On the flip side, SOCKS5 comes with 3 types of authentication, including: SOCKS4 doesn’t support it, making it less secure. One of the major differences between SOCKS5 and SOCKS4 protocols lies in authentication. In simple terms, it means SOCKS5 is more versatile and can be used even for torrenting, typical browsing, or sending emails. SOCKS5 proxy, supports not only UDP/TCP but also requests like HTTP, SMTP, FTP, HTTPS, and POP3. Then, layer 4 supports TCP/UDP connections, while layer 5 i.e. To give you a rough idea of other layers, let’s mention layer 7, which is an SSL proxy. Since it operates on layer 5, it “cares” only about information from that layer, while data from lower layers are irrelevant, some of which include your ARP or ping, for example. Of course, there is the SOCKS4 protocol as well, but SOCKS5 is more secure. The number “5” in the name means this is the layer 5 protocol. This immediately makes it more secure than “standard” proxies that you can find online. The good thing about SOCKS5 is that it doesn’t interpret the traffic that flows between you and the intermediary server. From here, network packets are exchanged between you and that server, while this firewall keeps things secure. Furthermore, SOCKS5 takes advantage of the TCP/UDP connection, which is then established with another server behind the firewall. Instead, it’s designed to work with every app or website. What’s more, this proxy works on the system level, which means it doesn’t have an effect only inside the browser. Much like “normal” HTTP proxies or any other, it’ll route your traffic through an intermediary server and hide your original IP address. The word “SOCKS” here has nothing to do with your socks. First, we need to explain what is SOCKS5 because we don’t think many people are even aware of its existence. SOCKS5 vs HTTP Proxy: Is SOCKS5 Better?.Best SOCKS5 Proxy VPN Providers for 2023.
