Frequently Asked Questions
Yes, Tresorit is fully HIPAA compliant and provides a Business Associate Agreement (BAA) for healthcare organizations. The zero-knowledge encryption ensures that patient data is protected end-to-end. Tresorit also complies with GDPR, SOC 2, and other regulatory frameworks required by healthcare, legal, and financial industries.
Tresorit costs more because it provides enterprise-grade security features that mainstream providers do not include. Zero-knowledge encryption, independent security audits, DRM controls, email encryption, and Swiss jurisdiction all add cost. For individuals storing casual files, it may be overkill. For businesses handling sensitive or regulated data, the premium is justified.
