Move at mission speed. Keep control of mission data.

National security and critical infrastructure teams need to share information and act quickly across coalition partners, networks and security boundaries. At the same time, access to sensitive data must reflect who is asking, what they are working on and the environment they are using. Mattermost brings communication and operational workflows into a customer-controlled environment, so teams can coordinate without making public-cloud connectivity the foundation of the mission.

More control over information. More ways to put it to work.

Data-Centric Security

Make classification visible across the user experience and apply attribute-based policies that take identity, organisational structure and operating context into account.

Cross-Domain Coordination

Connect collaboration across security domains through approved cross-domain infrastructure, with customer policies governing transfer.

Workflows and AI

Bring alerts, people and repeatable processes into a shared operational workspace. Open ecosystem with AI capabilities, with full audit trail and oversight throughout.

An ecosystem that comes to the mission

Under sovereign operations, vetted partner capabilities connect to the Intelligent Mission Environment and run inside the customer's infrastructure, completing the critical operational layer: information, people, workflows, and agents in one governed environment under the same, consistent access controls and practices.

From information to action, in a governed workspace.

An alert, update or request enters an authorised workspace. The team sees the relevant classification context, works within its access policies and coordinates the next steps. Connected systems and approved services can support the workflow while people review information and direct the response.

Built for the environments the mission demands.

Mattermost can be self-managed on-premises, in private, sovereign, and isolated clouds, and in networks with limited or no connection to the public internet. Customers control deployment, integrations and data handling according to their security requirements. v12 extends the platform's governance and cross-domain capabilities for teams working in those demanding environments.
