The Cross-Domain Solutions market is understood as a distinct area of cybersecurity industry dealing with information exchange between computer networks with different security classification levels, trust levels, operational sensitivity levels. It includes the implementation of rigid policies regulating the transmission of information between the domains. The solutions can be implemented both via hardware means (data diodes, secure gateways), as well as through software solutions performing functions of content inspection, sanitization, protocol enforcement, and access control.

Cross-domain systems work by implementing security policies that define what information can flow, its direction, and conditions, thus avoiding any risks related to illegal access, information theft, cross-contamination among networks. Cross-domain solutions implement several security functionalities including encryption, malware scanning, data integrity checks, format conversions, logging techniques necessary for audits, regulatory compliance requirements. Companies compete on factors like bandwidth, latency performance, compatibility with current IT environment, flexibility for responding to new threats.

There is an extensive variety of products on offer, including secure web gateways handling internet traffic, remote browser isolation platforms that isolate users from possible threats, data loss prevention tools that block any unauthorized information transfer, next generation firewalls offering superior threat defense capabilities, insider threat detectors monitoring user activities within secure domains. The customer base encompasses military forces, intelligence services, government ministries, critical infrastructures, commercial firms that need solid data protection solutions in their network structures.
