A course for the security manager who will be challenged on the numbers by people who are good at challenging numbers. It shows why finding counts, patch counts and training completion mislead, sets out the four properties a measure needs to survive a hostile question, and works through the measures worth keeping: time to remediate by severity and by distribution rather than by average, coverage with its unknowns, escape rate, recurrence, control health and exception ageing. It covers leading against lagging indicators, sampling and confidence when you cannot measure everything, definitions that cannot drift, and the gaming problem in detail, with the cheapest path to a better number and the counter signal for every measure taught. It closes on presenting a number that got worse for a good reason without losing the room.
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.
