A course about automated reviewers, taught with the limits first, because an inflated model of what a bot catches is what stops people performing the checks it does not cover. It separates what such a tool genuinely finds, namely mechanical defects, known patterns, checks missing relative to a local convention and convention drift, from the four categories that are structurally out of reach: business logic, authorisation intent, the requirement nobody stated and the behaviour the code does not have. It then works the false confidence problem where a clean pass reads as an approval, the noise economics that decide whether engineers read the comments at all, whether a bot may approve and the narrow mechanical exemption if so, the governance questions when the reviewer is itself a model, the permissions such a component should and should not hold, and how to measure it by what it changes rather than by what it says. It closes on the honest case, which is usually the attention freed rather than the defects found, and the four conditions that have to hold for that attention to be worth anything.
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.
