A practical course on the specific and extremely common security risk created by an old, unpatched front end library such as jQuery still bundled in production. You will learn why these versions freeze in place, the cross-site scripting and prototype pollution vulnerability classes historically associated with this era of library, why front end risk is systematically easier to miss than backend dependency risk, how to build an inventory that finds every version actually in use across an estate, how to plan and test an upgrade across breaking changes, and how Content Security Policy and Subresource Integrity reduce consequence while that upgrade is pending.
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.
