About this extension
A PAID GUARD.CH PLAN IS REQUIRED TO USE THIS EXTENSION. Without a paid plan you can still analyze links for free, directly on the guard.ch website.

Guard.ch opens a suspicious link inside a throwaway, instrumented browser in our cloud and records everything it does, so you can see what a link really is before you trust it.

With the extension you can:
- Right-click any link, or selected text that is a URL, and choose "Open in Guard.ch".
- Press a keyboard shortcut to investigate the page you are already on.
- Paste a URL into the toolbar popup, and optionally pick the server location it should leave from.

Every launch opens the link in a disposable cloud browser and takes you straight to the live investigation. The page runs far from your device while you watch. The extension stores no data, keeps no session, and signs no one in: it just opens Guard.ch in your own browser.

Available in English and German.
