[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.

(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.
