Cross Domain Solutions for Classified and Sensitive Networks
Networks that carry classified or sensitive data must remain isolated by policy, but the missions they support still depend on information crossing those boundaries and users reaching across them. Cross Domain Solutions (CDS) close that gap by enforcing security policy at the boundary, controlling what data crosses, in which direction, and who can reach across, so the separation stays intact while the mission moves forward.
Everfox provides a suite of Cross Domain Solutions that enable organizations to move and access data across network boundaries, enforce one-way flow in hardware, strip threats at the point of transfer, and give operators access to multiple networks from a single workstation.

Cross Domain
Access Products
Everfox Cross Domain access products let operators reach multiple networks from a single workstation. Each addresses a different access scenario: on-site, remote, coalition, or hardware-isolated. Deploy one where it’s needed, or layer them to scale with the mission.

Cross Domain
Transfer Products
Everfox Cross Domain transfer products move data across classification boundaries through content inspection, format validation, or hardware-enforced one-way flow. Each product below is built for a different combination of throughput, data types, and enforcement methods.
Move data across classification boundaries

COMPLEX FILE TRANSFER
Trusted Gateway System (TGS)
Multi-directional guard for file transfer across classification levels. Supports inspection, sanitization, and policy enforcement at scale, with optional Cross Domain email and print capabilities. NCDSMO listed and Raise-the-Bar compliant.

DEFENSE-GRADE BOUNDARY
Data Guard
Policy-enforced content inspection, validation, and transfer for bi-directional or uni-directional boundaries. Common Criteria evaluated defense-grade protection for military applications, coalition partners, and regulated industries.

TRAINING & SIMULATION
SimShield
Purpose built Cross Domain guard for live virtual constructive training environments. Validates fixed format simulation data across TENA, HLA, and DIS protocols and enforces separation between participating forces and exercise networks. NCDSMO listed and Raise-the-Bar compliant.
-
NO RETURN PATH
Data Diode
One-way data flow enforced in hardware. Eliminates the return path at the physical layer for networks where reverse data flow must be impossible, not just policy-prohibited.
-
BI-DIRECTIONAL ENFORCEMENT
High Speed Verifier (HSV / HSV-T)
Hardware-enforced data verification at high throughput. Validates and confirms that only properly formatted, policy-compliant data reaches the destination network.
Threat Protection Products
Everfox threat protection products deconstruct incoming files and rebuild them to known-good specifications, removing threats that signature-based detection cannot catch. Each product below deploys differently: standalone, at the Cross Domain boundary, via API, or as a SaaS integration.
Strip threats before they reach the destination network
-
FILE SANITIZATION
Content Disarm & Reconstruction (CDR)
Incoming files are deconstructed and rebuilt to known-good specifications, delivering only reconstructed content. Effective against zero-day exploits and threats that signature-based detection cannot catch.
-
CROSS DOMAIN CDR
Information eXchange (IX)
Bidirectional CDR at the Cross Domain boundary. Removes threats and enables secure transfer of email, web API traffic, files, and activity logs between separated networks.
-
CLOUD-NATIVE CDR
Application eXtension (AX) APIs
Cloud-native CDR deployable into workflows and applications via API. Integrates Everfox threat protection into existing architectures.
-
EMAIL SANITIZATION
CDR for Mail (Microsoft 365)
CDR delivered as a SaaS integration for Microsoft 365 Mail. Sanitizes inbound email by deconstructing and rebuilding attachments and embedded content before delivery to the inbox. Deploys without on-premises infrastructure.

Use Cases
What Cross Domain Solutions Make Possible
Cross Domain Solutions support missions where data must cross classification or trust boundaries under policy and without compromise. The same architecture that protects defense intelligence cycles also secures critical infrastructure networks, enables coalition data sharing, and builds the pipelines that move training data into sensitive environments.
Regulated and Global Use Cases
-
Critical Infrastructure and OT Security
Operational technology networks stay isolated while sensor telemetry, control system updates, and compliance data cross to enterprise IT with policy enforced at the boundary.
-
Coalition and Partner Data Sharing
Allied nations and partner organizations share finished intelligence with releasability enforced at the boundary. Sources, methods, and sovereign data stay protected on each side.
-
Secure Pipelines for AI and Analytics
Training data and models move into sensitive environments while validated outputs flow back to the systems that consume them. Provenance and classification are preserved throughout.
Defense Use Cases
-
ISR Collection and Dissemination
Finished intelligence reaches decision-makers faster because collection, analysis, and dissemination cross classification boundaries at network speed.
-
Time-Critical Threat Response
Sensor data reaches response systems across classification levels before the engagement window closes. Network-speed transfer where seconds determine the outcome.
-
Multi-Domain Workstation Access
One workstation provides access to multiple classified and high-threat networks. Analysts and operators work across authorized domains without switching devices, reducing hardware footprint and increasing operational tempo.

Cross Domain Solutions FAQ
A Cross Domain Solution (CDS) controls how data is accessed, moved, and protected between networks that policy requires to stay separate. A CDS enforces security policy at the boundary, controlling what data crosses, in which direction, and who can reach across, so the separation stays intact while the mission moves forward.
A Cross Domain guard inspects content, applying filters and policy rules before data crosses the boundary. A data diode enforces one-way data flow in hardware, making reverse communication physically impossible. Guards are right for boundaries that need bidirectional transfer with deep inspection and threat protection. Diodes are right for boundaries where no return path can exist. Everfox builds both and often they are paired together for specific operational environments.
Cross Domain access lets a user reach data and applications on multiple networks from a single endpoint without the data leaving its source network. Cross Domain transfer moves data between networks through content inspection, format validation, or hardware-enforced one-way flow. Most mission programs need both. Everfox provides access solutions alongside transfer guards and data diodes under one portfolio.

Yes. Everfox Cross Domain products deploy in enterprise data centers, cloud environments, and tactical environments. Zero Trust architecture addresses trust within and across networks, but it does not replace the classification boundary. A Cross Domain Solution enforces policy at that boundary, controlling what data crosses, in which direction, and in what form, regardless of the underlying infrastructure.
Everfox, formerly Forcepoint Federal, builds on a 25-year heritage in trusted high-assurance cybersecurity. All product capabilities, NCDSMO listings, and customer relationships carried forward under the Everfox name.
A firewall controls traffic between network segments based on ports, protocols, and IP addresses. A Cross Domain Solution enforces security policy at classification boundaries, controlling what content crosses, in which direction, and in what form. A CDS often inspects and validates the data itself, not just the connection carrying it.
