"Zero Trust is not a journey where you have to spend a lot of money upfront before you can get started. In almost every case, you just need to use what you have better."

In this workshop-style episode of the Zero Trust Journey, Dr. Victor Monga sits down with Jason Garbis and Jerry Chapman from Numberline Security. They move beyond the theory to conduct a live Zero Trust assessment of a fictitious company, "Precision Dynamic Manufacturing" (PDM). From "sticky note" admin passwords to flat networks where CNC machines and Wi-Fi guests coexist, Jason and Jerry map out a practical, no-fluff roadmap to maturity.

IN THIS EPISODE, WE COVER:

• The ZTMM+ Framework: Why the standard CISA model needed an upgrade and how "Governance" acts as the critical glue across all five security pillars.
• The PDM Case Study: A deep dive into an SMB with 200 employees—evaluating the risks of an IT stack built by the "neighbor's kid" and how to secure it before a CMMC audit.
• MFA is Non-Negotiable: Jerry breaks down the journey from simple SMS codes to phishing-resistant authentication and why it’s the single most important move for identity.
• Stop Buying, Start Configuring: How to leverage your existing Microsoft Entra ID (Azure AD) stack to achieve Zero Trust principles without a massive capital investment.
• Network Segmentation for OT: Practical strategies for isolating "crusty" legacy hardware and CNC machines from the rest of the enterprise to stop lateral movement.
• Building External Trust: How a mature Zero Trust posture directly impacts your ability to secure cyber insurance and win contracts with security-conscious partners.
