Many organizations purchase advanced Microsoft 365 security licenses like Microsoft 365 E5 because they know it includes Microsoft’s most powerful security capabilities.

But what we see in the real world is something very different.

In many environments, the sophisticated security features included in those licenses are never fully deployed.

When we review these environments, we often see things like:

  • Microsoft Intune partially deployed or not deployed at all
  • Company computers not fully enrolled in Azure Active Directory
  • Basic or incomplete conditional access policies
  • Insider Threat Management not configured
  • Microsoft Defender for Identity not deployed
  • Microsoft Purview compliance tools sitting unused

The platform is powerful, but the majority of the security capabilities remain untouched.

Why This Happens

This isn’t because internal IT managers lack intelligence or technical ability.

In fact, most internal IT managers are very capable.

The real issue is experience and risk.

Deploying integrated Microsoft 365 security systems requires hands-on experience across multiple environments. It takes repetition to build the confidence needed to integrate systems like:

  • Defender
  • Intune
  • Entra ID
  • Conditional Access
  • Compliance policies
  • Identity monitoring

But internal IT managers usually work on one network.

That network must remain stable, secure, and operational at all times. There is very little room for experimentation or learning through trial and error.

The reality is that most IT managers simply cannot afford the career risk of making their first large deployment on the only environment they manage.

The Experience Gap

This is one of the biggest differences between internal IT teams and organizations that specialize in Microsoft cloud systems.

Companies that design and deploy Microsoft 365 environments repeatedly gain the practical experience needed to confidently integrate the full security platform.

Internal IT teams rarely get the opportunity to deploy these systems over and over again.

And as a result, many companies end up owning powerful Microsoft security tools that are never fully implemented.
