Features, pricing, ratings, and pros & cons — compared head-to-head.
DataStealth On-Premise is a commercial data masking tool by DataStealth. eperi sEcure is a commercial data masking tool by eperi. Compare features, ratings, integrations, and community reviews side by side to find the best data masking fit for your security stack.
Based 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.
SMB and mid-market teams handling sensitive data across Microsoft 365 or Salesforce will find real value in eperi sEcure because it encrypts at the client before data ever touches the cloud, keeping encryption keys fully in your control rather than your vendor's. The GDPR, DORA, and NIS-2 compliance mappings are built in, and function-preserving encryption means your teams keep using these apps normally after deployment. Skip this if you need post-deployment searchability across encrypted data at scale, or if you're running heavy workloads across dozens of SaaS platforms beyond the tight Microsoft/Salesforce integration set.
