AI-powered sovereign air-gapped mission collaboration

Mattermost is built for security teams that need to govern collaboration the same way they govern the rest of their infrastructure. The platform runs inside your environment, on your terms, including air-gapped and sovereign deployments where data residency, jurisdictional control, and AI governance need to be settled at the architecture level. Our customers include national security organizations, regulated multinationals, and critical infrastructure operators across defense, intelligence, cyber, and financial services.

SPEAKING SESSION | Tuesday June 2, 2:45 PM

The Collaboration Layer Is the AI Risk No One Is Managing

Speakers: Dr. Bill Anderson, Principal Product Manager, and Leigh Dow, CMO

AI agents are being deployed into the collaboration platforms organizations already use, often before governance frameworks have caught up. This session covers why the collaboration layer is becoming the AI risk surface most security programs are missing, what sovereignty-first architecture changes about the answer, and the three questions every CISO should be asking their platform vendor before the next agent goes live.

Sovereignty, AI governance, and incident-time evidence are running through every audit conversation we hear. We will walk through where your collaboration stack does and does not line up with your control plane.
