Securing web access is no longer just about limiting an organisation's legal exposure or maintaining user productivity.

With the growing threat from malware, spam and other criminal activity, the web has become a significant threat vector and must be secured to protect the rest of the organisation.

Traditional web filters that used to manage user activity are no longer effective against these new threats as they do not scan in real-time, leaving the user and the company exposed to unknown malware, zero-day threats and drive-by attacks.

This whitepaper looks at the history of web filtering, what's changed and why. In addition to describing emerging risks and some of the older threats that still exist, the whitepaper looks at how technology has developed to protect the organisation.
