Egress proxying is a service that runs on Google Global Cache nodes. Google uses this service to analyze and identify potentially unsafe content on the web, as well as gathering performance data that helps improve Google services.
By enabling this service, you allow Google to use a small amount of the GGC's Internet bandwidth to gather this data. Enabling egress proxying helps to protect Internet users, and can potentially reduce malware associated traffic on your network.
