Open source innovator and SNORT® creator, Sourcefire, Inc. (Nasdaq:FIRE), a leader in Enterprise Threat Management, today announced that the Sourcefire Vulnerability Research Team (VRT) has delivered rules to protect Sourcefire customers and Snort users from the four critical Microsoft vulnerabilities announced today. These vulnerabilities impact Microsoft Office and Microsoft Office Web Components.

“Sourcefire is a recognized leader in delivering same day coverage for Microsoft Tuesday vulnerabilities, and we work diligently to ensure that our customers and Snort users are protected from the latest threats as quickly as possible,” said Matt Watchinski, Director of the Sourcefire Vulnerability Research Team. “Companies need to take a proactive approach to protecting their customers and assets, and they need to demand that their technology providers are just as dedicated to preventing attacks before they occur. Sourcefire partners with our customers to help them create the best possible defense against both known and unknown threats, so that their critical information, as well as that of their employees, partners and customers is safe from theft.”
