When Your Business Needs a Microsoft 365 and Intune Health Check

In this blog post When Your Business Needs a Microsoft 365 and Intune Health Check we will explain the warning signs that your environment needs attention, what a useful review should cover, and when waiting creates unnecessary business risk.

For many organisations, Microsoft 365 simply appears to work. Email arrives, Teams meetings run, employees open files, and new laptops are connected. The problem is that a system can be operational without being secure, well managed, or cost-effective.

Microsoft 365 provides the business services your employees use every day, including email, collaboration, file storage, identity and security. Microsoft Intune, which manages and secures company computers, phones and tablets, controls whether those devices meet your security requirements before they access business data. Microsoft recommends combining Intune device compliance with Conditional Access, which applies rules to decide who can access company systems and under what conditions.

A health check looks at how these systems work together. It identifies gaps between what your policies say should happen and what is actually happening across user accounts, devices, applications and security alerts.

When should you arrange a health check?

There is no need to wait for a breach, failed audit or executive complaint. In fact, those are the most expensive times to discover that important settings were never enabled.

A Microsoft 365 Security and Intune Health Check is worth considering when one or more of the following situations applies.

1. Your Microsoft 365 environment has grown without a clear plan

Microsoft 365 environments rarely remain as originally designed. New employees, offices, applications, contractors and security products are added over time, often by different IT providers or internal administrators.

This can leave behind old administrator accounts, inconsistent security policies, unused licences and device groups that no longer reflect the business. Nobody deliberately created the problem. It developed gradually while the organisation focused on more urgent work.

If your setup has been running for several years without an independent review, a health check can uncover this accumulated risk. Our guide to the first steps in a Microsoft 365 security health check explains which areas deserve attention first.

2. You cannot produce a reliable list of company devices

Ask a simple question: how many computers and mobile devices can currently access your company data?

If the answer requires several spreadsheets, estimates from managers or a manual search through old records, Intune is probably not providing the control it should. This becomes especially risky when employees work remotely or use personal phones and computers.

A health check confirms whether devices are enrolled, encrypted, patched and protected by appropriate security policies. It also checks what happens when a device falls outside the rules. Intune can mark devices as non-compliant, notify users and provide compliance information to access policies, but only when these controls are configured and assigned correctly.

The business outcome is straightforward: fewer unmanaged devices, faster responses to lost equipment, and less chance of company information remaining on an insecure computer.

3. Multi-factor authentication is enabled but exceptions are unclear

Many organisations tell us that multi-factor authentication is enabled because most employees occasionally receive an approval prompt on their phone. That does not necessarily mean every account, application and access method is properly protected.

Old exclusions may still exist. Emergency administrator accounts may be poorly controlled. Contractors may have different rules from employees. A policy may also have been left in report-only mode, meaning it records what would happen but does not actually block risky access.

This is why a health check looks beyond whether a security feature appears to be switched on. It reviews who the policy covers, what it protects, which exceptions exist and whether the business can recover if legitimate users are accidentally locked out.

4. You are preparing for an audit, cyber insurance renewal or customer review

Security questionnaires increasingly ask for evidence, not verbal assurances. Customers, insurers and auditors may want proof that devices are patched, administrator access is restricted, multi-factor authentication is enforced and security issues are followed up.

This is particularly relevant for Australian organisations working towards the Essential Eight, the Australian government’s cybersecurity framework for reducing common cyber risks. Its controls include patching applications and operating systems, multi-factor authentication, restricting administrator privileges and regular backups.

A health check does not automatically make a business compliant. It gives decision-makers an honest view of what is working, where evidence is missing and which improvements should be prioritised.

5. You are paying for security features that may not be configured

Microsoft licensing can be difficult to follow. Businesses often upgrade licences to gain better security, device management or compliance features, but the new controls are not always deployed after the purchase.

The opposite also happens. Different products are bought to solve problems already covered by existing Microsoft licences. This creates duplicate costs, overlapping alerts and confusion about which system is responsible for protecting users.

A useful health check connects licensing to business requirements. It identifies paid features that are not being used, duplicated tools and genuine capability gaps. Microsoft Secure Score can help show improvement opportunities across identities, applications, data and devices, but it should be treated as a decision aid rather than a target that must reach 100 percent.

What should the health check examine?

A proper review should be broader than running an automated report. Reports are useful, but they do not understand your risk tolerance, workforce, contractual obligations or operational priorities.

At a minimum, the review should examine:

• User identities and administrator accounts to confirm access is limited, protected and regularly reviewed.
• Multi-factor authentication and Conditional Access to identify exclusions, weak rules and policies that are not being enforced.
• Intune enrolment and device compliance to confirm computers and mobile devices are visible, encrypted, updated and meeting company requirements.
• Security baselines, which are Microsoft-recommended groups of settings for protecting Windows devices, to find outdated versions, assignment gaps and conflicting policies.
• Personal device access to make sure business data cannot be freely copied into unapproved applications or personal storage. Intune app protection policies can protect company information even when a personal device is not fully managed by the organisation.
• Microsoft Defender integration, which detects threats on devices, to confirm that alerts and device risk information can influence access decisions.
• Licensing and feature use to identify unnecessary spending and controls the business already owns but has not deployed.
• Monitoring and ownership so there is a clear process for investigating non-compliant devices, security alerts and policy failures.

Our article on the first 10 things we check in a Microsoft 365 security review provides more detail on the initial warning signs.

A common real-world scenario

Consider a 180-person professional services company with employees working from home, client sites and two offices. The company has Microsoft 365 security licences and believes Intune is managing every laptop.

A review finds that newer Windows devices are enrolled correctly, but dozens of older computers are not receiving current policies. Several personal phones can access company email without app protection, and a legacy administrator account is excluded from important access rules.

The immediate answer is not to buy another security platform. It is to correct device enrolment, remove unnecessary exclusions, protect company data on personal phones and create a practical process for following up non-compliant devices.

The result is better visibility, reduced account and data risk, clearer compliance evidence and more value from licences the company is already paying for.

How often should the review happen?

For most businesses, an annual independent health check is a sensible minimum. Higher-risk organisations may need reviews every six months or after significant changes.

You should also arrange a review after changing IT providers, completing a merger, moving offices, introducing a bring-your-own-device policy, upgrading Microsoft licences, experiencing a security incident or receiving new compliance requirements from a customer.

The goal is not to generate a long technical report that nobody reads. A good health check should produce a prioritised action plan showing the business risk, recommended fix, likely effort, responsible owner and expected outcome.

Do not wait for a security gap to become a business problem

Microsoft 365 and Intune can provide strong protection, but buying the licences does not guarantee that the controls are correctly designed, deployed or monitored. Small configuration gaps can remain invisible until an employee loses a device, an account is compromised or an auditor asks for evidence.
