A secure internal Local Area Network (LAN) messenger is a communication tool designed to operate exclusively within an organization’s private network. Unlike cloud-based applications like Slack or Microsoft Teams, a LAN messenger passes data directly between local devices (Peer-to-Peer) or through an on-premises local server. This architectural approach ensures that confidential corporate data never leaves the physical or virtual boundaries of your building, keeping information isolated from external internet threats.
