Rocket.Chat

Rocket.Chat is an enterprise-grade, open-source communication platform designed for organizations prioritizing data sovereignty, security, and advanced collaboration. Running on self-hosted servers or secure private clouds (deployed via Docker, Kubernetes, etc.), Rocket.Chat allows real-time and asynchronous messaging, voice calls, and external federation. The Android client (chat.rocket.android) enables users to connect to their custom organization servers. The system features robust single sign-on (SSO) integrations like LDAP, SAML, and OAuth, protecting access to classified channels in highly regulated sectors.

The application supports various engagement models, including direct messaging, private group rooms, and public discussion channels. To address compliance and security needs in sectors like the public sector and defense, Rocket.Chat supports fully self-managed server deployments. The platform can be deployed in fully air-gapped environments without external internet access, ensuring complete internal control over corporate communications.

From a security standpoint, the application supports single sign-on (SSO) integrations, including Active Directory, LDAP, SAML, and OpenID Connect. These secure directory connections allow corporate IT administrators to easily map user roles and synchronize security permissions across platforms. For mobile security, Rocket.Chat provides ID-only push notifications, which conceal sensitive message content on the device’s lock screen to protect data privacy.

To maintain code security, the Apps-Engine isolates each integration using Node.js virtual machine (VM) modules. This sandboxing prevents custom extensions from accessing the platform's core system or causing data leaks between applications.
