A platform owner's course on hardening Kubernetes workloads without breaking them, written for someone who owns the substrate every team ships on and cannot personally review any of it. You will work through the security context fields that matter and what each one actually prevents, the Linux capability model properly rather than as a list to copy, Pod Security Standards and admission as the enforcement point, and the real work of applying a policy to an estate that already violates it. It closes with tenancy boundaries, resource limits as a denial of service control, exceptions with expiry and the measurement that keeps a hardened estate hardened.
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.
