Close the doors, one by one.

Driven by what your scan found. Work the high-severity doors first; each finished door shrinks your blast radius on the scan page.

Every known door from your last scan is closed. Keep watching — new leaks surface over time. Re-scan →

Why a checklist instead of a button?why?

Beta. This guides you; it cannot perform the steps for you and does not verify them — checking a box records your own progress. Both your scan and your lockdown progress are saved only to this browser (localStorage); nothing about you is sent to or stored on a server. No outcome is guaranteed — closing doors lowers risk, it does not make you "safe."
