In the old Web 1.0 days, websites were essentially static - their content derived from well-defined sources within a single organisation. This is no longer the case. Mashups and other indirect construction techniques mean that a Web 2.0 site might be composed of content from any number of sources.
Some of those sources might host malware.
Consider a simple case – iGoogle for instance. There are an endless supply of gadgets which may be joined together to form a personalised interface. Few, if any are under Google's control.
This means that simplistic identification of unsafe sites by name alone is no longer enough.
The Websense V10000 takes a much more proactive position when it comes to such sites – each sub-component is analysed separately and, potentially, only 5 of the 8 gadgets on some mashup site will be delivered to the user.
This device also takes on the features of previous Websense devices, permitting time-sensitive access to certain categories of site (shopping or travel sites for instance) and banning others outright.
"Effective protection in today's Web 2.0 world requires the ability to analyse Web content in real-time to recognize threats and inappropriate content 'on the fly,' even content never before classified," said John McCormack, senior vice president of product development. "The Websense V10000 secure Web gateway appliance leverages our unprecedented visibility into the threat environment to deliver more effective protection from inbound threats and outbound data loss."
That's right, it can also analyse outbound data. Not just phone-home type traffic, but also employee messages which might indicate non-approved activity.
