Internet filtering software is a software designed to restrict access to certain websites or online content. It blocks specific websites or categories of content that are considered inappropriate, offensive, or harmful.

This type of software can be set up to block websites with specific keywords or phrases, or to block entire categories of content like pоrnography, gambling, or social media.

Organizations, like schools and businesses, commonly use internet filtering software to limit access to websites or content that could distract employees or students from their work or studies. It is also used by parents to safeguard their children from accessing inappropriate online content.
