It is part of [Windows Defender Exploit Guard](windows-defender-exploit-guard.md). Exploit protection is supported beginning with Windows 10, version 1709 and Windows Server 2016, version 1803. >[!TIP] >You can visit the Windows Defender Testground website at [demo.wd.microsoft.com](https://demo.wd.microsoft.com?ocid=cx-wddocs-testground) to confirm the feature is working and see how it works. Exploit protection works best with [Windows Defender Advanced Threat Protection](../windows-defender-atp/windows-defender-advanced-threat-protection.md) - which gives you detailed reporting into exploit protection events and blocks as part of the usual [alert investigation scenarios](../windows-defender-atp/investigate-alerts-windows-defender-advanced-threat-protection.md). You can [enable exploit protection](enable-exploit-protection.md) on an individual machine, and then use [Group Policy](import-export-exploit-protection-emet-xml.md) to distribute the XML file to multiple devices at once. When a mitigation is encountered on the machine, a notification will be displayed from the Action Center. You can [customize the notification](customize-attack-surface-reduction.md#customize-the-notification) with your company details and contact information. You can also enable the rules individually to customize what techniques the feature monitors. You can also use [audit mode](evaluate-exploit-protection.md) to evaluate how exploit protection would impact your organization if it were enabled. Many of the features in the [Enhanced Mitigation Experience Toolkit (EMET)](https://technet.microsoft.com/security/jj653751) have been included in Exploit protection, and you can convert and import existing EMET configuration profiles into Exploit protection. See [Comparison between Enhanced Mitigation Experience Toolkit and Windows Defender Exploit Guard](emet-exploit-protection-exploit-guard.md) for more information on how Exploit protection supersedes EMET and what the benefits are when considering moving to exploit protection on Windows 10. >[!IMPORTANT] >If you are currently using EMET you should be aware that [EMET reached end of life on July 31, 2018](https://blogs.technet.microsoft.com/srd/2016/11/03/beyond-emet/). You should consider replacing EMET with exploit protection in Windows 10. You can [convert an existing EMET configuration file into exploit protection](import-export-exploit-protection-emet-xml.md#convert-an-emet-configuration-file-to-an-exploit-protection-configuration-file) to make the migration easier and keep your existing settings. >[!WARNING] >Some security mitigation technologies may have compatibility issues with some applications. You should test exploit protection in all target use scenarios by using [audit mode](audit-windows-defender-exploit-guard.md) before deploying the configuration across a production environment or the rest of your network. ## Review exploit protection events in Windows Event Viewer You can review the Windows event log to see events that are created when exploit protection blocks (or audits) an app: Provider/source | Event ID | Description -|:-:|- Security-Mitigations | 1 | ACG audit Security-Mitigations | 2 | ACG enforce Security-Mitigations | 3 | Do not allow child processes audit Security-Mitigations | 4 | Do not allow child processes block Security-Mitigations | 5 | Block low integrity images audit Security-Mitigations | 6 | Block low integrity images block Security-Mitigations | 7 | Block remote images audit Security-Mitigations | 8 | Block remote images block Security-Mitigations | 9 | Disable win32k system calls audit Security-Mitigations | 10 | Disable win32k system calls block Security-Mitigations | 11 | Code integrity guard audit Security-Mitigations | 12 | Code integrity guard block Security-Mitigations | 13 | EAF audit Security-Mitigations | 14 | EAF enforce Security-Mitigations | 15 | EAF+ audit Security-Mitigations | 16 | EAF+ enforce Security-Mitigations | 17 | IAF audit Security-Mitigations | 18 | IAF enforce Security-Mitigations | 19 | ROP StackPivot audit Security-Mitigations | 20 | ROP StackPivot enforce Security-Mitigations | 21 | ROP CallerCheck audit Security-Mitigations | 22 | ROP CallerCheck enforce Security-Mitigations | 23 | ROP SimExec audit Security-Mitigations | 24 | ROP SimExec enforce WER-Diagnostics | 5 | CFG Block Win32K | 260 | Untrusted Font ## Comparison between Enhanced Mitigation Experience Toolkit and Windows Defender Exploit Guard >[!IMPORTANT] >If you are currently using EMET, you should be aware that [EMET reached end of life on July 31, 2018](https://blogs.technet.microsoft.com/srd/2016/11/03/beyond-emet/).
