A working course on the service mesh as a security control point: a dedicated infrastructure layer that enforces authentication, encryption, and traffic policy for service-to-service communication consistently, separate from each service's own application code. You will learn the sidecar proxy pattern and the data plane, why the control plane is a high-value target with a materially larger blast radius than any single sidecar, mutual Transport Layer Security (mTLS) and the automatic certificate issuance and rotation that makes it practical at scale, workload identity as the foundation for reliable traffic policy, the honest operational cost of running a mesh, and how to decide on and carry out adoption incrementally rather than through a disruptive all-at-once cutover.
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.
