ProxyGuard - HTTP Proxy Manager is a free Chrome add-on designed to simplify the management of HTTP proxies. This tool allows users to lock a system-wide HTTP proxy by setting the host, port, and credentials just once. Its primary function is to enforce proxy usage, ensuring that all web traffic is directed through the specified proxy server. This is particularly useful for users who need to maintain consistent browsing privacy or comply with network policies.

The add-on also prevents users from making unauthorized changes to proxy settings, adding an extra layer of security. With a straightforward interface, ProxyGuard enables quick configuration and reliable enforcement of proxy settings, making it an essential tool for individuals and organizations that require stringent control over their internet connections.
