DrayTek\'s Web Content Filtering (WCF) facilities enable you to protect your network and your users from web content according to your preferences. There are many reasons for doing this, for example: Reason to Block Example Unsuitable Adult material for children Undesirable Time wasting sites for employees Dangerous Malware or virus-ridden web sites Fraudulent Confidiential data leaving your network As DrayTek WCF is performed by your router - your point of entry to the Internet - it is far more difficult to circumvent than software solutions installed on each client/PC and applies to guest PCs too (laptops etc.). Blocking/filtering can be selective for certain computers, users or groups too, so that, for example, managers can have less filtering imposed than other users and time schedules can apply these content filtering for specific time periods only (the facilities and granularity of this depends on the specific model of router selected).
