Policy Guide/Page 4 Symantec WSS Policy Guide The Symantec Web Security Service solutions provide real-time protection against web-borne threats. As a cloud-based product, the Web Security Service leverages Symantec's proven security technology, including the WebPulse™ cloud community. With extensive web application controls and detailed reporting features, IT administrators can use the Web Security Service to create and enforce granular policies that are applied to all covered users, including fixed locations and roaming users. If the WSS is the body, then the policy engine is the brain. While the WSS by default provides malware protection (blocks four categories: Phishing, Proxy Avoidance, Spyware Effects/Privacy Concerns, and Spyware/Malware Sources), the additional policy rules and options you create dictate exactly what content your employees can and cannot access—from global allows/denials to individual users at specific times from specific locations.
