An honest look at how the OWASP Top 10 is actually built and how it has changed across its editions: the difference between data-driven categories and community survey entries, why categories merge, rename and disappear, and a repeatable method for mapping an older finding to the current category. You will finish knowing the list's real value and its honest limits as a security programme, and where to check for the current edition rather than assume one.
Nothing. Every course, exam, and certificate on the catalog is free — including retakes. All you need is a free Safeguard account.
None. The flagship course, Safeguard Certified Practitioner, is a beginner-level course — basic familiarity with how software is built helps, but every exam question is answerable from the lessons themselves.
You can retake it after a 24-hour cooldown, as many times as you need. Retakes are free, and each attempt draws a fresh random set of questions.
The Safeguard Certified Practitioner credential is valid for 24 months from issue. The expiry date is printed on the certificate and shown live on its public verification page. Renewing means passing the current exam again.
