Zero Trust, Explained for Decision-Makers

The old security model trusted anything inside the network perimeter. In a world of cloud, remote work and sophisticated threats, that assumption is dangerous. Zero Trust replaces it with a simple principle: never trust, always verify.

The core pillars

• Verify every user and device, every time — strong identity and MFA.
• Grant least-privilege access, scoped to what's needed.
• Assume breach — segment networks and monitor continuously.

Roll out in phases

Zero Trust is a journey, not a switch. Start with identity and MFA, then segment critical assets, then extend continuous monitoring across the estate. Each phase reduces risk on its own.
