The Secure Alternative to MS Teams for Privacy-Conscious Companies

Stop compromising on privacy and security – switch to a GDPR-compliant communication solution with full data sovereignty.

Privacy Risks and Loss of Control with MS Teams

Microsoft Teams is established in many companies, but its use involves significant privacy and security risks. Sensitive company data is stored on foreign servers, while metadata collection and lack of end-to-end encryption pose additional risks.

Lack of Control Over Company Data

With MS Teams, your data is stored on Microsoft servers, which limits data sovereignty and can cause legal issues regarding GDPR.

Insufficient Encryption and Lack of Privacy

Microsoft Teams does not offer true end-to-end encryption for information exchange, and it collects extensive metadata.

Dependency on the Microsoft Eco System

Using MS Teams creates technological dependency and limits flexibility in IT infrastructure.
