Data Guard

Masks sensitive data in ChatGPT, Claude and Gemini prompts and uploads before they are sent, and restores it in the answers.

Data Guard keeps sensitive details out of AI chat services. Before a prompt or a file reaches the AI service, Data Guard replaces personal details such as names and phone numbers with placeholders such as PERSON_1. When the answer comes back, the real values are put back in place, in your browser. • Prompts: type and send as usual. The prompt is masked before it is sent. • Files: attach a file the usual way. The AI service receives a masked copy, never the original. For spreadsheets you can choose which columns to mask. • Answers: placeholders in the answer are replaced with the real values automatically, or on demand. • Custom terms: add words that must always be masked. Data Guard is an internal tool for Jazz employees. It requires signing in to the Data Guard console with a Jazz Microsoft 365 account, and it works only on Jazz's network or VPN. Masking is done by Jazz's own Data Guard server; nothing is sent to any other company.
