Microsoft 365 Business Premium security features included with Microsoft Entra ID P1

Microsoft 365 Business Premium remains one of the strongest security bundles for small and midsize businesses in 2026. The important update is no longer that these features are “new,” but that identity, device, email, and app protections are now expected baseline controls for every Microsoft 365 environment.

What changed since the original announcement

The 2020 article referred to Azure Active Directory Premium P1. Microsoft has since renamed Azure AD to Microsoft Entra ID, and the current license name is Microsoft Entra ID P1.

For 2026 planning, the key licensing point is this: Microsoft 365 Business Premium includes Microsoft Entra ID P1 for eligible users, along with Microsoft Intune, Microsoft Defender for Business, and Microsoft Defender for Office 365 Plan 1. This makes Business Premium a practical security baseline for organizations with up to 300 users.

Do not assume every Microsoft 365 or Office 365 plan includes Entra ID P1. Microsoft 365 Business Basic and Business Standard do not include the same identity and device security bundle. Microsoft 365 E3 includes Entra ID P1, Microsoft 365 E5 includes more advanced identity security such as Entra ID P2 capabilities, and Office 365 plans should be reviewed carefully because they are primarily productivity plans rather than full security suites. Under CSP/NCE, confirm the exact subscription name and included services before designing your controls.

Security Defaults vs. Conditional Access

Every Microsoft 365 tenant should have strong authentication controls. Security Defaults can help newer or smaller tenants enforce basic MFA protections without additional configuration. However, organizations that need role-based policies, trusted locations, device compliance requirements, session controls, or exceptions for specific workloads typically move to Conditional Access.

Microsoft Entra ID P1 enables Conditional Access policies, which are central to a Zero Trust approach. Common policies include requiring MFA for administrators, blocking legacy authentication, requiring compliant or hybrid joined devices for sensitive apps, limiting access by location or sign-in risk where licensed, and controlling browser or mobile access to cloud apps.

Microsoft Entra application proxy for secure remote access

Microsoft Entra application proxy, previously called Azure AD Application Proxy, allows users to access certain on-premises web applications securely without publishing them directly to the internet or requiring a traditional VPN for every scenario.

It is useful for intranet portals, legacy web apps, and line-of-business systems that can be integrated with Entra ID. Users authenticate through Entra ID, and organizations can apply Conditional Access and MFA policies before access is granted.

Application proxy does not replace every VPN, Zero Trust Network Access, or private access architecture, but it is a valuable option for modernizing access to internal applications with less network exposure.

Microsoft Entra dynamic groups

Microsoft Entra dynamic groups help automate user and device membership based on attributes such as department, location, job title, device ownership, or operating system. Instead of manually maintaining security groups, IT teams can define rules and let Entra ID update membership automatically.

Dynamic groups are commonly used to assign Microsoft 365 licenses, deploy Intune policies, target Conditional Access policies, manage application access, and organize devices. As with all licensing features, make sure users benefiting from Entra ID P1 capabilities are properly licensed.

Passwordless authentication in 2026

Passwordless authentication is still one of the most effective ways to reduce password-related attacks. Microsoft supports several passwordless options, including Windows Hello for Business, passkeys and FIDO2 security keys, Microsoft Authenticator, and Temporary Access Pass for onboarding and recovery workflows.

A practical rollout often starts with administrators and high-risk users, then expands to the broader organization. Pair passwordless authentication with Conditional Access, device compliance through Intune, and strong recovery processes so users are not forced back into weak password habits.

Cloud app discovery and shadow IT visibility

The original article referred to Cloud App Discovery. In current Microsoft terminology, cloud discovery capabilities are associated with Microsoft Defender for Cloud Apps. Licensing can vary between discovery-only capabilities and the full Defender for Cloud Apps product, so review your subscription before assuming all cloud app security features are included.

For Microsoft 365 Business Premium customers, cloud app visibility can help identify unsanctioned SaaS usage, risky apps, and data leaving approved platforms. This is especially useful when combined with Microsoft Defender for Endpoint signals, Microsoft Defender for Office 365 email protection, and Conditional Access policies.

The broader Microsoft 365 Business Premium security bundle

The value of Microsoft 365 Business Premium is not limited to Entra ID P1. It also includes Microsoft Intune for device and app management, Microsoft Defender for Business for endpoint protection, Microsoft Defender for Office 365 Plan 1 for email and collaboration security, and selected Microsoft Purview capabilities for information protection and compliance.

Together, these services support a practical Zero Trust foundation: verify identities, protect devices, secure email, manage applications, reduce password risk, and enforce access policies based on user, device, location, and app context.

2026 implementation checklist

Start with the basics: enable MFA for all users, require phishing-resistant or passwordless methods for administrators where possible, block legacy authentication, configure self-service password reset, and create Conditional Access policies for administrator roles and sensitive apps.

Next, onboard Windows, macOS, iOS, and Android devices into Intune, define compliance policies, deploy Microsoft Defender for Business, and enable Defender for Office 365 protections for phishing, malicious attachments, and unsafe links.

Then improve maturity: use dynamic groups to automate policy assignment, review app access, evaluate cloud app discovery findings, document break-glass administrator accounts, test user recovery processes, and consider Entra ID P2 or additional Microsoft security services if you need advanced identity protection, risk-based policies, or deeper cloud app control.

Key takeaways

• Microsoft 365 Business Premium includes Microsoft Entra ID P1, but not every Microsoft 365 or Office 365 plan does.
• The current terminology is Microsoft Entra ID, Microsoft Entra ID P1, Microsoft Entra application proxy, and Microsoft Entra dynamic groups.
• Conditional Access, MFA, self-service password reset, passwordless authentication, and dynamic groups are core identity controls for 2026.
• Business Premium is more than an identity license: it also includes Intune, Defender for Business, and Defender for Office 365 Plan 1.
• Licensing should be verified under current CSP/NCE subscription names before deployment.

If you want to confirm whether your Microsoft 365 licenses include the right security capabilities, IT Partner can review your tenant, map your CSP/NCE subscriptions, and help deploy Microsoft 365 Business Premium, Microsoft Entra ID, Intune, and Defender controls without over-licensing.
