What is Zero Trust security, and does a small business need it?

Zero Trust is a security approach summed up as "never trust, always verify." The old model assumed anything inside the office network was safe; Zero Trust assumes nothing is, and makes every user and device prove itself before granting access — every time.

Why the old "castle and moat" model fails

With staff working from home, on mobiles, and in the cloud, there is no longer a neat office "inside" to protect. Attackers who steal one password or compromise one laptop used to get free rein across the network. Zero Trust removes that implicit trust, so a single breach doesn't hand over everything.

It's an approach, not a product

You can't buy "Zero Trust" in a box — you build it from controls, most of which a small business can reach with tools it likely already has:

• Multi-factor authentication on every account — verify the user.
• Managed, compliant devices (via Intune) — verify the device is healthy.
• Conditional Access — allow or block sign-ins based on who, what device, and where.
• Least-privilege access — people can only reach what their role needs.

Does an SMB really need it?

You don't need an enterprise "Zero Trust programme," but the principles are genuinely valuable — and much of it overlaps with the Essential Eight and with what cyber insurers now expect.
