The free scan shows every finding's score, severity, and dollar amount, plus one fully detailed example finding.

It does not create an account or upload your CSV.

The unlock stays active for this browser session on this device. Review or save what you need before closing the browser. For access that persists across devices and sessions, create an account instead.
