DataFence - Data Loss Prevention

Protect sensitive data from unauthorized uploads. Monitor and block file transfers in real-time.

**What's New in Version 1.1.5** Allow-Listed Domains Fully Respected - Domains your organization allow-lists are now completely bypassed — no content analysis and no alerts on trusted sites, for both file uploads and text. - Domain matching hardened so a heavily-loaded page can't momentarily treat an allow-listed site as monitored. Stronger Text & Paste Protection - Pasted sensitive data is now caught before it appears — across ChatGPT, Google Gemini, Claude, Grok, Slack, and any site with a rich text editor. - Closed a gap where quickly typing sensitive data and pressing Enter could send it before it was checked. The send is now paused and blocked when needed. - Advanced document editors (such as Notion) are covered safely — sensitive content is blocked from being sent or saved, and never altered behind your back. Universal Coverage - Sensitive-text protection now works by default on any website with a rich text editor — not just a pre-approved list of sites. File Upload Hardening - Blocked files can no longer slip through via automatic background retries — once a file is blocked, none of it leaves the browser. - Drag-and-drop into AI tools (ChatGPT, Gemini, Claude, Mistral) is now held and checked before the file can land in the composer or reach the model. - File-picker and multi-step uploads are fully covered — a blocked file is stopped across every upload step, not just the first. - Classic web-form file uploads are now blocked before the file leaves the browser. - Safer by default: if a safety check can't finish in time, the upload is stopped rather than allowed through. Reliability & Fail-Safe - Outdated tabs now show a clear "Page Outdated — please refresh" notice and stay protected until refreshed. - Advisory warnings now appear once per session for the same content (e.g. a pre-filled email signature), and block/warning notices stay on screen until dismissed instead of flashing away. - Monitoring stays active through temporary startup hiccups.
