Nexor Edge

Assured data guard capability for space-constrained and tactical environments

Nexor Edge combines data guard, proxy, and data diode functions in a single, compact 1U unit, delivering certified, one-way, policy-controlled data transfer wherever size, weight, and power are limited.

As digital operations move closer to the tactical edge, many environments cannot accommodate traditional 3U data centre deployments. Nexor Edge provides the same trusted assurance as the flagship diode technologies but in a smaller, lighter, and more power-efficient form factor.

Designed for Defence, Government, and Critical National Infrastructure, Nexor Edge enforces one-way information flow, performs deep content inspection and sanitisation, and applies policy control, all within a single, deployable unit engineered for edge or mobile use.

What is an Edge Guard?

Nexor Edge is a certified, integrated data guard and data diode solution optimised for space-limited or power-restricted environments.

It consolidates three elements, two secure proxy servers and a high-assurance data diode, into a single 1U chassis, reducing physical footprint by over 80 per cent while maintaining full assurance and performance.

Nexor Edge delivers:

Unidirectional data flow is enforced by a hardware diode
Content inspection and sanitisation (CDR)
Policy-controlled information exchange
Cross-domain compatibility for classified and operational systems

Its smaller footprint makes it ideal for deployed headquarters, mobile command posts, remote facilities, or environments where power and space are at a premium.

The Nexor Edge family

The Nexor Edge family delivers high-assurance cross-domain security at the tactical edge, enabling controlled information flow in demanding environments. Each variant applies the same trusted security principles while addressing different constraints around size, performance, and operational flexibility.

Nexor Diode Edge

Compact, low-power diode delivering assured one-way data transfer for space- and power-constrained deployments.

Nexor GuarDiode Edge

Portable edge guard combining one-way transfer with content filtering and policy enforcement for tactical operations.

Nexor GuarDiode Edge+

High-performance portable edge guard with increased throughput, broader protocols, and virtualised capabilities for advanced missions.

Together, the Nexor Edge solutions provide a scalable path from compact one-way transfer to advanced, policy-driven edge security. This allows organisations to deploy the right level of assurance and capability wherever missions require secure, reliable data exchange.

Enhanced edge capability

For customers requiring additional flexibility, Nexor Edge+ extends the platform to host supplementary, approved applications alongside the Nexor guard.

This enables the integration of operational tools such as Elasticsearch, Kafka, Splunk, or other mission-specific applications, allowing local data processing, monitoring, and analytics directly on the same hardware, all within the same assured boundary.

Nexor Edge+ provides:

Integrated multi-application support;
Flexible compute and storage allocation;
Certified one-way data transfer with policy enforcement;
Deployment efficiency with reduced hardware count.

This makes Edge+ ideal for field-deployable networks, temporary operations, or CNI sites requiring both secure data transfer and in-situ processing.

Benefits of using an Edge Guard

Choosing Nexor Edge offers several distinct advantages for organisations requiring secure, space-conscious data transfer solutions. Here’s why Edge Guards are the smart choice:

Reduced footprint

Frees up valuable rack space and enables deployment in constrained facilities or mobile units.

Rapid deployment

Single-box design simplifies installation and configuration, reducing setup time.

Lower power consumption

Suitable for generator-powered or remote installations where energy efficiency matters.

Mission agility

Compact form factor enables secure information exchange wherever operational needs arise.

Consistent assurance

Maintains the same high-grade security, content inspection, and certification pedigree as the full GuarDiode.

Operational versatility (Edge+)

Allows integrated applications for monitoring, analysis, or data visualisation at the edge.

Nexor GuarDiode Edge delivers the full strength of Nexor’s assured data-guard technology in a compact, deployable form, enabling secure, policy-controlled information exchange wherever size, weight, or power impose constraints.

Key Features of Nexor Edge

Nexor’s Edge Guards are packed with innovative features designed to deliver top-tier data security while optimising space. They are the perfect solution for industries such as defence, government, and secure communications, where both security and efficiency are paramount:

Compact 1U design

Occupies one-sixth the space of a standard GuarDiode, enabling secure deployments in tight locations.

Low size, weight, and power (SWaP)

Engineered for mobile or energy-limited environments without compromising assurance.

Integrated data guard and data diode architecture

Combines proxy, inspection, and one-way transfer in a single chassis.

Deep content inspection and sanitisation (CDR)

Detects and removes malicious or non-compliant content before release.

Policy enforcement and audit logging

Ensures every data flow complies with defined security rules and is fully traceable.

Cross domain capability

Supports secure data exchange between networks of differing classifications.

Edge+ multi-application hosting

Runs approved operational software (e.g., Elasticsearch, Kafka, Splunk, Metasploit) alongside the guard for local processing and analytics.

High-assurance diode certification

Built on the same certified unidirectional technology used in Nexor’s accredited diode technologies.

Typical applications

Tactical and deployed headquarters

Delivers assured data-exchange capability to mobile command or forward-operating environments, where traditional 3U systems are impractical.

Remote or temporary facilities

Ideal for operations centres, research labs, or temporary security zones that require accredited data-guard functionality in minimal space.

Critical infrastructure control rooms

Protects sensitive process-control or monitoring networks while fitting into existing racks or control enclosures.

Maritime, air, and transport systems

Provides certified one-way data transfer between onboard networks and ground infrastructure within strict size, weight and power (SWaP) limits.

Certified assurance in a compact form factor

Nexor Edge and Edge+ are built on the same trusted architecture and high-assurance principles as the certified Nexor GuarDiode.

Each unit integrates a Common Criteria EAL7+ data diode core within Nexor’s accredited guard framework, maintaining the same assurance pedigree in a smaller, deployable platform.

The Edge range is designed and assembled within Nexor’s controlled UK supply chain, ensuring full provenance, configuration management, and audit traceability.

Every deployment can be documented and accredited under the same frameworks used for Nexor’s 3U systems, giving customers confidence that assurance is never compromised by size.

Full assurance, half the space

Nexor Edge and Edge+ deliver the same certified, policy-controlled information assurance as Nexor’s flagship systems, optimised for environments where every unit of space and watt of power counts.

Bring trusted data guard assurance to the tactical edge

Nexor GuarDiode Edge delivers accredited one-way data transfer, content inspection, and policy control in a compact, energy-efficient form, proven in Defence, Government, and CNI deployments.
