# Certificates

SSL/TLS Certificates are a valuable source of information that are found on almost every web server on the internet. They can include information about your organization's network administrators, commonly used domain names (subject alternative names), and important dates for infrastructure updates. Certificates are commonly shared across many pieces of an attack surface, and you can select each individual certificate (which is uniquely identified by its fingerprint) to view all locations that certificate has been discovered.

Certificates are commonly found by completing a handshake with any servers identified to be using SSL/TLS and parsing the certificate that is received during that handshake.
