Mattermost operates a sovereign collaboration and AI automation platform designed for organisations where data control and operational security are paramount. The platform runs on-premises and in private clouds, serving governments, enterprises, and allied militaries globally. It provides secure messaging, file sharing, workflow automation, audio and screen-sharing capabilities, and project management tools accessible via web, desktop, and mobile clients.
The platform emphasises advanced information controls, including attribute-based access control, data classification banners, and data spillage mitigation. It integrates with Microsoft Teams, Outlook, and Microsoft 365, allowing organisations to embed Mattermost into existing enterprise environments. These capabilities enable zero-trust collaboration across operational contexts, from tactical edge and disconnected/degraded environments to enterprise headquarters.
Mattermost supports mission-critical workflows spanning mission planning, real-time operations, DevSecOps, incident response, and cyber security. The deployment flexibility and security architecture reflect its focus on national security and critical infrastructure sectors, where sovereignty over data and complete operational control are essential requirements.
