Awarded for completing The OWASP Top 10 Across Its Editions and passing its exam, demonstrating the ability to explain how the list is built, trace a finding across editions, and use it honestly as one input into a broader security programme.
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.
