What is a Parked Domain?

This report explains parked domains—registered domains with no active website or email—and why they increase an organization’s attack surface. It outlines common parking types (registrar placeholders, monetized pages, sale listings, addon/alias misconfigurations), the security risks they pose (forgotten domains enabling takeover, stale DNS and certificate issues, typosquatting and brand impersonation, third‑party vendor risk), how SecurityScorecard detects and monitors parked domains, and recommended mitigations including centralized inventory, automatic renewals and locking, proper DNS/SSL/email configuration, redirects or decommissioning, continuous monitoring, and use of managed services for large portfolios.
