All Website Content Filters Work the Same, Right?
Nope! There are many different methods of content or web filtering: most involve using a big list of banned domain names, and IP Addresses. Some take it a step further and will have regular expression checks on the URL to see if anything matches a list of blacklisted words.
Most of these are really ‘Web Filters’, as they do not look at the content contained in the page, but merely the URL or IP Address.Very few offer TRUE Intelligent Content Filtering and porn blocking where the actual contents of the page are analyzed for content and the filter dynamically determines whether the page should or should not be blocked. NetSentron is one of the few that offers TRUE Intelligent Content Filtering.
