Infrastructure as Code for DNS

Establish the Baseline.
Enforce the Standard.

Site Sentinel treats your DNS records like code. Establish a "Master State" that represents your source of truth.

The live internet is chaotic. Registrars change interfaces, employees make unauthorized tweaks, and attackers try to hijack subdomains. Site Sentinel acts as the immutable validator that ensures what the world sees is exactly what you defined.

  • Automated scheduled polling of authoritative nameservers
  • Cryptographic verification of record integrity
  • Detailed audit logs for every state change
  • Frictionless integration with CI/CD pipelines
