Stackfield vs Slack — FAQ
Is Slack GDPR compliant?
Slack may offer GDPR compliance features and EU data residency options, but as a US-headquartered company, it remains subject to the US CLOUD Act and FISA Section 702. These laws can compel US companies to hand over data regardless of where it is stored. The EU-US Data Privacy Framework provides some safeguards, but its predecessors (Safe Harbor and Privacy Shield) were both invalidated by the European Court of Justice. Stackfield, as a European company, is not subject to these US laws at all.
How does Stackfield compare to Slack in features?
Stackfield offers End-to-end encryption, Task management, Video calls, Document collaboration, and 4 more features. While Slack's ecosystem may be larger due to its market position, Stackfield covers the core functionality that most teams need. The trade-off is typically between breadth of integrations (Slack) and data sovereignty with regulatory certainty (Stackfield).
Can I migrate from Slack to Stackfield?
Yes. Most European software providers, including Stackfield, offer migration tools or documentation to help you transition from US-based services. Under GDPR Article 20, you have the right to data portability — meaning Slack must provide your data in a machine-readable format. The migration process varies in complexity depending on your data volume and integrations, but for most teams it can be completed within a few days to a few weeks.
