# domain reputation

A score or judgment of how trustworthy a domain is, built by security companies from signs such as its age, hosting, past behavior and presence on blocklists. Mail systems, browsers and firewalls use it to filter traffic. A poor reputation can stay with a domain after it changes hands.
