security.txt (RFC 9116) is a small text file that tells security researchers where to send reports. If someone finds a problem with your site and cannot find a contact, they often say nothing. This checker looks for the file and generates one for you.

No credit card. Only scan domains you own or are authorized to assess. PixelPrivate performs passive, public checks only.
