DataStealth On-Premise is a commercial data masking tool by DataStealth. StratoKey Cloud Data Encryption is a commercial data masking tool by StratoKey. 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:
Mid-market and enterprise teams protecting sensitive data in air-gapped or heavily regulated environments should pick DataStealth On-Premise for its ability to enforce field-level masking and tokenization without sending data outside your infrastructure. The inline gateway and sidecar deployment models work across SQL, NoSQL, Kafka, and Kubernetes, so you're not rebuilding policy for every data store; BYOK and on-prem HSM integration mean keys never leave your network. Skip this if your data lives primarily in SaaS platforms or you need a lightweight, API-first masking layer; DataStealth is built for teams managing their own infrastructure and willing to maintain a stateful proxy tier.
StratoKey Cloud Data Encryption
Mid-market and enterprise teams storing sensitive data in SaaS applications should evaluate StratoKey Cloud Data Encryption if field-level encryption before data leaves your network is your priority. The gateway architecture enforces FIPS 140-2/140-3 AES 256-bit encryption at the application layer, and BYOK/HYOK key management keeps encryption keys under your control rather than the vendor's. Skip this if you need post-encryption detection and response; StratoKey protects data in transit and at rest but doesn't monitor how encrypted data is accessed or exfiltrated once stored.
