Secure communications in air-gapped networks.

Resilient messaging for classified and isolated environments.

air-gapped

For the most secure and restricted networks.

Mission-critical operations demand a communications backbone independent of the public internet. The gold standard for security, air-gapped networks provide physical separation from other networks to protect classified information.

Element delivers a sovereign communications solution designed for total isolation. It provides absolute control over infrastructure, software and data where external connectivity is either prohibited for security or simply unavailable.

Air-gapped with that extra element.

Element provides a deployment-ready air-gapped solution that supports digital sovereignty, interoperability and end-to-end encryption. It can be configured to support a range of use cases.

Strategic command and headquarters

Critical operations require a standalone, self-contained communications environment. Element provides a secure backbone ensuring that sensitive data remains entirely within the protected perimeter without any external dependencies.

Federated global operations

Mission success often depends on coordination across multiple physical locations. Element facilitates secure federation between disparate air-gapped sites, allowing teams to communicate privately across a distributed network while remaining entirely disconnected from the public internet.

Integrated mission domains

National security often requires sharing data across different classification levels. Element’s Cross Domain Gateways act as a secure passage to bridge partitioned networks, enforcing policy-driven transfers and enabling controlled, secure information flow between disparate domains.

The tactical edge

Field units, submarines and vehicles operate in demanding environments. Cross Domain Gateways provide a secure passage to connect submarines to the landside. Optimised for high-latency and intermittent links, Element ensures remote units stay synchronised with the private core.

Resilient tactical hardware

Modern missions require flexibility at the edge. Element is compatible with ruggedized hardware, mesh radios and private satellite links where Cross Domain Gateways can bridge partitioned networks to enable secure information flow where network domains are strictly separated.

The importance of a modern air-gapped solution.

Security without usability creates operational risk. Air-gapped environments impose strict constraints, but classified operations demand efficient, resilient communication.

Sovereignty

Protecting sensitive data requires a communications backbone with zero external dependencies. The solution must operate in total isolation during both deployment and operation to remove any associated risks.

Predictable accreditation

Security assessors require stable, predictable software to minimise the burden of compliance. A vendor-backed system with LTS and technical support provides a clear maintenance cadence, ensuring frequent technical changes do not trigger constant, costly re-accreditation cycles.

Breaking information silos

Strict network separation often forces a reliance on slow manual processes. Policy-enforced cross domain flows replace manual coordination with near-instantaneous information sharing, turning isolated data into actionable intelligence.

Tactical edge resilience

Military and field operations often occur in Disconnected, Intermittent, and Low-bandwidth (DDIL) conditions. Communication must remain reliable despite high packet loss or latency, ensuring connectivity where conventional messaging fails.

Secure communication across classification levels.

Connect

Element’s Cross Domain Gateways facilitate secure, seamless communication between high-side and low-side networks. Residing within a highly-trusted environment, the hardware decrypts, inspects and re-encrypts data to enforce strict data-loss-protection rules during every domain transition.

By replacing slow manual coordination with policy-driven flows, the solution ensures that network separation never hinders rapid decision-making. This enables near-instantaneous information sharing across disparate security levels while maintaining absolute domain integrity.

Modern usability

Element offers productivity with an intuitive, consumer-grade messaging interface with features including embedded voice and video, read receipts, threads, emojis and message editing to improve operational speed while remaining entirely isolated.

Monitor multiple rooms and live data feeds within the air-gap environment from trusted systems simultaneously. Essential for mission-critical control rooms, contact centers and cyber operations.

Element messenger

Mobile-first design

Many air-gapped environments only support desktop communications, Element can support handheld devices for use within an air-gap with a consumer-style messenger app.

Hardware authentication

Hardware authentication

Native support for X.509 client certificates and hardware-based tokens ensures that even the most modern interface meets the strictest identity and encryption standards.
