About this extension
Defensible CUI Guard helps reduce accidental Controlled Unclassified Information leaks at the paste step in the browser.
What you get
• Paste guard — if text looks like CUI and the destination is risky, confirm before paste
• Copy reminder for marked content
• Editable allowlist and high-risk defaults (consumer AI, personal webmail, social DMs, pastebins)
• Break-glass: allow once or for the session when you mean it
What it does not do
• Does not stop screenshots, phone photos, retyped secrets, or desktop apps outside the browser
• Is not a full DLP suite and does not certify CMMC
• Matching runs on your device; v0.1 does not upload clipboard contents to Defensible Score servers
