An application security course on running untrusted code somewhere whose loss you have already priced in. The isolation model as a concept and what each layer is actually for, network egress control argued as the property that decides whether a sandbox is useful or dangerous, the egress spectrum from fully closed to open and how to choose a position, the network attempt log as the primary analytical artefact, lifetime and teardown as controls, every place state can persist and which of them must not, getting an artefact in and a result out without reversing the boundary, the four jobs a sandbox does well, the record keeping that makes a result reproducible, governance and capacity, and the honest limits including what a clean run does not mean and the fact that a determined adversary treats an analysis environment as a target. Strictly defensive, and product detail is routed to docs.safeguard.sh and to your own tenant rather than asserted here.
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.
