Self-Sovereign Collaboration#

As data privacy laws tighten and geopolitical risk escalates, organizations must rethink how they control and protect communications. Cloud-centric collaboration platforms often introduce legal exposure, third-party monitoring, and cross-border compliance conflicts—putting operations and data at risk. Whether driven by internal policy, regulatory mandates, or national data sovereignty requirements, more organizations are moving toward self-sovereign collaboration models.

Mattermost provides a secure, extensible collaboration platform that delivers full control over data, infrastructure, and compliance posture. Built on a self-hosted, open core foundation, Mattermost supports localized deployments across air-gapped, private cloud, and sovereign environments—ensuring organizations can future-proof operations, meet global compliance demands, and maintain continuous operational continuity without third-party dependencies.

Secure, Mission-Focused Collaboration to Enable Faster, Informed Decision-Making across Environments.

The following mission-ready sovereign collaboration capabilities are available:

Localized Compliance and Data Control#

Managing global operations means adhering to regional regulations—without compromising productivity or communication security.

Benefits

Secure, Sovereign Deployment at Any Scale#

From national critical infrastructure to defense-grade networks, Mattermost offers flexible deployment models that preserve sovereignty and continuity.

Benefits

  • Deploy in classified, air-gapped, or disconnected environments using Kubernetes-based deployments and STIG-hardened container images to support classified operations and sensitive data workflows.

  • Eliminate third-party monitoring with full control over infrastructure, encryption keys, access policies, and system-level logging.

  • Scale to meet operational growth with horizontal scalability architecture that supports tens of thousands of users in sovereign environments without degrading performance or control.

  • Maintain operational continuity under cyber or supply chain disruption using fully self-managed infrastructure that ensures collaboration continues even during cloud outages or external service failures.

Interoperable Mission-Partner Collaboration#

Cross-agency, multinational, or coalition collaboration requires sovereignty without isolation—supporting joint operations while preserving organizational boundaries.

Benefits

Unified Collaboration for Secure Workflows#

Legacy collaboration tools—such as Skype for Business and other end-of-life platforms—can no longer meet the demands of modern, high-assurance environments. These tools often lack support for mobile security, extensibility, and integration with mission-critical workflows, creating gaps in continuity, control, and user experience.

Mattermost replaces legacy, on-premises communication systems with a modern, sovereign collaboration platform built to support today’s security, compliance, and operational agility requirements.
