Norton Safe Web (sometimes abbreviated NSW) is a service developed by Symantec Corporation that is designed to help users identify malicious websites. Safe Web delivers information about websites based on automated analysis and user feedback.
The software debuted as a public beta in 2008, and is now included in current versions of Norton Internet Security and Norton 360. A limited, standalone version of Safe Web, known as Safe Web Lite, is available as a freeware. Safe Web operates as a web browser plugin, and requires Internet Explorer 6 or Firefox 3 or later. The 2012 release of Safe Web Lite added Google Chrome support.
