions are split across email, desk phones and personal messaging apps, so nobody has the full picture and nothing is recorded in one place.
Data under someone else’s law.
Messages held by a foreign-headquartered provider can be subject to that country’s legal demands, whatever the contract says.
Industry and allies need access.
Contractors, integrators and partner nations must join specific discussions without receiving an account on the ministry network.
Every decision needs a record.
Parliamentary questions, audits and inquiries need to show who said what, to whom and when.
