Zero Trust Security for Small Businesses

What Is Zero Trust?

Zero trust means "never trust, always verify." Every user, device, and connection must be authenticated and authorised, regardless of location.

Zero Trust Principles

• Verify explicitly (MFA, device health checks)
• Use least privilege access
• Assume breach (segment networks, encrypt everything)

Implementing Zero Trust on a Budget

• MFA on all systems (low cost, high impact)
• Role-based access control
• Network segmentation (separate guest/corporate WiFi)
• Device health checks before granting access
• Regular access reviews
