Rocket.Chat

Rocket.Chat is a secure, open‑source communications platform designed for mission‑critical operations. It combines real‑time messaging, voice and video conferencing, and app integrations in a single environment, with enterprise‑grade security, data sovereignty, and flexible deployment options including on‑prem, air‑gapped, and sovereign EU clouds. Built on a zero‑trust security model with end‑to‑end encryption and comprehensive governance, it supports defense, government, and critical infrastructure use cases while remaining customizable and extensible.
