ZAMA is a free data masking tool. Thales CipherTrust Application Data Protection is a commercial data masking tool by Thales Group. 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, company size fit, deployment model, here is our conclusion:
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.
Thales CipherTrust Application Data Protection
Teams protecting sensitive data embedded in application code,particularly those with strict separation-of-duties requirements between developers and security ops,should pick Thales CipherTrust Application Data Protection for its SDK-based encryption that keeps keys and policy enforcement out of application layers entirely. The tool handles both static masking and dynamic role-based redaction through a single centralized manager, letting you enforce data access rules without rewriting application logic. Not the fit for organizations needing database-level encryption or those whose developers expect a lightweight, self-service tokenization library; Thales demands infrastructure investment and close coordination between app teams and security.
Zama's fhEVM Coprocessor is an open-source tool for developing applications using Fully Homomorphic Encryption, enabling privacy-preserving computations in various domains.
