CloudMask E2EE for Education is a commercial data masking tool by CloudMask. Microsoft SEAL is a free data masking tool. Compare features, ratings, integrations, and community reviews side by side to find the best data masking fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Education institutions handling FERPA-regulated student data need CloudMask E2EE for Education because it encrypts sensitive information before it ever leaves your infrastructure, eliminating the risk that a compromised cloud provider or insider can access unencrypted records. Device-local key management and Common Criteria certification mean your encryption keys never transit through CloudMask's servers or anyone else's, which directly addresses the compliance posture FERPA auditors actually care about. This tool is overkill for districts primarily concerned with network segmentation and access controls; it's built for schools that have already experienced or narrowly avoided a cloud storage breach and want cryptographic certainty that student data stays opaque.
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.
