Web filtering tools handling ever-larger jobs

摘要

From the time the World Wide Web took off in the mid-90s, corporations began looking for ways to filter out access to its more lurid displays, but IT managers who use filters today say they're good for much more than blocking access to porn. Because keeping company resources safe from spy-ware, adware and phishing is of growing importance, Web filter technologies are keeping up by blocking sites known to be engaged in those types of threats. Filters have expanded to block peer-to-peer file sharing sites, which pose copyright concerns and often spread adware. Companies using Web filters expect them to play an ever-larger role in enterprise protection.
