This best practices document improves upon Symantec's previous content scanning recommendations for integrating Content Analysis appliances with the Secure Web Gateway (SWG) solution, which includes ProxySG, Advanced Secure Gateway, and SWG virtual appliances. These best practices provide a more secure and customizable policy model for bypassing content scanning to lower risk and improve user experience, as well as ways to save resources by excluding low-risk/high-volume traffic.
Symantec provides two policy templates to bypass content scanning for low risk/high volume content: a WebFilter template and an Advanced Intelligence Services template. The webguide version of this document includes the templates in two zipped files. If you prefer to use the PDF, download the template (attached to this article) appropriate for your deployment.
