A working course for the developer who lives in the terminal, taken past the surface tour that courses 47 and 124 already give you. It covers how the single static binary gets onto a machine and how you prove you got what you asked for, what the product means by one signed build across three surfaces, how the tool authenticates and what that credential is allowed to do, what it leaves on your disk and who else can read it, output for humans against output for machines, exit codes and gates that fail in the safe direction, proxies and certificate interception, offline and air gapped operation, what ends up in a build log forever, upgrading without breaking a pipeline, and the security of the tool itself including what it reads from your working directory. Where a flag or a path is not confirmable on a Safeguard surface, the course teaches the decision and sends you to the current documentation rather than guessing.
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.
