• Platform

    GuardStack Platform provides a secure, interoperable and self-controlled digital end to end service infrastructure for highly mobile and dynamic critical communication services.

secure middleware for critical communication

GuardStack Platform provides a single "all-in-one" software package for seamless and secure interworking between various protocols, waveforms, access technologies and transmission media in dynamic and highly mobile environments.


The GuardStack Platform integrates various transmission and radio access technologies and provides a vendor and technology agnostic secure middleware in the lowest available Size, Weight and Power (SWaP).


The GuardStack Platform dynamically adapts the ever-changing network topology according to the mission situation and without manual intervention. Services are automatically adjusted according to availability and bandwidth capacity.


Applications and data can be assigned to one of multiple information security domains in which the user participates. He can easily switch between them without changing the device. That eliminates the necessity to persist data in different places and all the intricacies that would come with it.


Communication networks are typically build based on static architectures and topologies within a specific geographical area. Commercial mobile networks refer to end-user mobility.

GuardStack has been designed to mobilize the network itself, delivering service continuity with a network that always follows the mission.
