The Vault is a small form factor PC built for use as a firewall / router.  The FW4A is based on a 4 network port design that leverages a low power, but versatile Intel Atom E3845 CPU.  This CPU supports AES-NI, Intel’s Hardware Acceleration for Encryption.  The Vault uses standard Intel components (including Intel network ports) which results in compatibility with a variety of operating systems, including a number of open source firewall projects.  The Vault is fanless so it has no moving parts, which results in an incredibly durable platform that can be used in less than ideal environments.  Its all aluminum enclosure (no plastic here) is a giant heat sink, keeping the CPU cool.  The enclosure also comes with pre-drilled holes for an available wireless kit (available here).

The FW4A can accommodate up to 8GB of DDR3L RAM and 1TB mSATA storage drive.
