ViaSat High Assurance Filters are Cross Domain Solution (CDS) products that act as stand-alone, high assurance devices. These trusted filters solve air gap challenges encountered by defense and government organizations by securely permitting data to pass between different security classification levels or domains of a network. The filters are based on the ViaSat PSIAM™ Cryptosystem architecture to deliver rule enforcement in a secure, tamper-protected environment.

These trusted filters insure that only the desired data is permitted to cross classification boundaries. When positioned in an application network, the High Assurance Filters ensure that no traffic crosses from one security domain to another without filter review. Each trusted filter, including the HAF-100, HAF-100A, and HAF-200, can filter one-way and two-way message traffic.
