Visibility First: Why Every Device Should Be Managed Before It Accesses Company Data

AI is changing cybersecurity, but attackers still love simple gaps. One of the biggest is also one of the most basic: organisations often do not have full visibility over the devices accessing their Microsoft 365 environment.

You cannot protect what you cannot see.

That is why device onboarding into Microsoft Intune should be one of the first steps in any Microsoft 365 security improvement journey. Intune helps organisations manage devices, apply configuration policies, evaluate compliance, and understand whether endpoints meet the company's security requirements. Microsoft defines Intune compliance policies as rules and conditions used to evaluate whether managed devices meet the required configuration standard. Devices must satisfy those requirements to be considered compliant.

This matters because the device is often where risk becomes real. A user might have a strong password and MFA, but if they access company data from an unmanaged, outdated, unencrypted, or non-compliant device, the organisation is still exposed.

From visibility to enforcement

Once devices are onboarded and managed, organisations can move from "we hope devices are secure" to "we know which devices are secure enough."

That is where Conditional Access becomes powerful.

Microsoft Conditional Access can require that devices accessing company resources are marked as compliant with Intune policies before access is granted. Microsoft explicitly warns that this kind of policy depends on having Intune compliance policies in place first.

In practical terms, this means organisations can enforce a simple but powerful rule:

Only trusted users on trusted, managed, compliant devices should access company data.

That is a security basic, but it is a critical one.

What good looks like

A strong starting point includes:

• Onboarding corporate Windows, macOS, iOS, and Android devices into Intune.
• Defining minimum compliance requirements, such as encryption, antivirus, OS version, firewall, screen lock, and jailbreak/root detection.
• Using Conditional Access to restrict access to Microsoft 365 from unmanaged or non-compliant devices.
• Monitoring exceptions, stale devices, and users accessing data from unknown endpoints.

Microsoft's Zero Trust guidance also recommends requiring healthy and compliant devices with Intune, where Intune shares compliance status with Microsoft Entra ID and Conditional Access uses that status when deciding whether to allow access.

The Epiteera perspective

This is exactly where Epiteera helps.

Epiteera gives customers visibility into whether their device protection foundation is in place. Are devices onboarded? Are compliance policies configured? Are Conditional Access rules actually enforcing device trust? Are there gaps between what the organisation believes is protected and what is truly protected?

Before advanced security tooling can deliver value, the basics must be measurable.

And visibility is the first basic.
