Awarded for completing DNS Security Fundamentals and passing its exam, demonstrating the ability to reason about DNS as a trust dependency, distinguish cache poisoning from registrar account hijacking, evaluate a DNSSEC deployment and its adoption limits, detect DNS used as a covert channel, and apply the hygiene and ownership practices that keep a DNS estate secure over time.
Certificates are designed to be checked, not just displayed.
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
