In today’s digital workspace, communication tools like Microsoft Teams are at the heart of productivity. But as organizations rely more on video meetings, chat platforms, and collaboration tools, a critical question arises: Who controls your communication, and more importantly, your data?

Challenges that go beyond data privacy

Communication tools sit at the heart of how organizations work. As teams are often spread across locations and more of that work moves to video, chat, and shared files, the question of who controls the data underneath becomes harder to ignore. For organizations that rely heavily on Microsoft Teams for collaboration, common concerns include:

• Data privacy and compliance risk
• Vendor lock-in
• Service shutdowns or forced migrations
• Fragmented tools across messaging, meetings, and file sharing
• External communication with partners and customers
• Hybrid and remote work needs

Nextcloud Talk addresses these challenges by providing a secure, integrated communication platform that puts you back in control. It consolidates all essential functions for efficient collaboration into a single application, while ensuring full data control and independence.

On the terms of functionality, control, and trust, how does Nextcloud Talk compare to Mircrosoft Teams for organizations that want to take back control over their data?

1. Advanced collaboration covering every work scenario

Nextcloud Talk is designed to bring communication and collaboration together in a single, secure platform.

Fully integrated into the broader Nextcloud ecosystem, it combines chat, video calls, and webinars together with file sharing and document editing within a single application, supported by advanced AI-driven features designed to simplify daily workflows.

Whether deployed on-premises or in a trusted environment, Nextcloud Talk gives organizations full control over their data while maintaining a modern user experience.

Use Case #1: Team Chat

Nextcloud Talk enables real-time messaging with features designed for productive teamwork. These capabilities help teams stay aligned and organized, even in complex projects.

Use Case #2: Video Meetings

For synchronous communication, Nextcloud Talk provides a robust video meeting experience which can adapt to a wide range of organizational needs.

Use Case #3: Webinars & Training

Nextcloud Talk supports webinars and training sessions, making it suitable not only for internal collaboration but also for external communication and knowledge sharing.

2. The ultimate base for team management

While Nextcloud Talk is known as a secure alternative for team chat and video calls, the real structural powerhouse of Talk lies within Nextcloud Teams. This is where Nextcloud moves beyond simple chat rooms and into an organizational replacement for Microsoft Teams.

Key features of Nextcloud Teams:

• Overview over projects and teams: Nextcloud Teams give you a great overview over your working groups, let it be departments, projects, sub-teams and so on, making it easy to quickly find exactly what and who you need without hunting through folders and private chats.
• Contextual communication: From the Nextcloud Teams view, you can instantly launch a Talk conversation, start a video call, or share a file with your group.
• Unified group management: There is no manual overhead in Nextcloud Teams. If a new employee is added to the “Sales Engineers” group in your organization, they automatically appear in the Sales Engineers Team in Talk, complete with access to relevant files and past conversations.
• Deep file integration: Every team has a direct link to their shared folders, allowing you to move from a conversation about a document to editing that document in Nextcloud Office with a single click.

While Nextcloud Talk is your primary driver for daily communication, Nextcloud Teams is the backbone that holds your company’s structure together, where you experience the structured “Channels” experience of Microsoft Teams while maintaining the privacy and speed of a self-hosted platform.

3. Security and compliance by design

Security is built into the core of Nextcloud Talk:

• End-to-end encrypted calls for maximum privacy
• Full control & ownership over data through self-hosting
• Access controls for enhanced security
• Compliance with local privacy regulations
• Protection from unauthorized access or breaches

By avoiding reliance on third-party cloud providers, organizations can protect sensitive data and reduce exposure to external risks.

4. Trusted solution for mission-critical setups

For governments and public institutions, data sovereignty and compliance are critical. Organizations such as the German Federal Government and the French Ministry of Interior rely on Nextcloud to ensure that sensitive data remains under their control while enabling modern collaboration. In these environments, the ability to deploy on-premises and avoid external dependencies is a key requirement.

A better alternative to Microsoft Teams

While many companies and organizations rely on tools like Microsoft Teams, growing concerns around data control and vendor dependence are driving the search for more sovereign alternatives. For those that prioritize digital sovereignty, compliance, and control over their communication stack, Nextcloud Talk takes a different approach:

• Full data ownership: Keep your communication data on infrastructure you control, on-premises or with a trusted provider, ensuring compliance and sovereignty.
• No vendor lock-in: Built on open-source technology, Nextcloud Talk gives you the flexibility to adapt, integrate, and scale without being tied to a single ecosystem.
• All-in-one collaboration: Team chat, video meetings, and file sharing come together in one platform, fully integrated with your workflows, reducing complexity and improving productivity.

Nextcloud Talk stands out because it combines data sovereignty, open-source flexibility, and fully integrated collaboration, without locking organizations into a single ecosystem.
