Mattermost is a secure, self-hosted collaboration platform designed for mission-critical environments that require complete data control. While primarily built for enterprise teams in defense, government, and critical infrastructure, community builders in regulated industries or security-conscious organizations use it to create sovereign chat-based communities. The platform offers messaging, file sharing, workflow automation, and integrations while ensuring all data remains on-premises or in private clouds, making it ideal for professional associations, developer communities, and enterprise customer communities that need strict security controls.
