For Security Teams

DNS posture for security teams.

DNS is part of your attack surface. Detect drift, reduce takeover paths, and keep authentication records correct — with evidence and a clear remediation trail.

Find dangling DNS and takeover risk

Identify dangling CNAME targets and other misconfigurations that create subdomain takeover paths. Attackers actively scan for these — you should too.

Detect risky record changes

Track changes to auth and security posture records so you can react before incidents. SPF, DKIM, DMARC, MX — all monitored.

Make evidence easy to share

Clear Pass/Warn/Fail outputs and copy/paste fixes reduce ambiguity across teams. Export reports for audits and compliance.

Issue	Impact	Fix
Dangling CNAME	Critical	Remove or update records pointing to decommissioned services

DMARC p=none	Medium	Upgrade to p=quarantine or p=reject after monitoring
No DNSSEC	Low	Enable DNSSEC at your registrar/DNS provider
