CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, 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.
Developers building privacy-critical applications on public blockchains or untrusted infrastructure need fhEVM Coprocessor because it's the only open-source tool that lets you perform computations on encrypted data without decrypting it first, eliminating the exposure window entirely. The library supports arbitrary smart contract logic through Fully Homomorphic Encryption, meaning your data stays encrypted end-to-end in NIST Protect and Govern functions. Skip this if your team lacks cryptography expertise or you need a point-and-click masking tool for legacy databases; fhEVM requires developers to architect around encrypted computation from the ground up, not bolt encryption onto existing systems.
