Cosmian Data Protection Suite vs Tresorit SecureCloud: Side-by-Side Comparison (2026)

Cosmian Data Protection Suite

Enterprise security teams protecting sensitive workloads in public cloud need Cosmian Data Protection Suite for its post-quantum encryption primitives, which competitors won't offer for another two years. The suite covers NIST PR.DS and PR.PS with encrypted key management and confidential computing enclaves that keep data encrypted even during processing, addressing the gap most DSPM tools leave in platform security. Skip this if your organization needs turnkey integration with existing DLP workflows or support for legacy on-premises infrastructure; Cosmian is cloud-native and cryptography-forward, not SIEM-friendly.

Tresorit SecureCloud

Teams protecting sensitive files across distributed workforces need Tresorit SecureCloud for its zero-knowledge architecture, which means your data stays encrypted even from Tresorit itself. The vendor's Switzerland headquarters and E2EE implementation directly address NIST PR.DS data security requirements without requiring trust in infrastructure providers. Skip this if you need deep integrations with major identity providers or conditional access policies tied to device posture; Tresorit's strength is encryption simplicity, not identity-layer controls.
