Zero‑trust basics: a starter guide for growing organisations

The core ideas behind zero‑trust

• Verify explicitly: check identity, device health and context for every access request.
• Use least privilege: give people only what they need, only when they need it.
• Assume breach: design as if attackers are already on the inside and limit what they can do.

Where most organisations should start

You do not need a full redesign to get value. Start with identity and endpoints.

• Turn on MFA for all users, with stronger methods for admins and remote access.
• Use device compliance or similar to ensure only healthy, protected devices connect.
• Segment high‑risk or high‑value systems and apply tighter access controls.

How managed IT can help

A partner can help map your current environment, prioritise quick wins and run pilots in low‑risk groups before wider rollout.
