Practical Usage

Monitor your SSL certificates and SSL certificate chain for any sign of tampering that could point to a potential domain or subdomain takeover.

Pinpoint which domains are worth trusting and which aren’t with data pertaining to their SSL certificates and SSL certificate chains.

Avoid domains with self-signed SSL certificates, which often get used or abused in man-in-the-middle (MitM) and typosquatting attacks.

Improve attack surface management endeavors by zooming in on domains with SSL certificates that are about to expire or already expired.

Stay abreast of SSL certificate and SSL certificate chain modifications, regardless how many times their domains change hands.
