A proxy server is a system or router that provides a gateway between users and the internet.
It can help you access content that is restricted by geographic location or censorship, as well as protect your privacy and security by hiding your IP address and preventing hackers, ISPs, advertisers, and other third parties from tracking your online activity.
The main difference between a proxy and a VPN is that a proxy works only with a single app or service, while a VPN secures all your internet traffic and encrypts it for extra security and privacy.
A proxy server may be faster and cheaper than a VPN, but it also has more limitations and risks. A VPN service may be slower and more expensive than a proxy, but it also offers more features and benefits.
