Duality Query vs enclaive Always Encrypted Nextcloud: Side-by-Side Comparison (2026)

Short answer

Enterprise and mid-market teams sitting on siloed datasets across jurisdictions or business units should evaluate Duality Query if your constraint is "data cannot leave its current location." Fully homomorphic encryption lets you query encrypted data in place without movement or replication, which solves a real compliance problem that traditional data warehousing cannot. The tradeoff is computational overhead; FHE queries run slower than plaintext equivalents, so this is for teams prioritizing privacy over query latency, not for analytics workloads demanding subsecond response times. Organizations handling sensitive data under GDPR or operating in regulated industries should choose enclaive Always Encrypted Nextcloud for its runtime encryption via Confidential Computing, which keeps files encrypted even during processing, not just at rest. The German data center residency plus zero-operator-access architecture directly addresses PR.DS and PR.AA controls without requiring your team to manage key infrastructure. Skip this if your primary need is ransomware recovery orchestration or you need multi-cloud flexibility; enclaive's strength is preventing unauthorized access entirely, not restoring from backups after compromise.
