A working course on securing wireless networks and the Internet of Things (IoT) device population in an organisation's own environment, distinct from the vulnerability management practice used for managed laptops and servers. You will learn why this population has limited or no security agent capability, infrequent or absent patching, and is frequently procured outside any formal process, wireless network security fundamentals and genuine guest network isolation, device discovery as the first and hardest problem, default credential risk at realistic scale, network isolation as the practical primary control, firmware update management and its structural limits, the vendor cloud dependency that extends the trust boundary beyond the physical device, and building an inventory and policy for this population as an ongoing operational practice.
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.
