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 protecting sensitive workloads from insider threats and memory-based attacks will find Anjuna Seaglass valuable because it encrypts data in-use via hardware enclaves, not just at rest or in transit. The no-code wrapping approach means you can move existing containerized apps into Confidential Containers without rewriting application code, and multi-cloud deployment across AWS, Azure, and GCP reduces vendor lock-in. This is not for teams whose primary concern is preventing initial compromise or lateral movement; Seaglass assumes the container already runs and focuses on what happens inside it, leaving your CNAPP and network detection work largely unchanged.
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.
