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 handling regulated multi-party data collaboration will find real value in Anjuna Northstar because it eliminates the false choice between data utility and isolation, letting you share sensitive datasets without decryption or moving data to untrusted environments. The platform covers PR.DS and PR.AA in NIST CSF 2.0 through hardware-backed confidential computing, meaning access control and data protection are enforced at the CPU level rather than relying on network perimeter or encryption key management alone. Skip this if your primary need is internal data governance within a single organization, or if your workloads can't tolerate the latency overhead of attestation and enclave setup.
Cryptography teams and researchers building privacy-preserving applications need Microsoft SEAL because homomorphic encryption lets you compute directly on encrypted data without ever exposing plaintext, eliminating a whole class of data exposure risks. The library supports BFV and CKKS schemes across Windows, Linux, and macOS with active maintenance reflected in its 3,862 GitHub stars and regular updates. Skip this if your organization needs a turnkey data masking product with UI-driven policies; SEAL requires deep cryptographic expertise and development resources to implement correctly.
