Probity’s Fastback Optical Data Diode allows organizations to implement a next-generation solution quickly, efficiently, and securely—right out of the box.


The Fastback Kit is a complete, lightweight solution that uses commodity hardware to move data at speeds up to 8Gbp/s in a uni-directional flow.

Fastback has been evaluated by the National Security Agency (NSA) and was recently added to the NCDSMO’s Official Data Diode List.

Fastback uses commodity hardware and drivers to allow fast, reliable setup using existing hardware, and can be interfaced with commercial RTB-compliant cross domain guards.

Fastback is an affordable, scalable solution that allows you to leverage commodity servers, guards, and hardware without the expense of replacing your existing components or worrying about proprietary compatibility.

Fastback’s optical hardware kit provides physical Denial of Connectivity into protected networks. Supports UDP, RTP, SCP, NFS, and SFTP protocols. A video streaming option is also available.

Probity’s expert Cross Domain Solutions team is available to help with custom integration, inspection, and workflow orchestration support to create a complete, concise system for any mission requirement.
