The primary difference between a proxy and a VPN is how they handle your internet traffic and provide security and privacy.A proxy acts as an intermediary between your device and the internet. It forwards your internet traffic through a server before it reaches its final destination. A proxy can be used to hide your IP address and location, as the website or service you are accessing will only see the IP address of the proxy server. However, a proxy does not encrypt your internet traffic, which means that your online activities may still be visible to third parties.
