VPN and proxies: how to choose a VPN protocol for your tasks (speed/mobility/security)?

Choosing the optimal protocol for specific networking tasks requires a clear understanding of your individual priorities, whether it is maximum data transfer speed, mobility, or uncompromising security. Start by outlining your basic requirements: determine which specific resources need to run stably, and set strict limits on budget, performance, and encryption level.

To achieve maximum connection speed, modern lightweight protocols like WireGuard are best, as they place minimal load on the device's CPU and provide instant response. If mobility is important to you—when a device frequently switches between Wi-Fi networks and 4G mobile internet—the optimal choice would be the Shadowsocks protocol or its modifications, which are resilient to connection drops.

When absolute security and the need to mask the very fact of using a secure connection come to the forefront, you should use protocols with traffic camouflage resembling regular HTTPS, such as VLESS with XTLS technology. This allows you to successfully bypass complex blocking systems and deep packet inspection (DPI) without sacrificing the privacy of user data.
