Short answer: Microsoft 365 security is layered. Security defaults are available to every tenant, Conditional Access requires Microsoft Entra ID P1 (included in some bundles such as Microsoft 365 Business Premium), and risk-based policies require Entra ID Protection, a P2-level capability. Alert policies exist in the Microsoft Defender portal, but the activities they can detect and the advanced alerts available depend on your subscription and add-ons. Secure Score helps prioritize recommended actions; it is not a breach-prevention guarantee or a complete audit of your attack surface.
The safest way to plan is to identify the exact licenses assigned to users and administrators, map each desired control to its current entitlement, then deploy identity protections, alerting, and monitoring in that order.

Which Microsoft 365 license do you need for security?
There is no single “Microsoft 365 security license.” Each control has its own prerequisite, and a bundle can include several Entra or Defender rights without including every advanced feature. Microsoft’s licensing pages change as products are repackaged, so check the current entitlement for the specific user, administrator, and workload in your tenant before buying or configuring anything.

| Capability | Minimum path identified by Microsoft | What it provides |
|---|---|---|
| Security defaults | Available to all customers | Preconfigured protection for common identity attacks, including baseline multifactor authentication and legacy-authentication defenses. |
| Conditional Access | Microsoft Entra ID P1; also included in Microsoft Entra Suite and Microsoft 365 Business Premium | Rules that require or block access based on user, device, application, location, risk, and other conditions. |
| Risk-based Conditional Access policies | Microsoft Entra ID Protection (P2-level capability) | Policies that react to detected user or sign-in risk. |
| Entra ID Protection dashboard | Dashboard access is available with Free, P1, or P2 licenses | Visibility into identity-risk signals and activities. |
| Comprehensive ID Protection recommendations and recommended-action links | P2 | The full recommendation set and guided remediation links. |
| Some advanced risk detections | Microsoft 365 E5 or Enterprise Mobility + Security E5 | Additional detection coverage identified in Microsoft’s current documentation. |
The important distinction is between seeing a dashboard and being licensed for every policy, recommendation, or detection behind it. A Free or P1 user may be able to open parts of ID Protection, while P2 is needed for the comprehensive recommendations and action links. Some detections require an E5-level bundle.
When security defaults are enough
Security defaults are the baseline option when you do not have P1 or P2 and need a fast, broadly protective configuration. They are designed to reduce common identity attacks with preconfigured settings rather than a large policy-design project. They are less flexible than Conditional Access, so organizations with device-compliance, location, application, or granular risk requirements generally need P1 or a bundle that includes it.
When to choose Conditional Access
Conditional Access is the control layer for organizations that need tailored access rules. Typical examples include requiring stronger authentication for administrators, blocking access from unmanaged devices, or applying different requirements to sensitive applications. P1 is the prerequisite cited by Microsoft. Business Premium includes access to Conditional Access features, but you should still verify the assigned license and the exact feature in the tenant’s admin center.
When risk-based policies justify P2
Risk-based policies use Entra ID Protection signals to respond to suspicious users or sign-ins. They can automate a requirement such as multifactor authentication or force remediation when risk crosses a threshold. These policies require the P2-level ID Protection capability. Buying P1 and then expecting risk-based policy controls is a common licensing mistake.

No. Microsoft 365 alerting is available across the service, but the alert categories, thresholds, and advanced functionality vary by Microsoft 365 or Office 365 plan and by add-on. Answer “it depends on the alert,” not “all alerts require E5” or “every alert is included.”
What alert policies can watch
Microsoft alert policies generate an alert when user or administrator activity matches the policy’s conditions. Documented examples include:
- Assigning administrator privileges in Exchange Online.
- Malware attacks and phishing campaigns.
- Unusually high levels of file deletion.
- Unusual external sharing activity.
A policy can define activity conditions and thresholds and can determine whether email notifications are sent. Built-in policies cover common events, while custom policies can address organization-specific activity where the tenant’s plan supports it.
Why the subscription matters
Microsoft’s current alert catalog includes Safe Links malicious-URL alerts that require E5/G5 or Defender for Office 365 Plan 2, while other entries are available on broader plans. The presence of the Defender portal does not mean every catalog item is enabled for your tenant. Open the individual alert description and confirm its plan requirement before designing a monitoring process around it.

In the Microsoft Defender portal, go to Email & collaboration > Policies & rules > Alert policy. From there, administrators can review existing policies, inspect conditions and thresholds, create supported custom policies, and configure notification recipients.
Use the least-privilege role that performs the task. Microsoft documents read-only and management permissions for alert work and recommends reserving Global Administrator for emergencies or cases where a narrower role cannot perform the operation. Depending on the tenant’s role model, Security Reader, Security Administrator, or a scoped Defender role may be sufficient.
Understand alert-tuning rules before relying on the portal
Defender includes built-in alert-tuning rules intended to reduce noise from common benign activity. Review those rules deliberately: a suppressed alert will not appear in the portal in the same way as an unsuppressed event. Microsoft notes that these tuning rules do not apply to custom detection rules or Custom Threat Intelligence. Keep a record of important suppressions so an investigator knows whether an apparent gap is intentional.
How to protect a Microsoft 365 tenant: a practical sequence
- Inventory the assigned licenses. In the Microsoft 365 and Entra admin centers, list the licenses assigned to ordinary users, privileged administrators, service accounts, and pilot accounts. Do not infer entitlement from the tenant’s top-level subscription name; map each feature to the user who needs it.
- Map controls to requirements. For every planned control, record whether it needs security defaults, P1, P2, an E5-level bundle, or a Defender add-on. Recheck the current Microsoft licensing reference because bundles and feature names evolve.
- Use Secure Score to choose an order. Treat recommendations as a prioritized starting list. Select actions that reduce meaningful exposure while considering usability, support capacity, and application compatibility.
- Choose one identity baseline. If the tenant lacks paid Conditional Access features, assess whether security defaults provide the required baseline. If you deploy Conditional Access, document how it replaces or complements security defaults. Microsoft cautions against layering duplicative risk policies on top of security defaults without understanding their interaction.
- Pilot identity policies. Create a non-administrator test user, exclude emergency access accounts according to your recovery plan, and test sign-in, registration, device, and application scenarios before broad deployment. Keep a documented rollback path.
- Review ID Protection. Open the Entra ID Protection dashboard, examine user and sign-in risk, and confirm which recommendations and detections are available under your license. Risk information can feed Conditional Access or a SIEM for further analysis.
- Configure alert policies. In Defender, verify that the activity categories you care about are available, set thresholds and email notifications, and assign narrowly scoped roles to operators.
- Review tuning and response ownership. Examine built-in tuning rules, identify suppressed categories, and assign an owner and response procedure for each high-value alert. An alert without a responder is only a log entry.
- Recheck after changes. Revisit licenses, policies, alerts, and score recommendations after subscription changes, mergers, new applications, or major authentication changes.
What Entra ID Protection does—and what it does not do
Entra ID Protection detects identity-based risks, reports them, and supports investigation and remediation. Its signals can be used directly in Conditional Access or forwarded to a SIEM. The dashboard can also aggregate signals from other Microsoft security products when Defender for Identity is configured.
Microsoft’s full deployment guidance calls for a working Entra tenant with P2 or a trial for the complete scenario. It also identifies some detections that require Microsoft 365 E5 or Enterprise Mobility + Security E5. A tenant can therefore have ID Protection visibility without having every detection or automated remediation option.
Deployment and permissions
Use a non-administrator test user for validation. Assign separate roles for reading ID Protection, managing its data, and editing Conditional Access policies where possible. This separation limits the damage from an over-privileged account and makes change ownership clearer.
Dashboard timing
Microsoft documents a 24-hour refresh frequency for the ID Protection “number of attacks blocked” metric. That is documented product behavior, not a service-level guarantee and not proof that no attacks occurred between refreshes. Investigations should use the underlying risk activities and sign-in records as well as summary cards.
What does Microsoft Secure Score actually tell you?
Secure Score measures progress against Microsoft’s recommended actions. A higher score means more recommended actions have been completed or an accepted alternate mitigation has been recognized. It is useful for prioritization and executive reporting, but it is not a percentage likelihood of avoiding a breach, a certification, or a complete inventory of every attack surface.

Recommendations can include Microsoft and supported third-party products, and some actions trade security benefit against user friction or operational cost. Review the rationale and impact before enabling a control globally.
| Secure Score recommendation | Published points | How to interpret it |
|---|---|---|
| Ensure all users can complete multifactor authentication for secure access | 9 points | A measure of completing that recommendation, not nine percentage points of total security. |
| Require multifactor authentication for administrative roles | 10 points | Prioritizes privileged identities, but does not replace a broader administrator protection plan. |
| Enable a policy to block legacy authentication when security defaults are enabled | 7 points | Recognizes a specific configuration; it is not a guarantee that every legacy path is eliminated. |
Use the score to create a ranked backlog, then validate each recommendation against your applications, users, recovery procedures, and licensing. A score increase is evidence that recommended actions were completed—not evidence that every attack path is closed.

Common mistakes and recovery steps
Assuming a bundle includes every security feature
Fix this by checking the feature-level entitlement for the affected user and workload. A bundle that includes P1 does not automatically grant P2 risk policies or every Defender alert.
Granting Global Administrator for routine alert work
Fix this by testing Security Reader, Security Administrator, or a narrower Defender role that has the required read or management permission. Keep emergency administrator accounts protected and monitored.
Turning on overlapping identity policies without testing
Fix this by documenting whether security defaults remain enabled, piloting with a non-administrator, and testing registration, trusted devices, external access, and recovery accounts before enforcing the policy.
Treating Secure Score as a security grade
Fix this by pairing each recommendation with an owner, a risk rationale, an exception record, and a validation test. Track unresolved attack surfaces that Secure Score does not measure.
Ignoring alert suppression
Fix this by reviewing tuning rules whenever an expected alert is absent and recording which benign patterns are intentionally suppressed. Check custom detections separately because the built-in tuning rules do not apply to them.
Administrator MFA and physical security keys
A FIDO2 security key can be an optional way to strengthen administrator authentication, particularly for highly privileged accounts. Microsoft’s licensing and Secure Score documentation do not identify a specific model or verify compatibility with an individual tenant. Before purchasing, confirm that the key is supported by your authentication methods, enrollment process, recovery design, and Conditional Access policies. A key protects the account using it; it does not provide tenant-wide protection by itself.
How often should you review Microsoft 365 security?
Review licensing and high-impact policies after every subscription or staffing change. Review alert policies and tuning at a defined operational cadence, and investigate unusual activity as it appears rather than waiting for a score refresh. Revisit Secure Score recommendations when Microsoft changes the catalog, because point values and recommended actions can change. Microsoft’s Defender for Office 365 usage-card documentation describes usage details from the previous 28 days; treat that window as a reporting view, not a complete historical record.
