An architecture course on Zero Trust Network Access (ZTNA) as a replacement for traditional virtual private network (VPN) based remote access. You will learn why ZTNA grants access per resource rather than per network, how continuous verification and device posture combine into an access decision, how a phased migration is sequenced by risk, how ZTNA relates to microsegmentation, and the performance, user experience and selection factors that determine real world adoption.
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.
