Deep Dive into Preview Features in Microsoft Defender Console
Background for Discussion Microsoft Defender XDR (Extended Detection and Response) is evolving rapidly, offering enhanced security capabilities through preview features that can be enabled in the MDE console. These preview features are accessible via: Path: Settings > Microsoft Defender XDR > General > Preview features Under this section, users can opt into three distinct integrations: Microsoft Defender XDR + Microsoft Defender for Identity Microsoft Defender for Endpoint Microsoft Defender for Cloud Apps Each of these options unlocks advanced functionalities that improve threat detection, incident correlation, and response automation across identity, endpoint, and cloud environments. However, enabling these features is optional and may depend on organizational readiness or policy. This raises important questions about: What specific technical capabilities are introduced by each preview feature? Where exactly are these feature parameters are reflected in the MDE console? What happens if an organization chooses not to enable these preview features? Are there alternative ways to access similar functionalities through public preview or general availability?
Integrate Defender for Cloud Apps w/ Azure Firewall or VPN Gateway
Hello, Recently I have been tasked with securing our openAI implementation. I would like to marry the Defender for Cloud Apps with the sanctioning feature and the Blocking unsanctioned traffic like the Defender for Endpoint capability. To do this, I was only able to come up with: creating a windows 2019/2022 server, with RRAS, and two interfaces in Azure, one Public, and one private. Then I add Defender for Endpoint, Optimized to act as a traffic moderator, integrated the solution with Defender for cloud apps, with BLOCK integration enabled. I can then sanction each of the desired applications, closing my environment and only allowing sanctioned traffic to sanctioned locations. This solution seemed : difficult to create, not the best performer, and the solution didn't really take into account the ability of the router to differentiate what solution was originating the traffic, which would allow for selective profiles depending on the originating source. Are there any plans on having similar solutions available in the future from: VPN gateway (integration with Defender for Cloud Apps), or Azure Firewall -> with advanced profile. The Compliance interface with the sanctioning traffic feature seems very straight forward .
Newly Created DfE Device Groups not immediately usable
I created a device group via https://security.microsoft.com/securitysettings/endpoints/machine_groups to apply a custom Indicator URL block for a single device based on an exact device name match. I ensured that the device is matched with the group rule using the Preview Device feature. Immediately after creating the device group, I clicked on Apply Changes on the device group page but after an hour, the device group still shows 0 device members and is not yet visible when creating the custom TI URL rule. It's extremely frustrating when we need to respond quickly to threats but have to wait for back-end replication/scripts to run just for creating and using a Defender device group.MS Defender Azure Arc Logic App
What is the best procedure for configuring a Logic App for Microsoft Defender in an Azure Arc environment? We had a very unexpected experience during onboarding—after configuring the Logic App, we missed setting a cap, and within a week, it consumed over $18K USD. I believe there must be a way to fine-tune the configuration to optimize costs. From my perspective, no organization would adopt an environment with such high costs for Microsoft Defender Plan 2 without better cost control measures in place. Could you suggest best practices or optimizations to prevent such excessive consumption?
Weird updates "Security Threat Intelligence" on desktop
Hi guys, my name is Mo and I am new to the XRD community 🥰 I m observing anomalous device behavior. Upon login or wake-up, multiple virtual machines are active, some exhibiting headless screen reader functionality. This issue emerged following the installation of Microsoft security threat intelligence updates. Considering Windows Defender's machine learning and predictive maintenance capabilities, I question the deployment of these updates to my system. Is this update a standard Windows component? The associated URL is currently inaccessible. I acknowledge the potential of XR, CDN, and Hologres technologies (and other Azure/cloud-enabled features) to alter user experience. Could someone provide clarification regarding these iterative security updates? My usage is limited to cloud platforms and reputable open-source software; I do not utilize malicious websites. Thank you. #misclassification?
XDR Critical asset management - Custom classifications not picking up assets
Hi community, I tried creating a number of Custom classifications. For example, by creating a filter on Identity -> AD Roles, or Cloud resource -> Category -> virtual_machine. When previewing the filter during creation, it displays the desired results. The classifications are created without any errors. But when I go back after refreshing the page, the Custom classifications I just created contain "0" resources. Clicking any classification , on the Assets tab, they show zero members (assets). What did I do wrong? Best Regards, Andy
