ARMA Instruments AG

Neutrality in secure communication


ARMA Instruments AG, an acronym to Advanced Relay Mission Applications was founded early 2017 in Baar, Switzerland. We operate a transparency center that invites all our customers to come and investigate our source code. We are open to third party auditing. ARMA Instruments mission is to protect our users to the best of ability technology has to offer and to relentlessly monitor and improve on those technologies.

ARMA G1 Secure Communicator

G1 Secure Communicator

A mobile personal communicator based on the ARMA Linux operating system, using the cellular network. Build on a zero trust approach from hard- en software to manufacturing within our secure facility. ARMA G1 features an absolute minimalistic hardware design to exclude any type of attack and facilitates communication by text only. Can be made operable for communication inside bunkers, onboard ships and airplanes, it has our patented Dynamic Identity, does not rely on a dedicated server infrastructure and matches national TOP SECRET classifications.

Product Features

Dynamic Identity

Dynamic Identity is a mayor improvement in the field of secure communications. Where currently users are easily trackable and identifiable, our ARMA G1 communicator continuously changes its identity, both on the device as well as on the mobile network level. We are the first company introducing this technology and Dynamic Identity is filed for patent under US patent number 16/433,768.

Serverless Infrastructure

Serverless Infrastructure is the first commercially available solution using onion routing for mobile communication that anonymises the user’s routing, metadata, identity, location and makes storing user communication data technically impossible, for anyone. It provides an immensely resilient infrastructure against any form of attack. Bringing our communications down would in effect be bringing down the internet that was built to survive nuclear war.

Controlled ecosystem

ARMA is both developer and manufacturer of its products, excluding supply chain attacks.

Non-extractable keys

Isolated cellular modem

Modem is isolated from the device’s main computing core and has no direct memory access.

Controlled execution environment

Trusted boot and firmware updates and cryptographic verification of the boot image integrity.

Microservice architecture

Individual software components are isolated using operating system containers and are run on a "need to know basis".

Multiple identities are possible on a single device being totally independent.

Zero inbox

We promote a zero inbox principle to be able to conveniently use the device. By default all communicated information is set to expire soon and typically there is no message archive on the device.

Self destruct

All critical hardware components are protected in a tamper resistant enclosure. If the integrity of the device is compromised, all encryption keys are irrecoverably erased.

TEMPEST resistant

Both passive and active measures are in place to ensure the blocking of electromagnetic emissions that otherwise would leak sensitive information.

Unlimited global roaming

ARMA Instruments specifically has no insight into the ARMA G1's geographical location nor the amount of data that it uses. Therefor billing per device is not possible. Subscriptions are based on a 1 year flat fee allowing for a full year of worldwide unlimited and unrestricted use of our service.

Threat Intelligence Center

As part of our Secure Operations Center the ARMA Threat Intelligence Center is based on the collection of intelligence using open source intelligence, social media intelligence, human Intelligence, technical intelligence or intelligence from the deep and dark web. It's key mission is to research and analyse trends and technical developments in the areas of cybercrime,hacktivism and cyber espionage.This enables us to anticipate, respond to and remediate threats on all levels, whether user operational, legislative, distribution or otherwise.

Transparency Center

Our transparency center is open to all our customers. It provides on premises tour of our facilities and has staff available to enable customers to investigate our source code, updates,operations- and threat intelligence center.

Customer & after sales support

Our customer service center is available 24/7 by phone and email through our contact center.We have advanced support standby and an R&D department which handles confirmed bugs or feature requests from customers. Depending on the customers service contract, device guarantee issues are processed under 48 hours from notification.
