Your installed programs, checked against every CVE on public record. Three steps, and the third one is just waiting a few seconds.
The scanner reads installed programs — never files, passwords, or personal data. You see the exact list before anything is sent, either way.
Results live at a random link only you hold. They are never listed publicly and are deleted after 30 days.
Download the scanner or paste a command’s output — whichever you’re comfortable with. No account, no background service.
