Mattermost
Zero Trust collaboration, workflow automation, and sovereign AI — in one platform.

Mattermost is a secure collaboration platform built for national security, cybersecurity, and critical infrastructure teams. It combines encrypted messaging, workflow automation, AI-powered tools, and project management in a single sovereign deployment. The platform emphasizes operational control with features like attribute-based access, classification banners, and no reliance on external third-party services.
Mattermost provides an on-premises or sovereign-cloud platform combining encrypted channels, playbook automation, AI agents, and integrations via open APIs and plugins within a closed perimeter.
