[Exploit protection](exploit-protection.md) helps protect devices from malware that uses exploits to spread and infect other devices. Mitigation can be applied to either the operating system or to an individual app. Many of the features that were part of the [Enhanced Mitigation Experience Toolkit (EMET)](emet-exploit-protection.md) are included in exploit protection.
[Exploit protection](exploit-protection.md) helps protect devices from malware that uses exploits to spread and infect other devices. Mitigation can be applied to either the operating system or to an individual app. Many of the features that were part of the Enhanced Mitigation Experience Toolkit (EMET) are included in exploit protection. (The EMET has reached its end of support.)
This article helps you enable exploit protection in audit mode and review related events in Event Viewer. You can enable audit mode to see how mitigation works for certain apps in a test environment. By auditing exploit protection, you can see what *would* have happened if you had enabled exploit protection in your production environment. This way, you can help ensure exploit protection doesn't adversely affect your line-of-business apps, and you can see which suspicious or malicious events occur.

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 Exploit protection](emet-exploit-protection.md) for more information on how Exploit protection supersedes EMET and what the benefits are when considering moving to exploit protection on Windows 10.
Many of the features in the [Enhanced Mitigation Experience Toolkit (EMET)](https://technet.microsoft.com/security/jj653751) are included in exploit protection. In fact, you can convert and import existing your EMET configuration profiles into exploit protection. To learn more, see [Import, export, and deploy exploit protection configurations](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/import-export-exploit-protection-emet-xml).
