Dangling CNAME checker
Find CNAME records that point at missing external services before they become domain takeover risks.
Frequently asked
What is a dangling CNAME?
A dangling CNAME points from your domain to an external service target that no longer exists or is no longer claimed. Some SaaS platforms let another account claim that target, creating a subdomain takeover risk.
Does every unresolved CNAME mean takeover is possible?
No. This tool separates generic unresolved CNAMEs from known SaaS provider patterns, and still treats findings as potential risks that need human confirmation before remediation.
