Our pick for a European buyer: Stackfield. We weight data residency, GDPR and EU jurisdiction above everything else — that is the constraint this directory exists to solve.

Frequently asked questions
Where is my data stored with Stackfield vs. Microsoft Teams?
Stackfield stores all data on servers in Germany, ensuring EU-only data residency and full control over data sovereignty. Microsoft Teams uses global data centers, including EU locations, but relies on Standard Contractual Clauses and the EU-US Data Privacy Framework for cross-border data transfers, which may still expose data to US jurisdiction under the CLOUD Act.
How do the two tools differ in terms of DSGVO compliance?
Stackfield is designed for DSGVO compliance by default: end-to-end encryption (AES-256) ensures that even Stackfield cannot access user data, and all processing stays within the EU. Microsoft Teams offers DSGVO features like audit logs and data retention policies, but compliance depends on correct configuration and may be affected by US data access laws.
Which tool is more cost-effective for a small or medium-sized business?
Microsoft Teams is often more cost-effective for SMBs, especially if they already use Microsoft 365, as it’s included in many plans. Stackfield has no freemium tier and is priced higher, reflecting its focus on security and integrated project management, but may be worth the cost for teams prioritizing data sovereignty and encryption.
Can I migrate from Microsoft Teams to Stackfield easily?
Stackfield offers migration tools and support for importing data from Microsoft Teams, including chats, files, and tasks. However, due to differences in architecture (e.g., encryption models), some manual adjustments may be needed, particularly for complex workflows or third-party integrations that Teams relies on.
Who should choose Stackfield, and who is better off with Microsoft Teams?
Stackfield is best for European businesses that handle sensitive data and need strict control over data residency, encryption, and DSGVO compliance. Microsoft Teams suits larger organizations or those already using Microsoft 365, where cost efficiency, broad integrations, and scalability are priorities, provided they can manage compliance risks.
