Cross-Domain Communication Solutions

Understanding the Cross-Domain Challenge

Modern military operations require rapid information sharing—intelligence from Top Secret systems must reach operational commanders, while situation reports from tactical units must be elevated to strategic planners. Yet security mandates strict separation between classification levels. Physically separate networks prevent accidental disclosure but create operational friction. Cross-Domain Solutions resolve this tension by providing secure, controlled pathways for information to move between networks while maintaining security. Every byte transferred is inspected, logged, and approved according to security policies.

Types of Cross-Domain Solutions

We implement three primary CDS architectures based on operational requirements. Data Diodes allow one-way information transfer from high-to-low classification, ideal for intelligence dissemination. Guards perform content inspection and filtering, enabling controlled bidirectional transfer for email and files. Gateways provide full service interoperability, supporting applications like VoIP and web browsing across domain boundaries. All solutions undergo NSA evaluation and certification, with configurations tailored to your specific security policy and operational workflow.

Content Inspection & Policy Enforcement

The core function of CDS is policy enforcement. Our guards implement deep content inspection, examining every file, email, and data packet for policy violations. Machine learning algorithms detect anomalies indicating data spills or insider threats. Human-in-the-loop review processes require manual approval for transfers exceeding automated confidence thresholds. All transfers are logged with full audit trails, supporting security investigations and compliance reporting. The system integrates with PKI infrastructure, ensuring only authorized users can initiate transfers.

Operational Use Cases

Intelligence fusion centers use CDS to sanitize classified intelligence reports for release to coalition partners at lower classification levels. Cybersecurity operations centers employ guards to correlate unclassified threat intelligence with classified network activity. Video teleconference gateways enable participants on SECRET and TS/SCI networks to join the same briefing. Email guards allow coordination between classified planners and unclassified logistics personnel. In every case, CDS enables mission-essential collaboration while maintaining security.
