Web content filtering and indicator aren't working on third party browser
Hi, we have just noticed that web content filtering and customized indicators are not working on third party browsers after upgraded defender for endpoint to 4.18.23050.3, the issue has happened to both Win10 and Win11 machines. Has anyone else got the same issue?30KViews5likes86CommentsSenseNdr.exe is slowly eating the memory
Hello, For a few days now, we have some Windows Server 2019 physical machines where almot all the memory is commited to sensendr.exe. If you terminate sensendr.exe, the process comes back after a few minutes. On one machine the problem came back after a little bit more than one day, on the others the problem has not come back (yet). All the machines are patches with the 2024-09 CU. Here is a view of the resource monitor : On another machine : Do you have any idea what could cause that and how to avoid it ? We can't find any error messages that could explain the problem. Thanks in advance for your answers Marc14KViews4likes53CommentsASR - Behavior Changes - Blocking under User Context Now?
Since July 7-27-2022 I have been seeing around 40 of 1800 machines in my work environment that are showing blocks under %userprofile% or usercontext for .dll blocks. This is new behavior and is recent. All of our machines have the same ASR rule applied, I checked on the machines via registry and their ASR rules are the same. ASR Rule/Example Path - that is having this issue Block executable content from email client and webmail GUID: be9ba2d9-53ea-4cdc-84e5-9b1eeee46550 Path: %userprofile%\AppData\Local\Assembly\tmp*variousfilesandpaths.dll Did this behavior change, is this a preview of a new feature or is this a bug? I am afraid this may spread to more machines. We have E5 License and an MS Ticket Open as well. Hoping someone hear knows something as well.Solved22KViews1like52CommentsWeb access performance issue when enabling network protection
Hi, this is another issue by following the upgrade to 4.18.23050.5 for fixing the Web content filtering issue. (The previous post can be found from Here . After upgraded to 4.18.23050.5, the web content filtering has backed to be working again, but now I've just noticed that another web access performance issue, the website loading time in the first time access from a 3rd party browsers are extremely longer than before.

We're trying to verify if we can block file uploads through the browser to all sites, unless these sites are part of an approved list or the user has an exception. We currently have a similar solution through a different vendor, but wanted to see if Defender for Endpoint is an alternative. So, if someone creates a new site, this site would not be allowed to be uploaded to unless the domain is added to an approved list. The alternative would be to block if the file has a specific label. Thanks,28KViews0likes30CommentsASR: Block abuse of exploited vulnerable signed drivers
Hey there, I am seeing a recommendation to apply the ASR Rule as listed above. It looks like a fairly new edition to the series of 16 ASR rules that can be configured. However, on closer inspection there doesn't yet appear to be an Intune/Endpoint Manager option to add this under the standard Endpoint Security / Attack Surface Rules section. There's an "Intune name" and a GUID but... I don't want to push this out via a MEM OMA-URI, it fractures where all the policies are kept and makes things messy. Can I ask when it is expected to have this baked into the main Attack Surface Reduction rules section? Seems a bit daft to make recommendations to implement the setting across all your endpoints when it's not as easy as all the other rules to actually implement? Thanks very much.

We have a couple of devices that are showing in MDATP which we would like to get rid of, however we are not in a position to run any scripts... One was registered in InTune by mistake and has been unregistered, and we cannot contact the owner anymore - and its still checking in. One device failed and was rebuilt with the same name but is now showing twice. Can we remove these?

Hi y'all, We are using Defender for Endpoint on our Intel Macs without a hitch (both corp & BYOD devices). Now we are trying to have BYOD Apple Silicon Macs deployed with Defender for Endpoint. This gives us a strange issue: The Defender for Endpoint icon in the menubar shows a warning: Action Needed. Protection works fine and everything looks okay. Only the Defender for Endpoint icon keeps showing a warning (Action Needed). When we click on the warning, just the normal Defender for Endpoint interface is shown, without any issues or actions. We can't find anything online and it's driving us crazy. To be clear: This works fine on our Intel Macs. Please some help! We are using Jamf Pro.Solved14KViews2likes26CommentsModern Unified MsSense.exe and CPU/disk usage on 2012 R2 after March updates
After updating servers this month, the 2012 R2 that have the ATP modern unified solution agent are seeing a massive increase in disk and cpu activity. Process monitor revealed that MsSense.exe is aggressively scanning the C:\Windows\System32\catroot directory which contains thousands of files. It seems to do this about every 10 minutes and it takes a while so it's pushing CPU to near 100 constantly. There was a MsSense.exe version update to 10.8047.22439.1056 with security update KB5005292. I am suspecting that is the cause and will be doing some comparison testing in attempts to confirm it. Anyone else seeing this behavior?Solved24KViews1like25CommentsMDE repeatable false positive "Multi-stage incident involving Privilege escalation..." How to fix?
Anyone else seeing this? It always has 57 alerts, too, and the Detection source is always 'Custom TI' and always at the same time in the morning. Doesn't matter if the machine is managed, AD joined, etc. More details - all show windows error manager process (the other week I saw similar, but triggered by windows activation check) Any ideas? I didn't set this tenant up, so I wonder if there is some weird setting somewhere that is causing these false positives. I don't see any entries under Endpoint settings, Rules, Indicators which is what I thought would have been causing this?3.8KViews0likes24CommentsOnboarding servers to MDE after September 2022
Paul_Huijbregts marysia_k HeikeRitter (Just mentioning a few of the employees active in the community in the hope that someone knows something) So I am rather confused how to handle MDE in servers now that stand-alone licensing for "MDE for servers" is being phased out, leaving just Defender for Servers. Servers in Azure are OK I suppose, since they are visible in Defender for Cloud to begin with, but this is not the case with servers in AWS, GCP, and On-premise. Q1: Azure Arc Do we now have to install the Azure Arc agent in servers outside of Azure, just to be able to activate the Defender for Servers plan in Defender for Cloud? Does this require Azure Arc licensing, or is this usage free like with AMA (AMA requires Arc outside of Azure, and can be used free when you just need to fulfill this prereq for AMA) Q2: Onboarding Can we still use GPO, MECM, local scripts etc for onboarding, or do we need to deploy via Defender for Cloud (by activating the Defender for Servers plan) Me and my colleagues are all very confused here, which also hinders our pre-sales as a MS partner, so any sort of information would be much appreciated. (We have been unable to get any real info from support or from our MS representatives it seems)8.4KViews4likes24CommentsMS Defender - Installation Error version 101.25072 on macOS
Dear experts, The latest version of MS Defender can't be installed. I'm getting an error message since release date (5th Aug). I have tested to restart the computer, tested with different networks, same issue 🙁Solved4.4KViews6likes22CommentsDevice Control Printer Protection - Blocks Print to PDF
When using the OMA URI policy ./Vendor/MSFT/Policy/Config/Printers/EnableDeviceControl to block printing via non-corporate printers. It is observed it blocks Print to PDF and Print to XPS function. Using the Application Guard Security Policy under ASR does not provide the required exclusion. Does anyone have any idea how to resolve. Thanks15KViews0likes22CommentsMDE apparently blocks MacOS Monterey 12.1 / 12.2 upgrades?
The last days we have encountered a situation where the upgrade to MacOS Monterey 12.1 or 12.2 fails. After several reboots the machine returns to the state before the upgrade started, with the addition of several applications crashing upon startup and needing reinstalls of these. This has happened to several machines, both Intel and ARM models when trying to upgrade from various MacOS versions such as 12.0.1 and 11.6.x. Several repeated attempts give the same result: It occurred that we might have a compatibility issue with Defender ATP (101.56.35) - and after removing this application completely and retrying the OS upgrade, this was completed without any issues. Defender ATP was then reinstalled and now works without issues. The same goes for other applications that were "corrupted" during the first tries. Among them are OneDrive and Teams. After a "delete and reinstall" they all now work fine. A less "Brutal" approach is also tried out (edit: which did not help) disabling various Defender modules, but this is rather time consuming since we do not know the result before the whole upgrade process is "complete". Anyone else seeing a similar pattern?12KViews2likes20CommentsDefender Web Content filtering for Chrome/Firefox
Hello all, We have recently configured Web Content Filtering. I am struggling with finding what is required to have the setup effect on Chrome and Firefox, exactly as it is seen via Edge. Has anyone had success with this? Any information would be greatly appreciated. thank you.6.9KViews0likes19CommentsServer 2012R2 and Server 2016 not reporting WDATP sensor data
We recently on-boarded a handful of Server 2012R2, 2016, and 2019 servers, as well as some Win10 laptops. All show "last seen" dates that are current. However, none of the 2012R2 or 2016 servers are reporting their exposure, inventory, etc. data at all to the WDATP Dashboard. Our 2019 servers and Win10 laptops are reporting correctly and fully it appears. We on-boarded the 2012R2/2016 servers via installation of the MMA agent with the Workspace ID/Key combo. They ARE seen in WDATP dashboard, just don't appear to be reporting any useful data like the 2019/Win10 machines are. We have ruled out OS and network firewalls as issues.Solved5.7KViews0likes18CommentsCreate and Manage Device Groups area is missing from my tenant
I tried following along with the documentation https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/machine-groups?view=o365-worldwide#create-a-device-group but I do not have a Permissions section (let alone Device Groups) under the Endpoint settings. Here is what the setting is supposed to look like And this is what my tenant looks like. I initially thought there was a problem with the documentation but after I submitted feedback they said there might be something wrong with the tenant. I just wanted to check with other users to see if they are seeing things properly or if others see the same as what I do. The doc reply said I should open a support ticket however this always redirects us to our reseller who for the lack of better words, are totally incompetent, and I'm unable to open tickets with MS directly. Would rather not waste my time. Regarding licenses, we have Business Premium. Am I just looking in the wrong spot or is something going on with our tenant?Solved5KViews0likes18Commentsproblems with MS Defender for Endpoint on iOS device
Hi. We recently deployed MS Defender for Endpoint on all our iOS devices through Intune. However, since then, people are complaining their internet browsing experience is not good. It's slow, some sites take forever to load (when they do), etc. When we manually disable the Defender VPN connection, it's working again. How can we fix this issue? Thanks.21KViews1like18Comments
