What is Data Masking Software?
Data masking software is designed to protect sensitive information by replacing real data with anonymized, scrambled, or fictionalized values while maintaining usability for testing, development, or analytics. It ensures that personally identifiable information (PII), financial details, healthcare records, or other confidential data remain secure when shared outside of production environments. These tools apply techniques such as substitution, shuffling, encryption, and tokenization to preserve data format and integrity without exposing the original content. By safeguarding sensitive fields, data masking software helps organizations comply with privacy regulations like GDPR, HIPAA, and PCI DSS. It is widely used in industries such as banking, healthcare, retail, and government where strict data protection is required.

Velum Privacy
Velum Privacy
Velum Privacy masks personal data before it reaches an AI assistant, then restores the real values in the reply. Everything runs on your own machine. No servers, no accounts, no telemetry. Reversible by design: one-way redaction protects the data but breaks the answer. A local mapping means the reply comes back readable. Three surfaces, one engine. A browser extension for Chrome, Brave, Edge and Vivaldi, text masking free, no account. A macOS desktop app for documents, folders and coding agents over MCP, Windows in progress. A Jira and Confluence Cloud app that runs inside your own Atlassian instance. Detection combines pattern matching, checksum validation for IBANs and national IDs, and a local NER model across nine language variants. Accuracy is published, including failure rates: 99.8% must-mask F1 at the top tier. Verifiable, not asserted: the extension declares zero host permissions, and the desktop app names every outbound call and masks with the network off.Starting Price: $149/year -

Classify PII centrally, find it globally, and mask it consistently. Preserve realism and referential integrity via encryption, pseudonymization, redaction, and other rules for production and test environments. Delete, deliver, or anonymize data subject to DPA, FERPA, GDPR, GLBA, HIPAA, PCI, POPI, SOX, etc. Verify compliance via human- and machine-readable search reports, job audit logs, and re-identification risk scores. Optionally mask data as you map it. Apply FieldShield functions in IRI Voracity ETL, federation, migration, replication, subsetting, or analytic jobs. Or, run FieldShield from Actifio, Commvault or Windocks to mask DB clones.
