EMET is a free tool designed to help IT professionals protect systems from common threats, even in older software. EMET lets IT pros add new and existing security technologies to software to help protect against past and future exploits. The newest version also provides a central interface to make it easier to manage threats.
Version 2 of EMET will be available later this month. Check the Security Research and Defense blog for updates on the exact release date.
