A proxy server acts as a gateway between you and the internet. It’s an intermediary server separating end users from the websites they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy.
Web content filters can be considered a form of DLP to some extent. They intend to prevent users from sending out sensitive data to other websites, while also filtering out potentially harmful or malicious data or information from a website. They can also prevent access to sites that have content that might be deemed objectionable, unnecessary, or harmful. For example, it is common for organizations to prevent connections to pornographic websites and web torrents. Many organizations ban social media sites on work computers. We have worked with several organizations that also ban access to hacker websites, as they do not want malicious tools downloaded onto their network.
Similarly, the content filters are the programs that help you filter the content which is acceptable for viewing and accessing. When implemented, a content filter restricts a user from accessing inappropriate Internet sites while allowing access to desired sites. It is the system administrator who decides, what is to be seen and what is to be blocked or prevented.
