Web Reputation Services (WRS) scrutinizes URLs before users access potentially dangerous websites, especially sites known to be phishing or pharming sites. Employing WRS, Cloud Edge provides real-time protection, conserves system scanning resources, and saves network bandwidth by preventing the infection chain or breaking it early. Web Reputation technology guards end-users against emerging web threats. Because a Web Reputation query returns URL category information (used by URL filtering), Cloud Edge does not use a locally-stored, URL database.
Web Reputation technology assigns reputation scores to URLs. For each accessed URL, Cloud Edge queries Web Reputation for a reputation score and then takes the necessary action, based on whether this score is below or above the user-specified sensitivity level.
Cloud Edge provides anti-phishing and anti-pharming protection through Web Reputation, if it is enabled.
The web reputation database resides on a remote server. When a user attempts to access a URL, Cloud Edge retrieves information about this URL from the web reputation database and stores it in the local cache. Having the web reputation database on a remote server and building the local cache with this database information reduces the overhead on Cloud Edge and improves performance.
