        The Enhanced Mitigation Experience Toolkit (EMET) helps raise the bar against attackers gaining access to computer systems. EMET anticipates the most common actions and techniques adversaries might use in compromising a computer, and helps protect by diverting, terminating, blocking, and invalidating those actions and techniques. EMET helps protect your computer systems even before new and undiscovered threats are formally addressed by security updates and antimalware software. EMET benefits enterprises and all computer users by helping to protect against security threats and breaches that can disrupt businesses and daily lives.

        Helps raise the bar against attackers. EMET helps protect against new and undiscovered threats even before they are formally addressed through security updates or antimalware software. EMET includes 12 security mitigations that complement other defense in-depth security measures, such as Windows Defender and antivirus software. EMET installs with default protection profiles, which are XML files that contain preconfigured settings for common Microsoft and third-party applications.

        Works well for the enterprise. Enterprise IT professionals can easily deploy EMET through Microsoft System Center Configuration Manager and apply Group Policies in Windows Active Directory to comply with enterprise account, user, and role policies. Administrators can customize and configure EMET deployments and determine which applications they want to protect through which mitigation techniques.

        Even for enterprise legacy software that cannot easily be rewritten, or for software being phased out where the source code is not available, EMET provides mitigation protections. The reporting capabilities in EMET are provided through a component called the EMET Agent, which allows enterprises to create logs and notifications for audit purposes. EMET customer support is available through Microsoft Premier Support Services. For more information on deployment EMET, also visit the EMET Knowledge Base Article: KB2458544

        Helps protect in a wide range of scenarios. EMET is compatible with most commonly used third-party applications at home and in the enterprise, from productivity software to music players. EMET works for a range of client and server operating systems used at home and in the enterprise. When users browse secure HTTPS sites on the Internet or log on to popular social media sites, EMET can help further protect by validating Secure Sockets Layer (SSL) certificates against a set of user-defined rules.

        EMET 5.1 release includes new functionality and updates, such as:
        - Attack Surface Reduction (ASR), to limit the attack surface of applications and reduce attacks.
        - Export Address Table Filtering Plus (EAF+), to improve and extend the current EAF mitigation.
        - 64-bit ROP mitigations, to anticipate future exploitation techniques.
        - Several security, compatibility and performance improvements.
