Use Case

Continuous Domain Security Monitoring

One-off scans miss changes between assessments. Domain security monitoring tracks your posture over time and alerts you when DNS changes, certificate renewals, or policy downgrades introduce new risks.

Common Questions

Why is one-off scanning not enough?
Domain security posture changes continuously. Teams add cloud services and forget DNS records. Certificates expire or are renewed with different settings. Mail providers change DMARC policies. A point-in-time scan gives you a snapshot; monitoring gives you continuous visibility and catches changes before they become incidents.
Does VP Shield offer ongoing monitoring?
The free VP Shield tool provides on-demand scans. VantagePoint Networks provides a managed domain security monitoring service with scheduled scans, alert notifications, and regular reporting. Contact us for pricing.
What events should trigger an immediate re-scan?
Scan immediately after: changing mail providers, migrating hosting, adding or removing subdomains, renewing or replacing SSL certificates, or any change to DNS records. These are the events most likely to introduce new misconfigurations.
