The Hypertext Transfer Protocol (HTTP) links websites and other resources on the World Wide Web. The benefits for people using SOCKS5 proxies, however, are minimal. Commercial proxy servers, for example, can use SOCKS5 to ensure only paying customers can connect to their servers. It provides proxy operators various ways to authenticate users, thus giving them greater control over who uses the server. SOCKS4 remains the most common version of SOCKS used by proxy servers, but SOCKS5 is the latest version. Support for HTTPS is built into the SOCKS protocol, and it is often used to secure connections to SOCKS proxy servers. Together with the high bandwidth often consumed while torrenting, public SOCKS proxies can often suffer from a high server load. SOCKS’s ability to proxy BitTorrent traffic, in particular, is a popular reason to use SOCKS proxies, and they are sometimes known as “torrent proxies”.

VPN companies, such as Proton, spend a great deal of time and money building large and highly secure network infrastructure and developing advanced features for their community.Īs discussed below, commercial (non-VPN) proxy services do exist, but the advantages of VPN technology over regular HTTP and SOCKS proxy setups mean this sector is far less developed (and therefore also far less open to scrutiny) than the VPN industry. VPN providers are commercial entities, often subject to a great deal of public scrutiny.VPNs use highly secure VPN protocols, such as OpenVPN and WireGuard, that provide additional layers of security for your data rather than just the simple HTTPS used to secure most proxy connections.A VPN protects your entire internet connection, while most proxies must be configured on a per-app basis (for example, your browser or BitTorrent client).The key differences between a VPN and most other kinds of encrypted proxy setups are: If you are familiar with how VPNs work, this may all sound very familiar. The classic example of a reverse proxy is an office intranet that can only be accessed from the outside via a single (reverse proxy) server.Īll the proxies discussed in the rest of this article are forward proxies. A reverse proxy, on the other hand, acts as a gateway between the internet and a small group of servers. Technically speaking, this describes a forward proxy that sits between your computer and the internet. This is why it is crucial that you only use a trustworthy VPN to access the internet. Most importantly, since your traffic passes through and is encrypted and decrypted by the proxy server, whoever runs the proxy server can monitor your internet activity. It also can’t see the contents of your internet traffic (for example, files you are downloading).It can only see that you have connected to a proxy server. Your internet service provider (ISP) cannot see what you do on the internet.The connection between your computer and a proxy server is not always secured using encryption, but it often is. Can be used to “spoof” your real geographic location.Hide your real IP address from websites (and other internet resources, such as games servers, BitTorrent peers, and email servers) you visit on the internet.This means that your internet traffic passes through the proxy server and enters the internet using its IP address and physical location. What is a proxy?Īs noted above, a proxy is a server that sits between your device and the internet. In this article, we look at what a proxy is and provide an overview of the different kinds of proxy that are available.

Although inaccurate (and as a result, confusing), VPNs are often contrasted to proxies. A virtual private network (VPN) server is a specific kind of proxy, but many other kinds of proxy exist. A proxy is any server that sits between your device and a wider network, such as the internet.
