Mattermost introduces Sovereign Agentic Solutions: agents on customer-controlled open-weight models for air-gapped and classified networks

In one minute

Mattermost announced Sovereign Agentic Solutions on October 27, 2026.

What changed: Mattermost announced sovereign agent deployments using customer-controlled open-weight models in air-gapped and classified environments.

The offering is intended for air-gapped and classified environments and runs specialised agents on open-weight or on-premises models controlled by the customer.

Mattermost says agents can run from a data centre or edge deployment down to a laptop, under the platform's access policies and audit trail. Different agents can use different models: the company gives intelligence-report fusion and cyber-alert enrichment as examples. Cohere models through Cohere North are also listed as available for on-premises or fully air-gapped deployments.

The release further describes quantum-safe authentication with Arqit, Microsoft Teams embedding with GCC High support, Matrix/XMPP interoperability, and Kubernetes high-availability deployment. It says actions remain under human authority.

The announcement does not provide pricing, general availability terms, deployment counts, benchmark results, or independently verified security and operational outcomes.
