Zero Trust architecture for SMBs, without the enterprise price tag

Zero Trust gets marketed as an enterprise architecture with an enterprise budget. The core idea is simpler: never assume a user or device is trustworthy because of where it is on the network; verify identity, device health, and context on every access. For a company already paying for Microsoft 365 or Google Workspace, most of the capability is already licensed and just not turned on.

1. Identity is the perimeter

Centralize identity (Entra ID or Google), enforce phishing-resistant MFA, and make every application authenticate through it. If an app can’t do SSO, that’s a reason to replace the app.

2. Device health gates access

Enroll every device in MDM (Intune, Mosyle, Jamf). Require encryption, EDR, and current patches as a condition of accessing company data. A personal laptop with no EDR shouldn’t be able to open the finance share, no matter whose password it has.

3. Conditional Access does the deciding

Policies that evaluate user risk, sign-in risk, location, and device compliance on every request. Block legacy authentication outright. Step up to stronger auth for admin roles and sensitive apps.

4. Least privilege, just-in-time

Nobody holds standing admin. Elevation is requested, time-boxed, and logged. Service accounts get the same scrutiny as humans.

5. Replace the VPN with application access

Broad network VPNs grant a tunnel to everything. Zero Trust network access grants a session to one application after verifying identity and device. Users get a better experience; attackers lose lateral movement.

Where the budget actually goes

Not licenses — configuration, policy design, and the ongoing drift correction that keeps it enforced. That’s the part a platform automates. Helix continuously re-checks Conditional Access baselines and self-heals drift, which is how a 50-person company sustains a Zero Trust posture with no dedicated security staff.

Start with MFA and device compliance. The rest follows.
