Air Gapped Communication: How It Works, Benefits, Architecture, and Solutions

Air gapped communication is a method of exchanging messages, voice, video, files, and operational information inside an isolated network environment that is disconnected from the public internet and other untrusted networks. This approach is utilized by organizations that require communication continuity without external connectivity or wish to keep sensitive, classified, regulated, or mission-critical information within a controlled security boundary.

Air gapped communication systems typically involve on-premises servers, private infrastructure, isolated Kubernetes, or dedicated appliances. The primary benefits of air gapped communication include reduced external exposure, keeping communication data within a controlled security boundary, and maintaining infrastructure, data, and access under organizational control.

However, there are limitations to consider, such as the need for updates, dependencies, identity services, backups, and administration to also function within the isolated environment.
