Why do we need net filtering?

The internet is a global access system with no central administration. Censorship levels vary from country to country, culture to culture. Many countries have created their own set of rules for what can be shared on the internet, based on the country’s moral standards and political outlook. The very nature of the internet, which makes it such an invaluable information resource, also makes it difficult to regulate and control.

The challenge for governments worldwide is to allow people access to the internet but try to ensure that the content isn’t harmful or offensive to each particular country. By and large, however, the best way to make sure you and your family only view content that is acceptable to you is to install a net filtering package and customise it for your particular needs.
