 For examples, in the US, an evaluation at the EAL 5 or EAL 5+ (EAL 5 Augmented) or higher is required to export from a Secret domain to an Unclassified domain.Some manufacturers may use "Trusted Computer System" or "Trusted Applications with High Assurance" as an equivalent term to HAG.The HAG is mostly used in email and DMS environments as certain organizations may only have unclassified network access, and they need to send a message to an organization that has only secret network access.
