Cisco security appliances protect customers during the critical period between the first exploit of a virus outbreak and the release of vendor antivirus signatures. Email that is managed by Cisco and end users who are protected by Cisco Web Security Appliances will not be impacted by these attacks. Cisco security appliances are automatically updated to prevent both spam email and hostile web URLs from being passed to the end user.
