3 privacy-focused, GDPR-compliant alternatives
Slack is owned by Salesforce, a US corporation subject to the CLOUD Act. Every message, file, and conversation in your Slack workspace is stored on US servers and potentially accessible to US authorities. For European organizations handling confidential communications, EU-based team chat alternatives provide equivalent collaboration features with data stored exclusively in Europe.
500+ government agencies chose Wire for a reason. Slack-like collaboration meets true end-to-end encryption. Swiss-based. Self-host on your servers if you want. Independent security audits confirm what we claim.
The French government uses it. The German military uses it. Mozilla uses it. Built on Matrix, the only truly decentralized messaging network. No vendor lock-in. Federate with others or run your own server.
No phone number or email required for signup. Complete anonymity by design. Swiss-made, open-source, independently audited. 11 million users. Collects no metadata about your conversations.
Slack offers GDPR compliance tools, but as a US-owned service (Salesforce), it remains subject to the CLOUD Act. EU alternatives like Element, Rocket.Chat, or Wire offer stronger data sovereignty with self-hosting options or EU-only data centers.
