CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
SMB and mid-market teams handling sensitive data across Microsoft 365 or Salesforce will find real value in eperi sEcure because it encrypts at the client before data ever touches the cloud, keeping encryption keys fully in your control rather than your vendor's. The GDPR, DORA, and NIS-2 compliance mappings are built in, and function-preserving encryption means your teams keep using these apps normally after deployment. Skip this if you need post-deployment searchability across encrypted data at scale, or if you're running heavy workloads across dozens of SaaS platforms beyond the tight Microsoft/Salesforce integration set.
