Cloud tools cannot cross the air gap.
Control rooms and protected zones are cut off from the internet by design, so cloud messaging simply does not reach them.
Secure communication for the grid, the plant and the field.
Troop Messenger gives grid operators, power generators, oil and gas companies and water utilities a secure messaging platform that runs on their own servers or on a fully isolated network. Control rooms, engineers, field crews and contractors communicate with end-to-end encryption, a complete record, and no dependence on a public cloud.
- Air-Gapped
- On-Premise
- Enterprise-Grade Security
What Is Secure Communication for Energy and Utilities?
Secure communication for energy and utilities is messaging, calling and alerting that runs inside the operator’s own protected network, so control room, engineering, field and contractor conversations never pass through a public cloud.
Many operators keep a mainstream collaboration tool for the business network and add a separate, isolated messenger for control rooms and sensitive sites. Troop Messenger is built for that isolated side: on-premise or fully air-gapped, end-to-end encrypted and fully auditable.

Why Critical Sites Need an Isolated Messenger
Attackers target the people, not only the systems.
Chat on public platforms exposes outage plans, site details and credentials to the wider internet.
Regulators expect a record.
Grid and critical infrastructure rules ask operators to show who was told what, and when, during an incident.
Outages need everyone at once.
Storms, faults and emergencies need control rooms, engineers, field crews and contractors on one channel, fast.
Case study
Case Study:Transgrid (Australia)
An electricity transmission operator keeping its most sensitive conversations off the internet.
The challenge
A secure space the business network could not provide
Transgrid uses a mainstream collaboration tool across its facilities, but its main office needed messaging inside an environment with no connection to the internet.
The deployment
Air-gapped environment with end-to-end encryption
Troop Messenger operates within Transgrid’s air-gapped environment at its main office, with the end-to-end encryption module enabled.
The outcome
Renewed on a multi-year licence
Transgrid has continued its partnership with Troop Messenger through a multi-year licence renewal.
