The popular opinion is that OpenVPN is the best dedicated IP VPN protocol. We recommend using OpenVPN because it offers more robust encryption methods (AES-256 2048 bit). Its speed is much faster than that of other protocols. It also works across all platforms and devices.WireGuard is another popular VPN protocol and can be an excellent alternative to OpenVPN. WireGuard's speed is significantly higher than OpenVPN, but WireGuard has a limited selection of algorithms. Nevertheless, WireGuard offers improved speed and a smaller potential for security breaches.Although L2TP and IPsec are complete protocols with specific characteristics, they are often used together. Where firewalls block L2TP, IPsec comes to the rescue. So that, L2TP/IPSec are combining their functionality and creating a secure communication channel.Socks5 Proxy is suitable only for specific purposes, not general usage. This option is much slower than other protocols and provides low security.PPTP is easy to set up and operates fast, with native support on many devices. However, weaker encryption makes PPTP less secure than other protocols.
