One surface, three editor families, taken past the orientation that courses 92 and 124 give and past the practice that course 1002 and tutorial 306 already cover. It works through what the extension can see and at which moment it runs, the latency budget that decides what an in editor check can physically do, the honest limits of anything that only sees a file in a workspace, the workspace trust decision you should make before opening somebody else's code, what can leave the machine and how to establish the answer before adoption, the three permission systems that can refuse you, findings shown inline against findings that should escalate, tuning for signal without going silent, working offline, and the version drift that three distribution channels produce by default. Where a setting, menu or shortcut differs between editors and versions, the course teaches the decision and sends you to the current documentation rather than printing a path that may be wrong.
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.
