DNS Tool for Azure
DNS Tool for Azure is a SaaS DNS monitoring and security platform built exclusively for Azure DNS. It continuously scans your Azure DNS zones — public and private — for changes, misconfigurations, security risks, and certificate issues, and alerts you before problems become incidents.
Available on the Azure Marketplace.
What is DNS Tool for Azure?
DNS Tool for Azure connects to your Azure subscriptions via Entra ID and monitors every DNS zone and record across your environment. Unlike generic DNS monitors, it understands Azure-specific infrastructure: Private DNS zones, VNet links, Private Endpoints, and Azure resource correlation.
Key Features
- Zone & record discovery — Automatic inventory of all public and private DNS zones across your Azure subscriptions
- Change tracking — Record-level change history across your DNS zones
- Health scoring — Overall DNS health score with actionable findings for SPF, DMARC, DKIM, CNAME integrity, and more
- Azure Private DNS — VNet link audit, Private Endpoint DNS validation, duplicate zone detection, and orphan zone detection (Pro and above)
- Certificate monitoring — Certificate expiration tracking, inventory per domain, and CT log monitoring
- AI risk scoring — Automated risk scoring for DNS changes to prioritize review effort (Pro and above)
- Security checks — DNSSEC status, RBAC permission visibility, unauthorized CA detection, and CAA record auditing
- Alerting — Email, webhook, Microsoft Teams, and Slack notifications with per-record-type filtering
- MSP support — Multi-tenant dashboard with Azure Lighthouse integration and per-customer read-only portal
