Identity, Device, Network, and Application can all say yes to a transaction, and it can still be the wrong call. This week's Zero Trust Foundations post closes out the Five Pillars with Data, and why data needs veto power over every decision, not just a seat at the table. Plus, big news: A Student of Truth is live on Amazon now, on sale for 90 days.

Devices used to mean laptops and phones. Now they mean containers, microservices, and AI agents that can act on their own. This week's Zero Trust Foundations post runs the AAVI model through the Device pillar, with real 2026 breach headlines showing what happens when device and workload trust gets skipped, whether the "device" in question has a keyboard or not.

Identity is where Zero Trust starts, but it cannot stand alone. In this post, we run AAVI through the Identity pillar by documenting transaction flows, writing Zero Trust policy statements, enforcing MFA, retiring legacy authentication, and showing how visibility, automation, and governance keep identity decisions honest.

Zero Trust works best when we stop trying to fix everything at once and start with one meaningful protect surface. This post explains how to choose that first surface, avoid common pitfalls, and use a practical checklist to make Zero Trust manageable with the tools and capabilities you already have.
