CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Data teams that need to run analytics and machine learning on sensitive data without building separate sanitized datasets should evaluate Sarus. It enforces privacy policies directly on queries in real time and rewrites them automatically, which means analysts get usable results without exposing raw PII; the approach addresses both PR.AA access control and PR.DS data security in a single layer. Skip this if you're looking for a traditional data masking tool that handles structured PII in data warehouses; Sarus is built for hybrid query environments across SQL, pandas, and scikit-learn, which makes it heavier to deploy but far more flexible for modern analytics workflows.
