CST VerdictShort answer
Developers and security teams building applications that need lightweight data masking without infrastructure overhead should reach for Data Protection and Cryptography. The free pricing and 630 GitHub stars signal active use in production environments where byte-level manipulation of sensitive data needs to happen inside application code rather than in a separate gateway. Skip this if your requirement is policy-driven data discovery across your entire data estate; this tool assumes you already know what to mask and where. 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.
