The Future of Multi-Domain Secure Operations
Mattermost has officially expanded its Intelligent Mission Environment with the launch of Mattermost Enterprise Advanced.
This new product tier is specifically designed to meet the rigorous security and resilience requirements of multi-domain operations, joining the existing Mattermost Professional and Enterprise lines.
Enterprise Advanced offers a comprehensive messaging and collaboration platform across web, desktop, and mobile devices.
It integrates seamlessly into modern and legacy toolchains while providing advanced customization, security controls, and quantum-secure communications aligned with DoD Zero Trust standards.
Solving the “Hard Problems” in Mission Collaboration
Standard enterprise tools often fail to handle the complex challenges of multi-domain operations. Mattermost Enterprise Advanced solves these “hard problems” directly:
- Control Classified Data: Manage access precisely within multi-user environments.
- Enforce Need-to-Know Access: Lock specific channels and files based on program clearance levels.
- Mitigate Data Spillage: Deploy rapid tools to contain and handle data leaks efficiently.
- Connect Global Teams: Link authorized users securely across different organizations, countries, and languages.

Uncompromising Security and Compliance
The Enterprise Advanced security architecture protects mission-critical data through three core pillars:
1. Policy-Based Zero Trust
Administrators gain highly granular access controls for resources based on user properties, device health, and network data. The system integrates with User Authoritative Source databases to verify clearance levels automatically. Admins can manage these policies via simple drop-down editors or powerful expression languages.
2. Automated Data Spillage Handling
The platform includes features that maintain strong operational security. If a user improperly shares classified data in an unclassified channel, any user can flag the post. Mattermost immediately removes the content and sends it to a security review team with a full audit trail.
3. Post-Quantum Security & E2EE
Mattermost is adding support for NIST post-quantum-secure cryptographic algorithms to future-proof your data. Additionally, uncompromising end-to-end encryption (E2EE) ensures that only participants can read private group messages and encrypted channels—preventing even system administrators from accessing the content.
Resilience for Challenging Environments
Mattermost Enterprise Advanced is engineered to function in the most difficult conditions,
including air-gapped and DDIL (Disconnected, Degraded, Intermittent, and Limited) environments:
- Shared Channels: A highly resilient architecture allows servers to serve local users while disconnected and then resynchronize once connectivity is restored.
- Microsoft Teams Integration: The platform can act as an independent, reliable communication fallback that continues to work even if Microsoft Teams goes down.
- Automatic Channel Translation: Multinational teams can collaborate effectively, as every user can read and write in their own language within large channel discussions.
Enterprise-Grade Scalability and Support
Designed for massive scale, Enterprise Advanced supports up to 200,000 concurrent users and features a horizontally scalable architecture.
It supports zero-downtime upgrades and can be deployed on-premises or in cloud environments like AWS and Azure.
To ensure operational success, it is available with Enterprise Support (24/7 coverage with a 4-hour response target) or Premier Support, which adds private support channels and direct access to senior engineers.
