What Is Microsoft Intune? A Complete Guide for Business IT Leaders

Modern businesses no longer operate inside a traditional office perimeter. Employees work from home, travel between locations, access cloud applications from personal devices, and connect to corporate data from virtually anywhere. While this flexibility increases productivity, it also creates significant security and management challenges for IT teams.

The question is no longer whether employees will use multiple devices. The question is how organizations can maintain security, consistency, and control across every endpoint. That’s where Microsoft Intune comes in.

Microsoft Intune has become a critical component of modern endpoint management strategies. As organizations adopt hybrid work models and cloud-first architectures, Intune provides centralized control over devices, applications, and security policies without requiring traditional on-premises infrastructure.

For business leaders evaluating Microsoft security investments, understanding Intune is essential. It plays a major role in endpoint security, supports Zero Trust initiatives, integrates closely with Microsoft Defender, and delivers many of the management capabilities included in Microsoft 365 E5.

In this guide, we will explain what Microsoft Intune does, how it supports modern security frameworks, and why it has become a foundational platform for businesses managing today’s hybrid workforce.

What Is Microsoft Intune?

Microsoft Intune is Microsoft’s cloud-based endpoint management platform.

It allows IT teams to manage and secure company-owned and personal devices from a centralized administration portal. Intune supports a wide range of operating systems, including:

• Windows
• macOS
• iOS
• iPadOS
• Android

Unlike traditional device management solutions that rely heavily on on-premises infrastructure, Microsoft Intune uses cloud-based endpoint delivery to simplify deployment, administration, and policy enforcement.

Organizations can use Intune to:

• Configure devices remotely
• Deploy applications
• Enforce security settings
• Monitor compliance
• Protect corporate data
• Control device access

As businesses continue moving toward cloud-first environments, Microsoft Intune provides the flexibility and scalability required to manage modern device ecosystems. 

At All In Technology, we help organizations deploy, configure, and optimize Microsoft Intune to improve endpoint security, enforce device compliance policies, and simplify device management across hybrid workforces.

Our team ensures Intune integrates seamlessly with Microsoft 365, Microsoft Defender, and Zero Trust security initiatives, helping businesses maintain control, consistency, and security across every managed endpoint.

What Does Microsoft Intune Do?

At its core, Microsoft Intune helps organizations maintain control over devices regardless of where employees work.

Instead of manually configuring individual laptops, smartphones, or tablets, IT teams can create policies that automatically apply security and configuration settings across the organization.

Common Intune capabilities include:

Mobile Device Management (MDM)

Mobile device management for business allows administrators to control device settings, enforce security requirements, and monitor compliance.

IT teams can:

• Require device encryption
• Enforce password standards
• Restrict unauthorized applications
• Configure Wi-Fi and VPN settings
• Perform remote wipes

Mobile Application Management (MAM)

Not every device belongs to the company. Many organizations support bring-your-own-device (BYOD) environments where employees access company resources using personal smartphones and tablets.

Intune allows IT departments to protect corporate data without managing the entire device. This approach creates a balance between security and user privacy while supporting workforce flexibility.

Application Deployment

Intune simplifies software deployment by allowing administrators to push approved applications directly to managed devices. Rather than relying on manual installations, organizations can ensure employees receive the correct applications, updates, and security configurations automatically. The result is improved endpoint consistency across the entire organization.

How Microsoft Intune Supports Zero Trust Security

Traditional security models assumed that users and devices inside the network perimeter could be trusted. Modern cyber threats have made that assumption dangerous.

Organizations now embrace Zero Trust principles, which operate under a simple philosophy:

Never trust. Always verify.

Microsoft Intune plays a key role in Zero Trust alignment by continuously validating device health before granting access to corporate resources.

Rather than simply checking a username and password, organizations can evaluate:

• Device compliance status
• Operating system version
• Security configurations
• Risk levels
• User identity signals

This approach significantly reduces opportunities for attackers to exploit unmanaged or compromised devices. Organizations implementing a Zero Trust Security Framework often rely on Intune as a foundational technology for endpoint governance and access control.

Combined with Microsoft Entra ID and Conditional Access policies, Intune helps create a security architecture that continuously verifies trust rather than assuming it. 

At All In Technology, we help businesses implement and manage these integrated security controls, strengthening Zero Trust strategies while ensuring users can securely access business resources from any location or device.

Device Compliance Policies Strengthen Security

One of the most valuable Intune features is its ability to enforce device compliance policies. A compliant device meets an organization’s predefined security requirements.

For example, an organization may require devices to:

• Use disk encryption
• Run approved operating system versions
• Maintain antivirus protection
• Enable firewall settings
• Prevent jailbroken or rooted devices

If a device falls out of compliance, Intune can automatically restrict access to business applications and sensitive data. This capability allows organizations to enforce security standards consistently without requiring constant manual oversight. As cyber threats continue to target endpoint devices, automated compliance enforcement has become an essential security control.

For organizations following the recommendations outlined in our Microsoft 365 Security Checklist, device compliance policies represent one of the most effective ways to reduce endpoint risk.

Endpoint Consistency Across the Hybrid Workforce

One of the biggest challenges facing modern IT teams is maintaining consistency. Employees work from different locations, use different devices, and often require access to different applications.

Without centralized management, device configurations quickly become fragmented.

This inconsistency creates:

• Security gaps
• Compliance concerns
• Support challenges
• Increased operational costs

Microsoft Intune helps solve this problem by standardizing endpoint configurations. Whether an employee works in the office, at home, or on the road, Intune ensures devices receive the same security policies, application deployments, and configuration settings.

When a new employee joins the organization, IT can provision devices using automated deployment processes rather than manual setup procedures. This improves operational efficiency while creating a more predictable and secure user experience. For organizations scaling rapidly, endpoint consistency becomes increasingly important as device counts grow.

Microsoft Intune and Microsoft Defender: Better Together

Many businesses view endpoint management and endpoint security as separate functions. In reality, they work best when integrated.

Microsoft Intune integrates closely with Microsoft Defender for Endpoint to create a more comprehensive security ecosystem.

Defender provides advanced threat detection and response capabilities, while Intune helps enforce the device standards necessary to reduce risk in the first place.

Together, they enable organizations to:

• Identify compromised devices
• Assess device risk levels
• Enforce remediation requirements
• Restrict access for risky endpoints
• Improve incident response workflows

For example, if Microsoft Defender identifies suspicious activity on a device, Intune can automatically trigger access restrictions until the issue is resolved. This integration strengthens both security operations and endpoint governance.

Businesses looking to maximize their Microsoft security investments often discover that Intune and Defender provide significantly greater value when deployed together.

How Microsoft Intune Fits Inside Microsoft 365 E5

Microsoft Intune is available through several Microsoft licensing options, but it becomes particularly powerful when combined with Microsoft 365 E5.
