DNS record change monitoring
Unauthorized DNS changes can break email delivery, hijack traffic, or signal a compromise. Harbor compares every DNS scan to your domain's previous snapshot and records what changed—so you can react quickly.
What we watch
Each scan captures mail authentication (SPF, DKIM, DMARC), MX routing, and authoritative name servers. When any of that data differs from the last successful scan, we store a structured diff.
How you get alerted
In Settings, connect a Discord webhook and enable DNS record changes. You'll receive a message listing what changed—without waiting until something breaks silently.
Why it matters
- Spot accidental edits from DNS providers or IT changes before email stops flowing.
- Detect suspicious NS or MX changes that could indicate takeover or misconfiguration.
- Keep an audit-friendly history in your Harbor dashboard alongside the rest of your security monitoring.
