ClipQuarantine

ClipQuarantine is a desktop app (Windows + macOS) that prevents accidental data leaks through copy/paste—one of the most common, under-protected exfiltration paths. It runs as a lightweight agent that classifies clipboard content in real time (API keys, customer PII, source code snippets, internal URLs, secrets) and enforces policy when users paste into risky destinations like browsers, chat apps, ticketing tools, or personal email. Admins can set rules by app, domain, data type, and user group, with options to block, warn-and-justify, or auto-redact (e.g., mask all but last 4). It includes audit logs and privacy-safe telemetry (hashes/metadata, not full content) to support compliance and incident reviews. Realistically, it won’t stop a determined insider, but it will dramatically reduce accidental leakage and “oops” pastes that cause most day-to-day incidents.
