Most businesses on Microsoft 365 Business Premium are sitting on security capabilities they have never configured. Here is what they do and why they matter.

There is a pattern that comes up consistently when Via Wire works with a new business on their Microsoft 365 environment.

They are on Business Premium. They have MFA enabled. They feel reasonably well protected. And then we look at what is actually configured and find that two of the most impactful security tools included in their licence have never been touched.

Microsoft Intune’s automated patch management. Microsoft Defender’s AI-enabled threat detection. Both included. Both inactive. Both representing a meaningful and largely free security improvement that most businesses do not know they are missing.

This week TechPulse covers both of these in practical terms: what they do, why they matter, and how to know whether they are working in your environment.

 

 

 

The patch management gap

 

Unpatched software is one of the most consistent entry points for cyberattacks on small businesses. Every piece of software your business uses carries known vulnerabilities. Those vulnerabilities are fixed by updates. When those updates are not installed, those vulnerabilities stay open for attackers to exploit.

Most businesses know this in principle. The challenge is that keeping every device in a hybrid or remote team updated manually is genuinely difficult to do consistently. Someone dismisses the update prompt because they are in the middle of something. A laptop is rarely in the office when updates are pushed. A device gets missed entirely because nobody has a complete picture of what is in the estate.

The result is a patchwork of device states across the organisation. Some devices up to date. Some running software that has not been updated in months. And no central visibility over which is which.

 

 

 

How Microsoft Intune addresses this

 

Microsoft Intune, included with Microsoft 365 Business Premium, addresses the patch management problem through automation. Updates are pushed to every enrolled device automatically without requiring individual users to do anything. No prompts to dismiss. No devices missed. No vulnerabilities left open because someone clicked remind me later for the fourth time.

Beyond patch management, Intune provides the device compliance visibility that makes the rest of your security posture meaningful. Every enrolled device has a status: up to date or out of date, policy compliant or non-compliant, encrypted or unencrypted. That status is visible at a glance from a single dashboard and updated continuously rather than assessed on request.

For businesses that have never configured Intune, automated patch management is the most compelling reason to start. The security improvement is immediate, meaningful, and requires no ongoing management once it is set up.

 

 

 

The threat detection gap

 

Traditional security tools detect known threats. They work by comparing activity against a database of threats that have been seen, identified, and catalogued before. It is an effective model for known threats. It has always had a lag for new ones.

The speed and sophistication of modern attacks makes that lag significant. By the time a new attack technique is identified, catalogued, and pushed to signature databases, it may already have affected thousands of organisations.

 

 

 

How Microsoft Defender addresses this

 

Microsoft Defender uses AI-enabled threat detection that identifies unusual behaviour patterns rather than just known signatures. Rather than asking “have we seen this before?”, Defender asks “does this look right?” Anomalous activity, unusual access patterns, behaviour that does not match a user’s normal profile — all of it is flagged and a response is triggered automatically.

The practical result is a significantly faster response time between the moment a threat begins and the moment it is contained. For businesses where a breach could mean compromised client data, operational disruption, or regulatory exposure, that speed is not a technical detail. It is a material difference in outcome.

Microsoft Defender for Business is built into Microsoft 365 Business Premium. It provides endpoint detection and response, automated attack disruption, and vulnerability management across every device in the organisation from a single dashboard.

At Microsoft 365 E5, Defender for Endpoint extends this further into a comprehensive enterprise-grade endpoint security platform with advanced threat hunting, automated investigation, and full integration with Microsoft Intune so that a device flagged as compromised can be automatically quarantined without manual intervention.

 

 

 

 

Intune and Defender working together

 

The real value of having both Intune and Defender properly configured is not just the sum of what each does individually. It is how they work together.

Intune ensures every device is up to date and compliant before it is allowed to access company data. Defender monitors every device continuously for signs of compromise. If Defender flags a device as risky, Intune can automatically restrict its access to company systems without anyone having to manually review an alert and take action.

The result is a security posture that is proactive, automated, and continuous rather than reactive, manual, and periodic. For a small business without a dedicated security team, this matters enormously. The protection is always on, always current, and does not depend on someone remembering to check a dashboard.

 

 

 

Are these tools active in your environment?

 

The quickest way to check is to look at two places in your Microsoft 365 admin environment.

For Intune: go to endpoint.microsoft.com and check whether devices are enrolled and whether compliance policies are configured. If the device list is empty or compliance policies have never been set up, Intune is not working for your business yet.

For Defender: go to security.microsoft.com and check your Microsoft Secure Score alongside the Defender for Business dashboard. If Secure Score is low and the recommended actions list is long, there is meaningful protection available that has not been switched on.

Both of these checks take five minutes. What they surface is often more than five minutes’ worth of findings.
