CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise teams handling sensitive analytics or machine learning on regulated data will get the most from Vaultree Data-In-Use Encryption because it eliminates the decryption step entirely, reducing your attack surface where data breaches actually happen. The tool's fully homomorphic encryption lets you run queries and train models on encrypted data without ever exposing plaintext, and its cryptographic audit trails map directly to NIST PR.DS and ID.AM requirements. Skip this if your team lacks crypto expertise or needs to process unstructured data at scale; the performance overhead and implementation complexity aren't worth it for basic column-level masking use cases.
Mid-market and enterprise teams protecting sensitive data across fragmented infrastructure,on-prem databases, cloud APIs, legacy mainframes, and SaaS together,should evaluate DataStealth for its agentless inline masking that actually works across those disparate environments without forcing rip-and-replace. The platform covers all four NIST asset and data security functions (ID.AM, ID.RA, PR.DS, DE.CM) and deploys via gateway or proxy rather than requiring agents on every system, which matters when you're dealing with air-gapped or mainframe systems that block typical tooling. Skip this if your primary concern is detection and response; DataStealth prioritizes classification and protection over behavioral anomaly hunting.
