On October 16, Mattermost announced Mattermost Entry, a free, fully-featured evaluation tier for its Intelligent Mission Environment (IME). This self-hosted suite of tools—including workflow automation, project management, messaging, audio/screen sharing, and AI agents—replaces the prior basic messaging-only free offering, enabling rapid proof-of-value assessments in air-gapped, on-premises environments with complete data sovereignty to fortify against modern threats.
In the age of AI, data is under siege from cybercriminals and nation-state adversaries who breach multi-tenant infrastructures to steal secrets, extract IP, and disrupt operations. Third-party tools and AI systems pose increasing risks for harvesting proprietary knowledge for enhancement and resale to competitors—especially in free, SaaS editions, which exchange customer information and AI training for no-charge service. Additionally, evolving government regulations add risks of forced data handover to third parties, compromising sovereignty for governments, defense, and critical infrastructure organizations demanding resilient, self-controlled collaboration.
Mattermost Entry enables completely private collaboration and workflows—including project management, cross-platform messaging (web, desktop, mobile), workflow automation, and AI agents powered by fully on-premises sovereign AI models. No data leaves the organization’s perimeter, and no third-party risks exist. Administrators can verify that there is no external surveillance because they own and audit every aspect, directly countering data harvesting, IP extraction, regulatory handovers, and adversarial threats, while Mattermost has no access to customer environments.
“Most of the time, SaaS products and third-party apps are fine—they are the global norm,” said Ian Tien, CEO of Mattermost. “But for sensitive info like IP or national security secrets that adversaries covet, you need real-time chat, project management, or sovereign AI agents to guarantee no data leaves your perimeter. These high-rigor ops demand a mix of global and sovereign platforms, and Mattermost leads in unlocking sovereign AI collaboration with full data and operational control. Sovereign AI loses its value if third-party tools risk data leakage during team interactions.”
The free, self-hosted Mattermost Entry offering unlocks sovereign, on-premises AI workflows in multi-user/multi-LLM setups connecting to government and enterprise-hosted models (open-source like Llama or Mistral, proprietary like Cohere) or global ones (ChatGPT, Gemini, Claude, Grok). It powers cyber defense (incident response, threat hunting), DevSecOps (CI/CD, outage mitigation), and mission operations (command and control, industrial systems) with advanced controls like attribute-based access, SSO, audit logging, and high availability—all under full enterprise control to safeguard operations from breaches and extractions.
