How Secure Is Your
Intune Environment?

Microsoft Intune Security & Consulting Services

Microsoft Intune is the most powerful device management platform in the enterprise — and now one of the most targeted. Attackers have learned that compromising a single Intune admin account can wipe thousands of devices in minutes, deploy malicious configurations across entire fleets, or silently exfiltrate data through trusted management channels. No malware required. No endpoint detection catches it. The commands come from a platform your devices are built to trust.

The problem isn't Intune itself — it's how it's configured. Most organizations deploy Intune to manage devices and push apps, then never harden the management plane. Admin accounts sit with permanent Global Admin privileges, protected by phishable MFA. Bulk destructive actions require no second approval. Audit logs go unmonitored. RBAC roles are never scoped. The result is an environment where the tool designed to protect your devices can be turned into the weapon that destroys them.

This page covers everything organizations need to know about securing, optimizing, and getting expert help with Microsoft Intune — from what it does and what licenses you need, to the critical hardening gaps most teams miss and how professional Intune consulting closes them.

What Is Microsoft Intune?

Microsoft Intune is a cloud-based endpoint management platform that gives IT teams centralized control over how devices access corporate resources. It combines Mobile Device Management (MDM) and Mobile Application Management (MAM) into a single console, covering Windows, macOS, iOS, Android, and Linux devices. Intune is part of the Microsoft Endpoint Manager ecosystem and integrates deeply with Entra ID (Azure AD), Conditional Access, Microsoft Defender for Endpoint, and the broader Microsoft 365 security stack.

At its core, Intune lets organizations enforce compliance policies (require encryption, OS versions, PIN/password, active threat protection), deploy and manage applications (push apps, configure settings, remove apps remotely), protect corporate data on personal devices through App Protection Policies without requiring full device enrollment, issue remote actions including lock, wipe, retire, and password reset, and deploy security baselines and configuration profiles across the device fleet.

The MDM Threat: When Your Management Tool Becomes the Weapon

The most dangerous evolution in enterprise attacks isn't new malware — it's the weaponization of trusted management platforms. Attackers have realized that MDM and UEM platforms like Intune have more power over your devices than any piece of malware ever could. A compromised Intune admin can issue a remote wipe command to every managed device in the organization simultaneously, deploy malicious configuration profiles that disable security controls fleet-wide, push rogue applications to every endpoint without triggering EDR alerts, modify compliance policies to mark compromised devices as "compliant," and extract device inventory, user data, and configuration details for reconnaissance.

These are "living off the land" attacks — the attacker uses your own trusted tools, so endpoint detection systems see legitimate management commands from a legitimate management platform. There's nothing to flag. The commands are indistinguishable from normal IT operations unless you have monitoring, alerting, and approval controls in place.

This is not theoretical. Real-world MDM wiper attacks have wiped hundreds of thousands of devices across dozens of countries, forcing organizations to urgently disconnect from their own management platforms mid-breach. The attack pattern is straightforward: compromise admin credentials (often through phishing or token theft), access the Intune admin console, and issue destructive commands at scale.

Intune Hardening Checklist: The Controls Most Organizations Miss

Based on real-world assessments and incident analysis, these are the critical Intune hardening controls that most organizations haven't implemented — even organizations that consider themselves mature Intune environments.

10 Intune Hardening Tips You Can Implement Today

You don't need a consultant to start hardening your Intune environment. Here are 10 actionable steps your team can take right now, ordered from highest-impact to lowest-effort. Each one directly addresses real-world attack vectors and misconfigurations we see in production environments.

1. Enable Multi-Admin Approval for Device Wipe Actions

What to do: In the Intune admin center, go to Tenant administration → Multi-Admin Approval → Access protection policies. Create a policy that requires a second administrator to approve bulk device actions including wipe, retire, and delete. Assign it to the roles that have access to these destructive actions.

Why this is #1: This is the single control that would have slowed or stopped the most high-profile MDM wiper attacks. A compromised admin account can wipe thousands of devices in minutes — unless a second admin has to approve the action first. This takes 10 minutes to configure and is the highest-impact hardening step you can take today.

2. Require Phishing-Resistant MFA for All Intune Admin Roles

What to do: Create a Conditional Access policy that targets all users in Intune admin roles (Intune Administrator, Endpoint Security Manager, etc.) and requires phishing-resistant authentication strength — either FIDO2 security keys or certificate-based authentication. In Entra ID, go to Protection → Authentication methods → Authentication strengths to define the requirement, then reference it in your Conditional Access grant controls.

Why: Standard MFA (push notifications, SMS codes) can be bypassed through adversary-in-the-middle (AiTM) proxy attacks and MFA fatigue. FIDO2 keys are bound to the legitimate site domain and cannot be phished. If your admin accounts are the keys to your entire device fleet, protect them with the strongest lock available.

3. Scope Intune Admin Roles with RBAC

What to do: In the Intune admin center, go to Tenant administration → Roles. Review all role assignments. Replace Global Admin and broad Intune Administrator assignments with scoped built-in roles: use Help Desk Operator for tier-1 support (no wipe access), Application Manager for app deployment, and reserve Intune Administrator for senior engineers only. Use scope tags to limit roles to specific device groups.

Why: If your helpdesk technician's account gets compromised, the attacker should be able to reset a password — not wipe every device in the organization. RBAC limits the blast radius of any compromised account to only the permissions that role actually needs.

4. Deploy Microsoft Security Baselines

What to do: In the Intune admin center, go to Endpoint security → Security baselines. Create profiles for the Windows Security Baseline, Microsoft Defender for Endpoint Baseline, and Microsoft Edge Baseline. Start with the Microsoft defaults — they represent hundreds of hours of security engineering. Assign to a test group first, validate for 1-2 weeks, then deploy broadly.

Why: These baselines configure dozens of hardening settings that most teams miss when building custom profiles from scratch — things like blocking legacy authentication at the device level, enforcing BitLocker, disabling SMBv1, configuring Windows Defender ASR rules, and hardening the browser. They're free, tested, and included in every Intune license.

5. Connect Compliance Policies to Conditional Access

What to do: First, verify your Intune compliance policies exist (encryption required, minimum OS version, no jailbreak, active threat protection). Then in Entra ID, create a Conditional Access policy targeting All users → All cloud apps → Grant: Require device to be marked as compliant. Start in report-only mode for 1-2 weeks to see what would be blocked, then switch to enforce.

Why: This is the most common gap we see — compliance policies exist in Intune but nothing happens when a device fails them. Without the Conditional Access connection, compliance is just a report nobody reads. With it, a non-compliant device gets blocked from corporate resources until the issue is fixed. That's the difference between a policy and a control.

6. Set Up Intune Audit Log Alerting

What to do: In the Intune admin center, go to Tenant administration → Audit logs and verify logging is active. Then stream these logs to Microsoft Sentinel or your SIEM via the Entra ID diagnostic settings (Entra ID → Monitoring → Diagnostic settings → Add → Send to Log Analytics workspace). Create alert rules for: bulk device wipe/retire actions exceeding 5 devices in 10 minutes, Intune role assignment changes, compliance policy modifications, and admin sign-ins from unfamiliar locations or outside business hours.

Why: Intune logs every admin action — but nobody monitors them until after a breach. Real-time alerting on destructive or anomalous actions is the difference between catching an attacker in the first 5 minutes versus discovering the damage the next morning. If you don't have a SIEM, at minimum set up email alerts through Azure Monitor.

7. Switch BYOD from MDM to MAM-Only

What to do: For personal devices, unenroll from full MDM and deploy App Protection Policies (MAM) instead. In the Intune admin center, go to Apps → App protection policies. Create policies for iOS and Android that require an app-level PIN, encrypt app data, block copy/paste from corporate apps to personal apps, block backup to personal cloud storage, and enable selective wipe (corporate data only). Then update your enrollment restrictions to block personal device MDM enrollment.

Why: Full MDM enrollment on personal devices gives your organization remote wipe capability over the employee's personal photos, messages, and apps. That's a legal liability, a trust issue, and — as MDM wiper attacks have shown — a risk amplifier. MAM-only protects corporate data at the app level without touching anything personal. Users keep control of their device; you keep control of your data.

8. Enable PIM for Intune Admin Roles

What to do: In Entra ID, go to Identity governance → Privileged Identity Management → Entra ID roles. Find the Intune Administrator role, click Settings, and configure it as "eligible" instead of "active." Set maximum activation duration to 4-8 hours. Require MFA and justification on activation. Repeat for Endpoint Security Manager and any custom Intune RBAC roles that include destructive permissions.

Why: PIM means Intune admin privileges only exist when actively needed and automatically expire. At 3 AM when the attacker tries to use compromised admin credentials, the account has zero Intune permissions — the attacker would need to activate the role first, which triggers MFA, requires justification, and generates an alert. This requires Entra ID P2 (included in M365 E5).

9. Export and Back Up Your Intune Configuration

What to do: Use Microsoft Graph API or the open-source Intune PowerShell samples to export all configuration profiles, compliance policies, app assignments, security baselines, and enrollment restrictions to JSON. Store these exports in a separate, secured location (not in the same tenant). Automate this export weekly using an Azure Automation runbook or a scheduled task.

Why: Intune has no native backup, no rollback, no version history. If an attacker deletes your compliance policies, modifies your security baselines, or wipes your configuration profiles — there is no undo button. Without offline backups, your only recovery option is rebuilding everything from memory and documentation (which probably doesn't exist). A weekly automated export takes 30 minutes to set up and could save you weeks of recovery time.

10. Add MDM Compromise to Your Incident Response Plan

What to do: Add a dedicated playbook to your IR plan covering this scenario: "Attacker has compromised an Intune admin account and is issuing destructive commands." The playbook should include immediate actions (revoke all active admin sessions via Entra ID, disable compromised account, block admin portal access via Conditional Access emergency policy), containment steps (isolate Intune service principal, audit all device actions in the past 24 hours, identify scope of impact), and recovery steps (restore configurations from backup, re-enroll wiped devices, rotate all admin credentials). Tabletop this scenario at least once a year.

Why: When your management platform becomes the attack weapon, your standard IR playbook doesn't apply. The response to "attacker deployed ransomware" is fundamentally different from "attacker used our own MDM to wipe every device." Teams that haven't rehearsed this scenario waste critical hours figuring out what to do while the attacker continues issuing commands. The organizations that survive MDM compromise are the ones that practiced for it.

These 10 steps represent the highest-impact hardening actions you can take without outside help. If you implement all of them, you'll be ahead of 90% of Intune environments we assess. For organizations that want a comprehensive evaluation, professional remediation, or help implementing these controls at scale, that's where consulting comes in.

Why Organizations Need Intune Consulting

Intune is included in licenses most organizations already pay for — but "included" doesn't mean "configured." The gap between deploying Intune and hardening Intune is where breaches happen. Here's what a specialized Intune consulting engagement delivers:

Intune Security Assessment & Hardening — A comprehensive audit of your Intune configuration against CIS Benchmarks, Microsoft security baselines, and real-world attack patterns. We evaluate admin access controls, RBAC scoping, compliance policy effectiveness, Conditional Access integration, audit log monitoring, and MDM abuse protections. You get a prioritized remediation plan with step-by-step implementation guidance.

Intune Deployment & Migration — Whether you're migrating from Group Policy, SCCM/ConfigMgr, or another MDM platform (Jamf, Workspace ONE, MobileIron), we design and execute the Intune deployment from enrollment strategy through security baseline deployment. This includes Autopilot configuration for zero-touch provisioning, compliance policy creation, application packaging and deployment, and Conditional Access integration.

BYOD & App Protection Strategy — Designing the right balance between security and user experience for personal devices. We implement MAM-only policies that protect corporate data without requiring full device enrollment, configure app-level PIN and encryption, and prevent data leakage from corporate apps to personal apps and cloud storage.

Compliance & Regulatory Alignment — Mapping Intune compliance policies to regulatory frameworks including HIPAA, PCI-DSS, CMMC, NIST 800-171, and SOX. We configure audit logging, data protection policies, and device compliance requirements that satisfy auditors and demonstrate due diligence.

MDM Threat Protection — Implementing the specific controls that prevent your Intune environment from being weaponized: phishing-resistant MFA for admins, Multi-Admin Approval for destructive actions, RBAC role scoping, audit log alerting for bulk operations, and incident response playbooks for MDM compromise scenarios.

Ongoing Management & Optimization — Quarterly policy reviews, security baseline updates when Microsoft releases new versions, compliance policy tuning to reduce false positives, and continuous monitoring of Intune audit logs for anomalous admin activity.

7 Most Common Intune Mistakes We See in Assessments

After auditing Intune environments across banking, healthcare, manufacturing, and professional services, these are the mistakes we find in nearly every engagement:

1. Compliance policies exist but aren't enforced. Organizations create compliance policies that define requirements (encryption, OS version, PIN) but never create the Conditional Access policy that blocks non-compliant devices. The result: devices are flagged as non-compliant in a report nobody reads, but users access everything without restriction.

2. Every IT person has Global Admin. During initial deployment, broad admin rights were granted to "get things working." Months or years later, 8-12 people have Global Admin — each one a potential entry point for a fleet-wide wipe attack. Scoped RBAC roles and PIM were never implemented.

3. Security baselines were never deployed. Teams build custom configuration profiles from scratch — missing dozens of hardening settings that Microsoft's tested baselines cover. The Windows Security Baseline, Defender Baseline, and Edge Baseline are available in Intune at no additional cost and represent hundreds of hours of Microsoft security engineering.

4. BYOD devices are fully enrolled in MDM. Personal devices are enrolled with full device management, giving the organization remote wipe capability over employees' personal photos, apps, and data. This creates legal liability, trust issues, and employee resistance. App Protection Policies (MAM-only) protect corporate data without touching personal data — but most teams don't know this option exists.

5. Intune audit logs aren't monitored. Audit logs capture every admin action — policy changes, device wipes, role assignments, enrollment modifications — but nobody looks at them until after an incident. By then, the damage is done. Real-time alerting on destructive actions and role changes is essential but almost never configured.

6. No backup of Intune configuration. Intune has no native backup or rollback. If a policy is deleted or misconfigured — whether by an attacker or an admin mistake — there's no "undo" button. Organizations that don't export their configurations via Graph API have no recovery path other than rebuilding from memory.

7. Policies haven't been reviewed since deployment. The business grows, new apps appear, hardware changes, new compliance requirements emerge — but Intune policies stay frozen from the initial deployment. Quarterly policy audits are essential to catch drift, remove obsolete rules, and align with current security baselines.

What is Microsoft Intune?

Microsoft Intune is a cloud-based endpoint management platform that provides Mobile Device Management (MDM) and Mobile Application Management (MAM) for Windows, macOS, iOS, Android, and Linux devices. It integrates with Entra ID and Conditional Access to enforce Zero Trust access policies.

Is Intune included in my Microsoft 365 license?

Intune is included in Microsoft 365 Business Premium, Microsoft 365 E3/E5/E7, Microsoft 365 F3, and Enterprise Mobility + Security E3/E5. It is not included in Business Basic, Business Standard, Office 365 E1/E3, or Microsoft 365 F1.

Can Intune be used as a weapon against my organization?

Yes. If an attacker compromises an Intune admin account, they can issue remote wipe commands, deploy malicious configurations, or disable security policies across your entire device fleet. These are legitimate management commands that endpoint detection systems won't flag. Multi-Admin Approval, phishing-resistant MFA, and RBAC scoping are essential mitigations.

What is the difference between MDM and MAM in Intune?

MDM (Mobile Device Management) enrolls the entire device into management, giving IT full control including remote wipe. MAM (Mobile Application Management) protects corporate data at the app level without enrolling the device — ideal for BYOD scenarios where you need to protect company data without controlling the employee's personal device.

What are Intune security baselines?

Security baselines are pre-configured groups of Windows settings recommended by Microsoft's security team. They cover hundreds of hardening settings for Windows, Microsoft Defender, Microsoft Edge, and Office applications. Deploying baselines through Intune is the fastest way to establish a hardened device configuration across your fleet.

How long does an Intune deployment take?

A basic Intune deployment (enrollment, compliance policies, app deployment) for a mid-sized organization typically takes 4-8 weeks. Full hardening — including security baselines, Conditional Access integration, BYOD policies, audit log monitoring, and admin access controls — adds another 2-4 weeks. Ongoing optimization is continuous.

What is Multi-Admin Approval in Intune?

Multi-Admin Approval is an Intune access protection policy that requires a second administrator to approve certain actions before they execute. This prevents a single compromised admin account from performing destructive operations like bulk device wipe, retire, or delete.

Does Intune have backup and rollback?

No. Intune does not offer native backup or rollback for configuration policies. If a policy is deleted or misconfigured, there is no undo button. Organizations should export configurations regularly using Microsoft Graph API and store backups offline or in a separate tenant.

What certifications should an Intune consultant have?

Look for MS-102 (Microsoft 365 Administrator), SC-300 (Identity and Access Administrator), SC-200 (Security Operations Analyst), and AZ-500 (Azure Security Engineer). These certifications demonstrate hands-on expertise with Intune, Entra ID, Conditional Access, and the broader M365 security stack.
