Zero Trust Security Fundamentals for IT Professionals
Learn Zero Trust Fundamentals: NIST Architectural Model, Pillars, Design, Migration, Use Cases, Maturity Models & More
Zero Trust has evolved from an emerging concept to the preferred security strategy for enterprise networks, systems, applications, devices, data, and cloud services. Following high-profile breaches like SolarWinds and the U.S. federal government's mandate requiring Zero Trust adoption, organizations worldwide are rapidly implementing Zero Trust architectures.
Whether you're a cybersecurity professional, IT practitioner, security architect, or business leader, understanding Zero Trust fundamentals is now essential for modern security strategy and implementation.
This course teaches Zero Trust as a security strategy and framework, not just a collection of technologies. You'll learn the NIST-aligned architectural model and gain the shared vocabulary needed to collaborate with technical teams and business leaders.


This course provides vendor-neutral coverage of Zero Trust fundamentals, architecture, and implementation strategy. Perfect for beginners and experienced practitioners alike who need to understand Zero Trust beyond vendor marketing.

"I really enjoyed this class. Alton provided me with exactly what I was looking for, a solid overview of Zero Trust that went well beyond just a surface-level-understanding, without committing me to several days worth of training. Alton has a very comfortable and relatable teaching style, and his overall content organization, flow, use of impactful graphics, inclusion of additional Resources, and the key-concepts excerpts were all extremely helpful. Definitely one of the best online classes I've ever taken!"
