conclusion text: Choose Microsoft Teams if you're already invested in Microsoft 365, need enterprise-grade reliability with minimal setup, and prioritize feature breadth and integration depth. Choose Mattermost if you require self-hosted deployment, open-source transparency, data sovereignty control, or operate in regulated industries with strict data residency requirements.

main entity: Can Mattermost replace Microsoft Teams?
  type: Question
  accepted answer: Answer
    text: Mattermost can replace Teams for core messaging and collaboration needs, but Teams' advantages are significant: seamless Microsoft 365 integration (Outlook, SharePoint, OneDrive), larger participant video calls (10,000 vs 1,000), and built-in AI features via Copilot. Mattermost excels if you prioritize data sovereignty, open-source transparency, and cost control. For organizations heavily invested in Microsoft products, migration may not be cost-effective.
    language: en-US
main entity: Is Mattermost truly free to use?
  type: Question
  accepted answer: Answer
    text: Yes, Mattermost's self-hosted version is permanently free with no user limits under the Apache 2.0 license. However, free doesn't mean cost-free: you need in-house IT resources for server setup, SSL certificates, security updates, and maintenance. Organizations typically estimate $2,000-$10,000 annually in infrastructure and labor costs. Mattermost Cloud (managed hosting) starts at $10 per user/month.
    language: en-US
main entity: Which is more secure: Teams or Mattermost?
  type: Question
  accepted answer: Answer
    text: Both are secure, but differently. Teams offers enterprise-grade security (SOC 2 Type II, HIPAA, ISO 27018) with Microsoft's resources defending against threats. Mattermost's self-hosted model provides security through transparency: you audit the open-source code, control data location, and don't rely on third-party cloud infrastructure. For GDPR compliance and data residency requirements, Mattermost self-hosted offers superior control. For vulnerability management and zero-day protection, Teams' enterprise resources win.
    language: en-US
main entity: How does video conferencing compare?
  type: Question
  accepted answer: Answer
    text: Teams supports up to 10,000 participants with native HD recording, real-time transcription, and Copilot meeting summaries. Mattermost integrates with Jitsi (open-source) supporting ~1,000 participants with lower transcription features. Teams is superior for large webinars and enterprise meetings. Mattermost suffices for team calls but requires additional tools for large events. Teams also offers superior meeting intelligence and Copilot-powered insights.
    language: en-US
main entity: What are total cost differences for 500 employees?
  type: Question
  accepted answer: Answer
    text: Microsoft Teams Standard: 500 users × $12.50/month = $75,000 annually (plus potential Microsoft 365 licensing at $5-22/user). Mattermost self-hosted: ~$0 software + estimated $5,000-$15,000 annual IT maintenance. Mattermost Cloud: 500 × $10 = $60,000 annually. Mattermost is cheaper, but Teams' integration value may justify the cost for existing Microsoft 365 customers. Break-even occurs if you already pay for Microsoft 365 ($2,500-$11,000 for 500 users).
