DNS Security Hardening

Misconfigured DNS exposes your organization to attacks

❌ The Problem

  • Missing SPF/DKIM/DMARC enables email spoofing
  • Exposed DNS records reveal infrastructure details
  • Zone transfer misconfigurations leak sensitive data
  • Dangling DNS records enable subdomain takeover
  • No DNSSEC leaves you vulnerable to DNS hijacking
  • Inconsistent DNS across providers causes outages

✅ The Solution

  • Audit SPF, DKIM, and DMARC configuration
  • Detect dangling DNS records and subdomain takeover risks
  • Verify DNSSEC deployment and chain of trust
  • Check DNS propagation and consistency
  • Identify exposed sensitive records
  • Generate remediation recommendations
