Lower Your Total Cost of Ownership

Systems exposed to classified information in the field must be physically guarded or properly sanitized. Our built-in board volatility features ensure no classified data is unintentionally stored on the hardware, avoiding the need for expensive handling.

Secure Your Server Cluster

When configured as a boot server, RES Trust ensures only authorized personnel can modify the cluster. Built-in cryptography and physical security delivers assurance and maintains data integrity even when the stack is offline or remotely accessed, making it ideal for edge applications.
