Domain and DNS Monitoring Agent
Tracks domain registration, DNS record integrity, and resolution health across all company domains, alerting before expirations, hijacks, or misconfigurations cause outages.
Companies often manage dozens to hundreds of domains across multiple registrars and DNS providers, and a single expired registration or an accidentally deleted DNS record can take down a critical service or email flow with almost no warning
Domain expiration dates and DNS configurations are rarely tracked centrally, so renewal reminders depend on registrar emails that get missed, and unauthorized DNS changes from compromised accounts can go unnoticed for hours
Manually auditing DNS records for correctness, checking for dangling records that create subdomain takeover risk, and verifying SPF/DKIM/DMARC email authentication records is tedious and easy to defer indefinitely
This agent continuously monitors domain registration status, DNS record integrity, and resolution health across every company domain, alerting immediately on expiration risk, unauthorized changes, or misconfigurations that create security exposure
The agent maintains an inventory of all company-owned domains and their registration expiration dates, polling registrar APIs for status changes and expiration proximity. It continuously queries authoritative DNS servers to compare current records against a baseline configuration, flagging unauthorized changes, dangling CNAME records pointing to unclaimed resources, and email authentication record gaps. Findings are alerted immediately with severity based on risk (e.g., expiration within 14 days is critical), and a compliance dashboard tracks domain and DNS health across the portfolio.
Inventory and Monitor Domains
- Maintain a complete inventory of company-owned domains and registrars
- Poll registrar APIs for registration status and expiration dates
- Track domain ownership and administrative contact accuracy
- Flag domains nearing expiration on an escalating timeline
Validate DNS Record Integrity
- Query authoritative DNS servers and compare against baseline records
- Detect unauthorized or unexpected DNS record changes
- Identify dangling records pointing to decommissioned resources
- Verify SPF, DKIM, and DMARC email authentication records
Check Resolution Health
- Test DNS resolution from multiple geographic vantage points
- Monitor DNS response time and propagation consistency
- Detect resolution failures or inconsistent results across resolvers
- Flag potential DNS hijacking or cache poisoning indicators
Alert and Report
- Send immediate alerts for expiration risk, unauthorized changes, and hijack indicators
- Escalate critical findings through paging systems
- Generate a domain and DNS health report for IT and security leadership
- Track renewal and remediation completion over time
