Introducing Microsoft Defender for Business
We’re excited to introduce Microsoft Defender for Business, a new endpoint security solution that’s now generally available within Microsoft 365 Business Premium, and Standalone solution in preview. Microsoft Defender for Business is specially built to bring enterprise-grade endpoint security to businesses with up to 300 employees, while being easy-to-use and cost-effective.Azure Active Directory Premium P1 is coming to Microsoft 365 Business Premium
With Microsoft 365 Business Premium (previously Microsoft 365 Business), we’re on a journey to deliver a comprehensive productivity and security solution for businesses with less than 300 employees. It integrates your favorite Office apps and collaboration tools including Microsoft Teams with advanced security and device management capabilities. We're adding another key capability to the Microsoft 365 Business Premium subscription - full Azure Active Directory Premium P1 license.Microsoft 365 E5 Security is now available as an add-on to Microsoft 365 Business Premium
The threat landscape continues to evolve creating ongoing challenges for small and medium businesses (SMBs) that are faced with increased regulations and cyberinsurance requirements. Today, Microsoft 365 Business Premium delivers core security solutions to SMBs that help safeguard data, defend against cyberthreats, and manage access and devices. With the growing volume of attacks and increased sophistication of threats, there are SMBs that want enhanced cybersecurity protection for their business. We are pleased to announce that Business Premium customers are now able to purchase Microsoft 365 E5 Security as an add-on to further enhance their security. E5 Security brings new security value on top of Business Premium with Microsoft Entra ID Plan 2, Microsoft Defender for Identity, Microsoft Defender for Endpoint Plan 2, Microsoft Defender for Office 365 Plan 2, and Microsoft Defender for Cloud Apps. (ENHANCED) Identity and access controls Business Premium includes Microsoft Entra ID P1, which provides single sign-on, multi-factor authentication (MFA), and conditional access to help SMBs manage user identities and enable access to applications and resources from trusted users, devices, and locations. Microsoft Entra ID P2 offers advanced security and governance features including Microsoft Entra ID Protection and Microsoft Entra ID Governance. Microsoft Entra ID protection offers risk-based conditional access that helps block identity attacks in real time using behavioral analytics and signals from both user risk and sign-in risk. It also enables SMBs to detect, investigate, and remediate potential identity-based risks using sophisticated machine learning and anomaly detection capabilities. With detailed reports and alerts, your business is notified of suspicious user activities and sign-in attempts, including scenarios like a password-spray where attackers try to gain unauthorized access to company employee accounts by trying a small number of commonly used passwords across many different accounts. ID Governance capabilities are also included to help automate workflows and processes that give users access to resources. For example, IT admins historically manage the onboarding process manually and generate repetitive user access requests for Managers to review which is time consuming and inefficient. With ID Governance capabilities, pre-configured workflows facilitate the automation of employee onboarding, user access, and lifecycle management throughout their employment, streamlining the process and reducing onboarding time. (NEW) Extended Detection and Response (XDR) Microsoft Defender XDR delivers a unified and efficient approach to incident-level visibility across the attack lifecycle. Together XDR and exposure management (XSPM) consolidate multiple siloed security solutions to provide best-of-breed capabilities across identities, endpoints, apps, and email. (NEW) Identity threat detection and response (ITDR) Identities are one of the most common attack vectors making identity-specific threat detection and response a critical element to secure your business. Microsoft Defender for Identity includes dedicated sensors and connectors for common identity elements that offer visibility into your unique identity landscape and provide detailed posture recommendations, robust detections and response actions. These powerful detections are then automatically enriched and correlated with data from other domains across Defender XDR for true incident-level visibility. (ENHANCED) Device security Microsoft Defender for Business (MDB) already brings enterprise-grade device protection capabilities to Business Premium customers across Windows, MacOS, iOS, and Android devices. It includes vulnerability management, next-generation antivirus protection, AI-powered endpoint detection and response with automatic attack disruption, and automated investigation and remediation. With streaming APIs, customers and partners can build Managed Detection and Response (MDR) services with Defender for Business. For customers who need advanced hunting, Microsoft Defender for Endpoint P2 adds advanced hunting, and 6 months of data retention on the device, along with endpoint security for IoT devices. (ENHANCED) Email and Collaboration security Microsoft Defender for Office 365 P1 in Business Premium includes SafeLinks with time of click URL filtering, safe attachments with real-time attachment scanning in sandbox, and phishing and malware defense across email, Microsoft Teams, OneDrive and SharePoint. It also has AI-powered LLM-based threat protection with 99.995% attacker intent detection accuracy. With Defender for Office 365 P2, you gain access to cyber-attack simulation training, which provides SMBs with a safe and controlled environment to simulate real-world cyber-attacks, helping to train employees in recognizing phishing attempts. Additionally automated response capabilities and post-breach investigations help reduce the time and resources required to identify and remediate potential security breaches. Detailed reports are also available that capture information on employees’ URL clicks, internal and external email distribution, and more. (NEW) Software-as-a-service (SaaS) security Microsoft Defender for Cloud Apps is a comprehensive, AI-powered software-as-a-service (SaaS) security solution that enables IT teams to identify and manage shadow IT and ensure that only approved applications are used. It protects against sophisticated SaaS-based attacks, OAuth attacks, and risky interactions with GenAI apps by combing SaaS app discovery, security posture management, app-to-app protection, and integrated threat protection. IT teams can gain full visibility into their SaaS app landscape, understand the risks and set up controls to manage the apps. SaaS security posture management quickly identifies app misconfigurations and provides remediation actions to reduce the attack surface. E5 Security delivers added protection to meet the growing needs of SMBs in a package that is cost-effective. Purchasing E5 Security has 57% savings when compared to the cost of separately purchasing the individual products that are included. FAQ When will E5 Security be available for purchase? E5 Security is available for purchase as an add-on to Business Premium starting today, 3/6. How can I purchase E5 Security? You can purchase E5 Security as an add-on to Business Premium through Microsoft Security for SMBs website or through your Partner. Does Microsoft 365 Business Premium plus Microsoft 365 E5 Security allow mixed licensing for endpoint security solutions? Microsoft Defender for Business does not support mixed licensing so a tenant with Defender for Business (included in Microsoft 365 Business Premium) along with Defender for Endpoint Plan 2 (included in Microsoft 365 Security) will default to Defender for Business. For example, if you have 80 users licensed for Microsoft 365 Business Premium and you’ve added Microsoft 365 E5 Security for 30 of those users, the experience for all users will default to Defender for Business. If you would like to change that to the Defender for Endpoint Plan 2 experience, you should license all users for Defender for Endpoint Plan 2 (either through standalone or Microsoft 365 E5 Security) and then contact Microsoft Support to request the switch for your tenant. You can learn more here. What are the differences between Microsoft Defender for Business and Microsoft Defender for Endpoint P2? MDB includes many of the same features as MDE P2, including enterprise-grade device protection for Windows, MacOS, iOS, and Android devices, vulnerability management, next-generation antivirus protection, AI-powered endpoint detection and response with automatic attack disruption, and automated investigation and remediation. MDE P2 adds endpoint security for IoT devices, threat hunting, and 6 months of data retention on the device. A detailed comparison is available here. As a Partner, how do I build Managed Detection and Response (MDR) services with MDB? For partners or customers looking to build their own security operations center (SOC) with MDR, Defender for Business supports the streaming of device events (device file, registry, network, logon events and more) to Azure Event Hub, Azure Storage, and Microsoft Sentinel to support advanced hunting and attack detection. If you are using the streaming API for the first time, you can find step-by-step instructions in the Microsoft 365 Streaming API Guide on configuring the Microsoft 365 Streaming API to stream events to your Azure Event Hubs or to your Azure Storage Account.

Privacy is built in, so you can act early without breaking employee trust. Protect sensitive data wherever it goes Microsoft Purview Information Protection classifies and labels sensitive data, so the right protections follow the data wherever it goes. Think of it as a ‘security tag’ that stays attached to a document whether it’s stored in OneDrive, shared in Teams, or emailed outside the company. Policies can be set based on the ‘tag’ to prevent data oversharing, ensuring sensitive files are only accessible to the right people. Microsoft Purview Data Loss Prevention (DLP) works in the background to stop sensitive information, like credit card numbers or health data, from being accidentally shared with unauthorized people Microsoft Purview Message Encryption adds another layer by making sure email content stays private, even when sent outside the organization.

Together, these capabilities help SMBs operate with the same level of compliance and data protection as large enterprises but simplified for smaller teams and tighter budgets.
