About

IRI CellShield® protects the sensitive information in your Microsoft Excel® spreadsheets, allowing you to comply with data privacy laws. Point-and-click to protect your columns with reversible and non-reversible masking functions. CellShield keeps your data secure, whether it's in one sheet or a million. Use multiple search methods to find and report on PII across the LAN, and protect it all at once. Classify and mask it in intuitive graphical dialogs. CellShield's core technology is built on the award-winning IRI FieldShield data masking product for databases and flat files. Data masked in one platform can be revealed in another. CellShield EE is the only full-featured, professional data discovery, masking, and auditing package for Excel 2010, 2013, 2016, and 2019 (plus Office 365) workbooks in your LAN. CellShield EE exceeds the security and scope of a single password by combining and automating all these extra capabilities.

About

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.
