Zero Trust is a security model that moves away from "static, network-based perimeters" and instead focuses on protecting users, assets, and resources. It assumes that no implicit trust is granted based on network location—whether you are in the office or at home, every request is verified as if it originated from an uncontrolled network.
With the average cost of a global data breach now exceeding £3.2 million, Zero Trust is no longer a "nice-to-have." It is a practical strategy to reduce your "blast radius" and prevent a single compromised login from taking down your entire business.
Don't try to implement Zero Trust everywhere at once. Start by identifying your Protect Surface—the small group of critical systems that matter most.
Identity is your new perimeter. Access must be based on who is requesting it, not where they are. So, enforce MFA everywhere; remove "legacy" sign-in paths; separate admin accounts from daily user accounts.
Zero Trust asks: "Is this device safe to trust right now?" You should require patched OS, disk encryption, and active endpoint protection for all devices (including BYOD).
Users should only have the access they need to perform their current role—nothing more. Eliminate "Everyone" access groups; shift to role-based access; log all admin elevation requests.
Move verification to the resource level rather than the network level. This allows you to tighten sharing defaults; require "step-up" authentication for high-risk apps; assign a clear "owner" to every critical system.
Assume a breach will happen. Segment your environment so an attacker cannot move easily between systems. We can use micro-segmentation to isolate critical systems from general user traffic.
Verification is not a one-time event; it is continuous. Centralise alerts for sign-ins and critical apps; define a simple response plan for suspicious activity.
Zero Trust isn't a "box" you buy; it's a mix of people, processes, and technology. Start with one protect surface and commit to 30 days of measurable improvement.
