Microsoft Defender for Endpoint for Vulnerability Management and Reporting
Hi All, We’re currently using Rapid7 for vulnerability management and reporting, but we’re actively evaluating the possibility of moving to Microsoft Defender for Endpoint going forward. We’d like to better understand how to properly leverage Defender for Endpoint for vulnerability management and reporting. If this means using custom reports—such as building dashboards in Power BI—we’re definitely open to that approach. At a high level, we’re looking for guidance on best practices and the right direction to meet the following requirements: Ongoing vulnerability tracking and remediation Clearer reporting on vulnerability trends and areas needing improvement Breakdown of vulnerabilities by severity (Critical, High, Medium, Low), grouped by aging buckets (e.g., 30, 60, 90 days) Defender Secure Score reporting over time (30, 60, and 90-day views) Visibility into non-compliant devices in Intune, including devices in grace period and PCs that have checked in within the last 14 days Any recommendations, examples, or pointers to documentation or reporting approaches would be greatly appreciated. Thanks in advance, Dilan
MS Defender 101.25102 update error
I have been trying to update MS Defender for several days now and without luck. I am on a iMac M3 with macOS 26.1. I tried removing and reinstalling the app, but it seems that the uninstall script does not remove the app at all. Yes, I did restart the machine. Does anyone have a solution?
Correct firewall log names to be included in a Defender investigation package?
Hi - first time poster, I work in a SecOps team using Defender for Endpoint. I noticed that when we collect an investigation package from a device in Defender that the firewall logs aren't being found. The advice on Microsoft Learn articles seems to be contradictory as to what firewalls should be named as: https://learn.microsoft.com/en-us/defender-endpoint/respond-machine-alerts FirewallExecutionLog.txt and pfirewall.log The pfirewall.log file must exist in %windir%\system32\logfiles\firewall\pfirewall.log, so it's included in the investigation package. For more information on creating the firewall log file, see https://learn.microsoft.com/en-us/windows/security/operating-system-security/network-security/windows-firewall/configure-logging?tabs=intune. This section implies for the firewall log to be collected it has to be called "pfirewall.log" but on the linked page it is recommended to change the log file names: For each profile (Domain, Private, and Public) change the default log file name from %windir%\system32\logfiles\firewall\pfirewall.log to: %windir%\system32\logfiles\firewall\pfirewall_Domain.log %windir%\system32\logfiles\firewall\pfirewall_Private.log %windir%\system32\logfiles\firewall\pfirewall_Public.log We have tested the changed names and they are not found by the investigation package. Which one is recommended and is the logic used in the Defender investigation package correct?
