Awarded for completing Transport and Internet Protocol Security Internals and passing its exam, demonstrating a precise, mechanism level understanding of TLS and IPsec sufficient to diagnose, configure and explain real protocol behaviour rather than treating it as an opaque checkbox.
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.
