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.

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

• Meet global compliance mandates like GDPR and data localization laws by deploying Mattermost in public, private, or sovereign cloud environments tailored to national regulatory frameworks.
• Ensure full data control and transparency with self-hosted deployment options that eliminate exposure to vendor-controlled infrastructure or telemetry.
• Audit and enforce compliance behavior with role-based access controls, custom Terms of Service, and audit logging to align with internal and regulatory standards.
• Protect identity and access using SSO integrations, AD/LDAP synchronization, and MFA enforcement for secure authentication across geographies and operational roles.

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

• Create secure shared workspaces with Connected Workspaces Channels that synchronize discussions, reactions, and file sharing across trusted organizations—without exposing internal systems.
• Control access across organizations with attribute-based permissions and scoped identity policies to ensure mission alignment and sensitive information segmentation.
• Deploy sovereign AI and workflow automation in isolated environments using air-gapped AI operations and Collaborative Playbooks—enabling intelligence and speed without compromising data control.
• Upgrade legacy platforms like Skype for Business with modern, compliant tools for secure messaging, screen sharing, and team coordination. See Skype for Business replacement options.

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.

Benefits

• Modernize secure messaging and team coordination with channel-based collaboration, threaded discussions, and file sharing that work across web, desktop, and mobile.
• Replace outdated platforms like Skype for Business with a scalable, self-hosted architecture that delivers enhanced user experience, compliance, and cross-organizational flexibility.
• Protect sensitive information on mobile using enterprise-grade mobile security including biometric access, jailbreak detection, screenshot prevention, and remote wipe—ensuring secure access from personal or field-issued devices.
• Extend collaboration capabilities using integrated workflows and automations to replace manual coordination with policy-driven processes.
• Unify teams around a secure, customizable platform that evolves with your mission and integrates with internal systems via webhooks, plugins, and APIs.
