Conditional Access is an Azure AD policy that evaluates the context of every login to Microsoft 365 — who is logging in, from what device, from what location, at what time of day — and applies access rules. For example: 'require MFA for any login from outside the corporate network' or 'block access from unmanaged devices.' For firms that primarily use Microsoft 365 for remote work (Outlook, Teams, SharePoint, OneDrive), Conditional Access provides security equivalent to a VPN without requiring staff to connect to a VPN before accessing their applications.
A GTA professional services firm had normalized hybrid work — staff splitting time between the office and home — but had never built the IT infrastructure to secure it properly. Personal devices were accessing corporate email and files, the legacy VPN was unreliable, and IT had no visibility into what was happening on devices outside the office. Group 4 Networks deployed Intune MDM, Conditional Access, and Azure AD to secure the hybrid environment without adding complexity for staff.
Yes. Zero Trust is an architectural principle, not a product — it means that no device or user is trusted by default, regardless of network location. The Microsoft 365 tooling that implements Zero Trust (Intune, Conditional Access, Azure AD) is included in the Business Premium license that many GTA businesses already pay for. G4NS configures these tools to implement a Zero Trust model appropriate for the size and risk profile of the business.
The firm had settled into permanent hybrid work following the pandemic without ever properly securing the model. Staff used a mix of company-issued and personal devices to access Microsoft 365 — Outlook, Teams, SharePoint — from home networks. The firm's IT administrator had no visibility into what devices were accessing corporate data from outside the office, whether those devices had antivirus, or whether they were up to date on OS patches.
No — not with Intune Mobile Application Management (MAM). MAM secures the work applications on a personal device (Outlook, Teams, SharePoint) without enrolling or managing the device itself. Staff install the Intune Company Portal app and accept a policy that applies only to work applications — their personal apps, photos, and data are not visible to or managed by the firm. Most staff find this acceptable once they understand the scope.
