"Trust is a vulnerability. Zero Trust is a mindset that assumes the network is already hostile."
The traditional "castle-and-moat" security model—where everything inside the network is trusted—is dead. With the rise of remote work, cloud migration, and BYOD, the perimeter has dissolved. Enter Zero Trust.
Core Principles of Zero Trust

{ title: "Use Least Privilege", desc: "Limit user access with Just-In-Time and Just-Enough-Access (JIT/JEA) to minimize the blast radius of a breach." },

Five Steps to Implementation
- Define Your Protect Surface: Identify your most critical data, applications, assets, and services (DAAS).
- Map the Transaction Flows: Understand how sensitive data moves across your network to determine where controls are needed.
- Architect a Zero Trust Network: Customize the network based on the protect surface, creating micro-segments around critical assets.
- Create Zero Trust Policy: Base access rules on the "Who, What, When, Where, Why, and How" of the request.
- Monitor and Maintain: Inspect and log all traffic, internal and external, to update policies iteratively.
