Overview

The Intelligent Mission Environment (IME)

Mattermost is an Intelligent Mission Environment (IME), purpose-built for mission-critical operations. It delivers a unified platform for secure, extensible, AI-powered collaboration and automation, deployable across the most demanding environments—from classified networks to the tactical edge. Organizations use Mattermost to maintain full control over communications, workflows, and infrastructure while accelerating decision-making.

IME integrates secure messaging, workflow automation, task management, and real-time communication within a sovereign, cyber-resilient architecture. It supports extensibility through open APIs and integrations, and runs flexibly across on-premises, cloud, and air-gapped systems—enabling operational focus, adaptability, and resilience from edge nodes to centralized data centers.

It is designed to meet the evolving needs of national security, defense, intelligence, cybersecurity, and critical infrastructure sectors for mission-critical workflows, including:

• Cyber Defense: Secure, out-of-band communications and automation for Security Operation Center (SOC)/Computer Emergency Response Team (CERT) workflows.

• DevSecOps: Sovereign Continuous Integration Continuous delivery (CI/CD), Information technology service management (ITSM), and digital system management at scale.

• Mission Operations: Collaboration across command, control, manufacturing, energy, and joint operations.

See the Use Case Guide to learn how operational teams use Mattermost to accelerate mission-critical work across a wide variety of disciplines.

Secure collaborative workflow

Built on an extensible open-core architecture, Mattermost offers an array of collaborative tools across managed Windows, Mac, or Linux desktop applications, secure web browsers with or without internet access, Bring your own device (BYOD) or mobile device management (MDM)-managed mobile, and embedded Microsoft 365 user experiences.

Messaging collaboration

Mattermost Channels enables secure, real-time and asynchronous communication across web, desktop, and mobile—powering mission-critical collaboration and Chat Operations (ChatOps) workflows across connected, hybrid, and air-gapped environments. Channels feature the following capabilities:

• Public and private channels, direct messages, and threaded conversations for structured operational coordination.

• Role-based access controls and audit logs to support need-to-know enforcement.

• Configurable notifications (e.g., alerts, keyword triggers, muting) to surface high-priority activity.

• Integrated ChatOps capabilities via slash commands, bots, and incoming webhooks for real-time automation and system alerts.

• Pinning, bookmarking, and advanced search to maintain continuity and context in high-volume environments.

• Cross-platform support on web, desktop, and mobile clients for flexible field to command and control access.

Workflow automation

Mattermost Playbooks standardizes and automates mission workflows such as incident response, shift changeovers, and operational checklists—reducing human error and improving procedural consistency. Playbooks feature:

• Structured checklists with assigned tasks and due dates to operationalize standard and incident or emergency operating procedures.

• Automated status updates and real-time notifications in linked channels to keep stakeholders informed of workflow progress or blockers.

• Embedded actions , assignments, and guidance for repeatable execution to ensure operational consistency.

• Timeline, retrospectives, and metric tracking for after-action reviews and accountability.

• Integration triggers (e.g., alerts from monitoring tools) to launch workflows automatically and decrease time to execution.

Audio and screenshare

Mattermost Calls enables real-time communication and troubleshooting through sovereign audio calling and screen sharing—supporting secure knowledge transfer and fast response in time-sensitive scenarios. Key capabilities include:

• Enables 1:1 and group audio calls directly within channels and direct messages, maintaining contextual awareness and access control based on channel membership.

• Supports secure screen sharing for visual coordination and analysis.

• Operates in sovereign, air-gapped, or sensitive network environments.

• Offers optional AI-based transcription and summarization for meeting capture and follow ups.

• Works across web, desktop, and mobile for flexible, secure access.

Project and task management

Mattermost Boards enables you to coordinate operational work with Kanban-style planning that integrates directly into messaging workflows—enabling transparency, prioritization, and accountability across teams with the following capabilities:

• Provides visual task boards with drag-and-drop cards and customizable workflows, supporting contextual awareness and role-based task visibility.

• Delivers real-time updates and synchronization with linked Mattermost channels.

• Supports card-level assignments, checklists, labels, and due dates for operational clarity.

• Enables filtering and sorting to manage backlogs, priorities, and forward planning.

• Maintains project visibility without requiring users to switch away from primary communication channels.

AI Agents and open APIs

Mattermost Agents accelerate decisions and streamline repetitive tasks with AI-driven assistance, fully controllable within sovereign infrastructure—offering intelligent support for both users and workflows:

• Provides configurable AI assistants that summarize threads, extract action items and answer questions with contextual insight and operational awareness.

• Supports direct interactions with AI agents in dedicated threads or channels.

• Enables semantic search using natural language to surface relevant content across Mattermost data.

• Supports Retrieval-Augmented Generation (RAG), custom instructions, and responsible AI guardrails for secure automation.

• Integrates with local models (e.g., Ollama, vLLM) and cloud LLMs via OpenAI-compatible APIs for flexible deployment.

Integrations and AI platform

The Intelligent Mission Environment (IME) is built for secure, extensible integration with mission-critical systems and AI workflows. Designed to operate in sovereign, regulated, and disconnected environments, IME supports modular automation, multi-agent orchestration, and the secure deployment of both local and cloud-based AI models—enabling faster decision-making while maintaining full control over data, infrastructure, and model behavior.

Layered extensibility

Built to integrate securely with complex enterprise and mission-critical environments, this model enables teams to tailor workflows, automate operations, and connect to external systems using open standards and modular components—supporting rapid deployment of automation while maintaining flexibility and compliance across both air-gapped and connected environments.

Key capabilities include:

• Secure video integrations: Embed secure video platforms such as Pexip, Webex, and Jitsi for sovereign mission collaboration.

• Pre-packaged and custom integrations: Quickly connect with systems like GitHub, GitLab, Jira, ServiceNow, Jenkins, and PagerDuty.

• Webhooks and slash commands: Enable real-time, event-driven automation and user-triggered actions directly from chat.

• Plugin architecture: Extend the Mattermost core with custom UI components, server-side logic, and third-party services.

Multi-Agent, Multi-LLM integration

A secure, extensible foundation for integrating multiple large language models (LLMs) and autonomous agents within a sovereign control plane enables organizations to operationalize AI within sovereign infrastructure—fusing data across systems, accelerating decisions, and maintaining full control over AI model access and performance. Organizations can leverage the following capabilities to operationalize AI:
