Blanktick makes the unchecked part of a security scan visible

Field notes

The site describes 88 checks in total, but says the eligible set varies by platform and that some checks may still go unanswered on a particular device. Its example Windows 11 scan reports 50 checks run and 31 not checkable, with reasons listed; the displayed score is calculated only over the checks that ran. For selected files, the page says it calls Defender’s command-line scanner with remediation disabled.
