Cisco Security Intelligence Operations analysts examine real-world e-mail traffic data that is collected from over 100,000 contributing organizations worldwide.  This data helps provide a range of information about and analysis of global e-mail security threats and trends.  Cisco will continue to monitor this threat and automatically adapt IronPort systems to protect customers.  This report will be updated if there are significant changes or if the risk to end users increases.

Cisco IronPort Virus Outbreak Filters protect customers during the critical period between the first exploit of a virus outbreak and the release of vendor antivirus signatures.  E-mail that is managed by Cisco and end users who are protected by Cisco IronPort web security appliances will not be impacted by these attacks.  Cisco IronPort appliances are automatically updated to prevent both spam e-mail and hostile web URLs from being passed to the end user.
