Internet Filtering :

No other IT topic has triggered as much controversy in recent years; to filter or not to filter. Frankly, in a corporate environment, the discussion should be moot - filter out all non-business activities. This improves productivity and reduces liability. For institutions serving the public, this discussion is much more emotional. The argument is typically "Freedom of information versus liability avoidance". Our recommendation is to acquire and implement a filtering solution regardless of your decision to filter. The better filtering solutions have excellent report generation capabilities that look at who is going where and when. If your decision is not to filter, having this information will either enforce your belief you do not need it or give you pause for thought. In any case, make sure you have your Internet Usage policy in place and acknowledged by all employees.
