Cross Domain Solutions Plug-in

The internet is the classic example of how information crosses multiple domains into and out of private networks. However, trust boundaries are practically everywhere. When a file crosses a boundary, you need to know a threat doesn’t have room to hide.

The Glasswall Cross Domain Solutions Plug-in provides a vital air-gap for files moving between trust boundaries, whether they’re inside your organization or across a public network.

How it works

The Glasswall Cross Domain Solutions Plug-in mediates the flow of files from a source location (e.g. Dropbox) onto the Glasswall CDR Platform which instantly cleans and rebuilds files to match their known good manufacturer’s specification – then places the safe file to a destination location which is typically in a higher trust zone.

CDR implementations can be chained together, as they span different domains to ensure that the process is double-blind. Files are processed in dedicated Kubernetes Pods and Containers which are destroyed once a sanitized file is emitted, ensuring the integrity of the environment.

Raising the bar on file security

We believe people should be free to open their files without fear. To click on anything without risk of catastrophe. To use systems the way they were meant to be used. That’s why we’re raising the bar on file security at Glasswall.
