The tools operators need aren’t available in every environment. At best, you have a swivel chair situation. At worst, you’re delayed and even blocked in your most critical moments.
Embedding Mattermost in Microsoft Teams lets you unify and share tools across mixed infrastructure while meeting granular data, classification, and access control requirements.
Integrate your critical tools into the workflows where your teams already operate
Mattermost integrated with Microsoft 365 extends secure collaboration beyond the reach of global infrastructure, bringing consistent and secure workflows, agility, and mission-critical communication to private cloud and disconnected environments. Operators get a unified operational picture from enterprise headquarters to the tactical edge, including air-gapped and DDIL environments where Microsoft alone can’t follow.
Mattermost extends your existing Microsoft Azure investment into IL5 and IL6 environments where standard cloud collaboration can’t follow. Built for teams needing data sovereignty, secure workflows, and consistent tooling across air-gapped and disconnected networks, it complements Microsoft solutions for high-security, intermittently connected operations.
Using Azure Arc and Foundry Local, data stays isolated and under your control, while Foundry-managed models bring local AI inference to accelerate mission-critical workflows—no cloud dependency required.
Security incidents produce sensitive data requiring strict access controls and a coordination channel separate from the systems under threat. Mattermost provides that environment: a segmented, out-of-band space with one-way sync from enterprise to edge, ensuring sensitive data never exits.
Pairing Mattermost with Microsoft blends the enterprise and high-security worlds with fine-grained control, information flow, and auditing so teams know where their data is and isn’t. Integrations with critical security tooling let operators automate signals from Microsoft Security Suite and third-party tools using Mattermost Playbooks for control, coordination, and reporting.
Interconnected environments with advanced information controls and sovereign AI.
Enable mission-critical coordination at the edge by deploying Mattermost in secure, on-prem, or air-gapped environments integrated with Microsoft Teams. Use Mattermost Cross Guard to synchronize data across classification levels and allied environments in a unified interface. Leverage Foundry Local to enable AI-powered workflows while keeping your most sensitive data under your strictest controls.
In August 2021, the US Air Mobility Command drove more on-time departures when 79.5% of personnel adopted Mattermost to enhance access to flight plans, routing, and operational communications.
Out-of-band incident response for Microsoft-centric environments.
Maintain operational continuity during global infrastructure incidents and in DDIL scenarios with a dedicated out-of-band instance for secure incident response. Achieve faster coordination, assessment, and resolution using collaborative Playbooks combined with the Microsoft Security Suite to evaluate, track, and audit a response from first signal to final report.
At NATO Locked Shields 2026, blue teams coordinated more than 150 operators against thousands of simultaneous real-time attacks using AI agents to assess alerts and accelerate responses.
Ship software quickly, securely, and efficiently.
Increase the focus and efficiency of developers, security engineers, and system operators starting at identity with Entra ID and extending through the SDLC with GitHub, Azure DevOps, Microsoft Defender, and more. Unify detection, evaluation, and response in a dedicated instance to isolate sensitive information while keeping the team working in one place.
A global media company switched to Mattermost for DevOps and business continuity to aggregate and resolve signals earlier in the process, preventing $100,000 per minute in potential losses.
Stay informed across environments without switching tools:
Eliminate the “swivel chair” and simplify user onboarding:
Access, share, and collaborate on files without leaving Mattermost.
Note: Integration delivered through an n8n or Zapier connector.
Centralize identity and access control across Mattermost and Microsoft.
Extend identity federation into classified and high-security environments:
Summarize ChatOps activity, generate courses of action, and auto-route incidents, all without prompts or outputs leaving your sovereign environment. Connect Mattermost workflows to Azure OpenAI Service for Azure Government or run local models with Foundry Local depending on your classification requirements. For Secret and Top Secret programs, Mattermost aligns with Microsoft classified clouds guidance to support secure deployment in any environment.
