Planning your move to Microsoft Defender portal for all Microsoft Sentinel customers
In November 2023, Microsoft announced our strategy to unify security operations by bringing the best of XDR and SIEM together. Our first step was bringing Microsoft Sentinel into the Microsoft Defender portal, giving teams a single, comprehensive view of incidents, reducing queue management, enriching threat intel, streamlining response and enabling SOC teams to take advantage of Gen AI in their day-to-day workflow. Since then, considerable progress has been made with thousands of customers using this new unified experience; to enhance the value customers gain when using Sentinel in the Defender portal, multi-tenancy and multi-workspace support was added to help customers with more sophisticated deployments. Our mission is to unify security operations by bringing all your data, workflows, and people together to unlock new capabilities and drive better security outcomes. As a strong example of this, last year we added extended posture management, delivering powerful posture insights to the SOC team. This integration helps build a closed-loop feedback system between your pre- and post-breach efforts. Exposure Management is just one example. By bringing everything together, we can take full advantage of AI and automation to shift from a reactive to predictive SOC that anticipates threats and proactively takes action to defend against them. Beyond Exposure Management, Microsoft has been constantly innovating in the Defender experience, adding not just SIEM but also Security Copilot. The Sentinel experience within the Defender portal is the focus of our innovation energy and where we will continue to add advanced Sentinel capabilities going forward. Onboarding to the new unified experience is easy and doesn’t require a typical migration. Just a few clicks and permissions. Customers can continue to use Sentinel in the Azure portal while it is available even after choosing to transition. Today, we’re announcing that we are moving to the next phase of the transition with a target to retire the Azure portal for Microsoft Sentinel by July 1, 2026. Customers not yet using the Defender portal should plan their transition accordingly. “Really amazing to see that coming, because cross querying with tables in one UI is really cool! Amazing, big step forward to the unified [Defender] portal.” Glueckkanja AG “The biggest benefit of a unified security operations solution (Microsoft Sentinel + Microsoft Defender XDR) has been the ability to combine data in Defender XDR with logs from third party security tools. Another advantage developed has been to eliminate the need to switch between Defender XDR and Microsoft Sentinel portals, now having a single pane of glass, which the team has been wanting for some years.” Robel Kidane, Group Information Security Manager, Renishaw PLC Delivering the SOC of the future Unifying threat protection, exposure management and security analytics capabilities in one pane of glass not only streamlines the user experience, but also enables Sentinel customers to realize security outcomes more efficiently: Analyst efficiency: A single portal reduces context switching, simplifies workflows, reduces training overhead, and improves team agility. Integrated insights: SOC-focused case management, threat intelligence, incident correlation, advanced hunting, exposure management, and a prioritized incident queue enriched with business and sensitivity context—enabling faster, more informed detection and response across all products. SOC optimization: Security controls that can be adjusted as threats and business priorities change to control costs and provide better coverage and utilization of data, thus maximizing ROI from the SIEM. Accelerated response: AI-driven detection and response which reduces mean time to respond (MTTR) by 30%, increases security response efficiency by 60%, and enables embedded Gen AI and agentic workflows. What’s next: Preparing for the retirement of the Sentinel Experience in the Azure Portal Microsoft is committed to supporting every single customer in making that transition over the next 12 months. Beginning July 1, 2026, Sentinel users will be automatically redirected to the Defender portal. After helping thousands of customers smoothly make the transition, we recommend that security teams begin planning their migration and change management now to ensure continuity and avoid disruption. While the technical process is very straightforward, we have found that early preparation allows time for workflow validation, training, and process alignment to take full advantage of the new capabilities and experience.

What is the Entity Analyzer? Assessing the risk of entities is a core task for SOC teams - whether triaging incidents, investigating threats, or automating response workflows. Traditionally, this has required building complex playbooks or custom logic to gather and analyze fragmented security data from multiple sources. With Entity Analyzer, this complexity starts to fade away. The tool leverages your organization’s security data in Sentinel to deliver comprehensive, reasoned risk assessments for any entity you encounter - starting with users and urls. By providing this unified, out-of-the-box solution for entity analysis, Entity Analyzer also enables the AI agents you build to make smarter decisions and automate more tasks - without the need to manually engineer risk evaluation logic for each entity type. And for those building SOAR workflows, Entity Analyzer is natively integrated with Logic Apps, making it easy to enrich incidents and automate verdicts within your playbooks. *Entity Analyzer is rolling out in Public Preview to Sentinel MCP server and within Logic Apps starting today. Learn more here. **Leave feedback on the Entity Analyzer here. Deep Dive: How the User Analyzer is already solving problems for security teams Problem: Drowning in identity alerts Security operations centers (SOCs) are inundated with identity-based threats and alert noise. Triaging these alerts requires analyzing numerous data sources across sign-in logs, cloud app events, identity info, behavior analytics, threat intel, and more, all in tandem with each other to reach a verdict - something very challenging to do without a human in the loop today. So, we introduced the User Analyzer, a specialized analyzer that unifies, correlates, and analyzes user activity across all these security data sources. Government of Nunavut: solving identity alert overload with User Analyzer Hear the below from Arshad Sheikh, Security Expert at Government of Nunavut, on how they're using the User Analyzer today: How it's making a difference "Before the User Analyzer, when we received identity alerts we had to check a large amount of data related to users’ activity (user agents, anomalies, IP reputation, etc.). We had to write queries, wait for them to run, and then manually reason over the results. We attempted to automate some of this, but maintaining and updating that retrieval, parsing, and reasoning automation was difficult and we didn’t have the resources to support it. With the User Analyzer, we now have a plug-and-play solution that represents a step toward the AI-driven automation of the future. It gathers all the context such as what the anomalies are and presents it to our analysts so they can make quick, confident decisions, eliminating the time previously spent manually gathering this data from portals." Solving a real problem "For example, every 24 hours we create a low severity incident of our users who successfully sign-in to our network non interactively from outside of our GEO fence. This type of activity is not high-enough fidelity to auto-disable, requiring us to manually analyze the flagged users each time. But with User Analyzer, this analysis is performed automatically. The User Analyzer has also significantly reduced the time required to determine whether identity-based incidents like these are false positives or true positives. Instead of spending around 20 minutes investigating each incident, our analysts can now reach a conclusion in about 5 minutes using the automatically generated summary." Looking ahead "Looking ahead, we see even more potential. In the future, the User Analyzer could be integrated directly with Microsoft Sentinel playbooks to take automated, definitive action such as blocking user or device access based on the analyzer’s results. This would further streamline our incident response and move us closer to fully automated security operations." Want similar benefits in your SOC? Get started with our Entity Analyzer Logic Apps template here. User Analyzer architecture: how does it work? Let’s take a look at how the User Analyzer works. The User Analyzer aggregates and correlates signals from multiple data sources to deliver a comprehensive analysis, enabling informed actions based on user activity. The diagram below gives an overview of this architecture: Step 1: Retrieve Data The analyzer starts by retrieving relevant data from the following sources: Sign-In Logs (Interactive & Non-Interactive): Tracks authentication and login activity. Security Alerts: Alerts from Microsoft Defender solutions. Behavior Analytics: Surfaces behavioral anomalies through advanced analytics. Cloud App Events: Captures activity from Microsoft Defender for Cloud Apps. Identity Information: Enriches user context with identity records. Microsoft Threat Intelligence: Enriches IP addresses with Microsoft Threat Intelligence. Steps 2: Correlate signals Signals are correlated using identifiers such as user IDs, IP addresses, and threat intelligence. Rather than treating each alert or behavior in isolation, the User Analyzer fuses signals to build a holistic risk profile. Step 3: AI-based reasoning In the User Analyzer, multiple AI-powered agents collaborate to evaluate the evidence and reach consensus. This architecture not only improves accuracy and reduces bias in verdicts, but also provides transparent, justifiable decisions. Leveraging AI within the User Analyzer introduces a new dimension of intelligence to threat detection. Instead of relying on static signatures or rigid regex rules, AI-based reasoning can uncover subtle anomalies that traditional detection methods and automation playbooks often miss. For example, an attacker might try to evade detection by slightly altering a user-agent string or by targeting and exfiltrating only a few files of specific types. While these changes could bypass conventional pattern matching, an AI-powered analyzer understands the semantic context and behavioral patterns behind these artifacts, allowing it to flag suspicious deviations even when the syntax looks benign. Step 4: Verdict & analysis Each user is given a verdict. The analyzer outputs any of the following verdicts based on the analysis: Compromised Suspicious activity found No evidence of compromise Based on the verdict, a corresponding recommendation is given. This helps teams make an informed decision whether action should be taken against the user. *AI-generated content from the User Analyzer may be incorrect - check it for accuracy. User Analyzer Example Output See the following example output from the user analyzer within an incident comment: *IP addresses have been redacted for this blog* &CK techniques, a list of malicious IP addresses the user signed in from (redacted for this blog), and a few suspicious user agents the user's activity originated from. typically have to query and analyze these themselves, feel more comfortable trusting its classification. The analyzer also gives recommendations to remediate the account compromise, and a list of data sources it used during analysis. Conclusion Entity Analyzer in Microsoft Sentinel MCP server represents a leap forward in alert triage & analysis. By correlating signals and harnessing AI-based reasoning, it empowers SOC teams to act on investigations with greater speed, precision, and confidence. *Leave feedback on the Entity Analyzer hereMicrosoft Security in Action: Zero Trust Deployment Essentials for Digital Security
The Zero Trust framework is widely regarded as a key security model and a commonly referenced standard in modern cybersecurity. Unlike legacy perimeter-based models, Zero Trust assumes that adversaries will sometimes get access to some assets in the organization, and you must build your security strategy, architecture, processes, and skills accordingly. Implementing this framework requires a deliberate approach to deployment, configuration, and integration of tools. What is Zero Trust? At its core, Zero Trust operates on three guiding principles: Assume Breach (Assume Compromise): Assume attackers can and will successfully attack anything (identity, network, device, app, infrastructure, etc.) and plan accordingly. Verify Explicitly: Protect assets against attacker control by explicitly validating that all trust and security decisions use all relevant available information and telemetry. Use Least Privileged Access: Limit access of a potentially compromised asset, typically with just-in-time and just-enough-access (JIT/JEA) and risk-based policies like adaptive access control. Implementing a Zero Trust architecture is essential for organizations to enhance security and mitigate risks. Microsoft's Zero Trust framework essentially focuses on six key technological pillars: Identity, Endpoints, Data, Applications, Infrastructure, & Networks. This blog provides a structured approach to deploying each pillar. 1. Identity: Secure Access Starts Here Ensure secure and authenticated access to resources by verifying and enforcing policies on all user and service identities. Here are some key deployment steps to get started: Implement Strong Authentication: Enforce Multi-Factor Authentication (MFA) for all users to add an extra layer of security. Adopt phishing-resistant methods, such as password less authentication with biometrics or hardware tokens, to reduce reliance on traditional passwords. Leverage Conditional Access Policies: Define policies that grant or deny access based on real-time risk assessments, user roles, and compliance requirements. Restrict access from non-compliant or unmanaged devices to protect sensitive resources. Monitor and Protect Identities: Use tools like Microsoft Entra ID Protection to detect and respond to identity-based threats. Regularly review and audit user access rights to ensure adherence to the principle of least privilege. Integrate threat signals from diverse security solutions to enhance detection and response capabilities. 2. Endpoints: Protect the Frontlines Endpoints are frequent attack targets. A robust endpoint strategy ensures secure, compliant devices across your ecosystem. Here are some key deployment steps to get started: Implement Device Enrollment: Deploy Microsoft Intune for comprehensive device management, including policy enforcement and compliance monitoring. Enable self-service registration for BYOD to maintain visibility. Enforce Device Compliance Policies: Set and enforce policies requiring devices to meet security standards, such as up-to-date antivirus software and OS patches. Block access from devices that do not comply with established security policies. Utilize and Integrate Endpoint Detection and Response (EDR): Deploy Microsoft Defender for Endpoint to detect, investigate, and respond to advanced threats on endpoints and integrate with Conditional Access. Enable automated remediation to quickly address identified issues. Apply Data Loss Prevention (DLP): Leverage DLP policies alongside Insider Risk Management (IRM) to restrict sensitive data movement, such as copying corporate data to external drives, and address potential insider threats with adaptive protection. 3. Data: Classify, Protect, and Govern Data security spans classification, access control, and lifecycle management. Here are some key deployment steps to get started: Classify and Label Data: Use Microsoft Purview Information Protection to discover and classify sensitive information based on predefined or custom policies. Apply sensitivity labels to data to dictate handling and protection requirements. Implement Data Loss Prevention (DLP): Configure DLP policies to prevent unauthorized sharing or transfer of sensitive data. Monitor and control data movement across endpoints, applications, and cloud services. Encrypt Data at Rest and in Transit: Ensure sensitive data is encrypted both when stored and during transmission. Use Microsoft Purview Information Protection for data security. 4. Applications: Manage and Secure Application Access Securing access to applications ensures that only authenticated and authorized users interact with enterprise resources. Here are some key deployment steps to get started: Implement Application Access Controls: Use Microsoft Entra ID to manage and secure access to applications, enforcing Conditional Access policies. Integrate SaaS and on-premises applications with Microsoft Entra ID for seamless authentication. Monitor Application Usage: Deploy Microsoft Defender for Cloud Apps to gain visibility into application usage and detect risky behaviors. Set up alerts for anomalous activities, such as unusual download patterns or access from unfamiliar locations. Ensure Application Compliance: Regularly assess applications for compliance with security policies and regulatory requirements. Implement measures such as Single Sign-On (SSO) and MFA for application access. 5. Infrastructure: Securing the Foundation It’s vital to protect the assets you have today providing business critical services your organization is creating each day. Cloud and on-premises infrastructure hosts crucial assets that are frequently targeted by attackers. Here are some key deployment steps to get started: Implement Security Baselines: Apply secure configurations to VMs, containers, and Azure services using Microsoft Defender for Cloud. Monitor and Protect Infrastructure: Deploy Microsoft Defender for Cloud to monitor infrastructure for vulnerabilities and threats. Segment workloads using Network Security Groups (NSGs). Enforce Least Privilege Access: Implement Just-In-Time (JIT) access and Privileged Identity Management (PIM). Just-in-time (JIT) mechanisms grant privileges on-demand when required. This technique helps by reducing the time exposure of privileges that are required for people, but are only rarely used. Regularly review access rights to align with current roles and responsibilities. 6. Networks: Safeguard Communication and Limit Lateral Movement Network segmentation and monitoring are critical to Zero Trust implementation. Here are some key deployment steps to get started: Implement Network Segmentation: Use Virtual Networks (VNets) and Network Security Groups (NSGs) to segment and control traffic flow. Secure Remote Access: Deploy Azure Virtual Network Gateway and Azure Bastion for secure remote access. Require device and user health verification for VPN access. Monitor Network Traffic: Use Microsoft Defender for Endpoint to analyze traffic and detect anomalies. Taking the First Step Toward Zero Trust Zero Trust isn’t just a security model—it’s a cultural shift. By implementing the six pillars comprehensively, organizations can potentially enhance their security posture while enabling seamless, secure access for users. Implementing Zero Trust can be complex and may require additional deployment approaches beyond those outlined here. Cybersecurity needs vary widely across organizations and deployment isn’t one-size-fits all, so these steps might not fully address your organization’s specific requirements. However, this guide is intended to provide a helpful starting point or checklist for planning your Zero Trust deployment.
