VPN Protocol Comparison: VLESS, Shadowsocks, Hysteria2

Updated: May 15, 2025

Choosing the right VPN protocol is key to a stable and fast connection. In this article, we’ll break down three modern protocols used by Tainet.

Tainet Protocol Comparison

VLESS + Reality

VLESS is a lightweight protocol from the creators of V2Ray. Combined with Reality, it provides excellent traffic masking and security.

How it works

Reality allows VPN traffic to masquerade as regular HTTPS traffic to popular websites. When you connect, your connection looks like a normal visit to google.com or microsoft.com.

Pros

  • Maximum traffic privacy
  • No need for your own TLS certificates
  • Low encryption overhead

Cons

  • Slightly more complex setup
  • Requires compatible client (v2rayN, Hiddify, Nekoray)

When to use

Ideal when you need maximum privacy and traffic masking in any network.


Shadowsocks 2022

Shadowsocks is a time-tested protocol. The 2022 version features AEAD encryption and replay attack protection.

How it works

Shadowsocks encrypts traffic and transmits it via regular TCP or UDP. To an external observer, it looks like a random data stream.

Pros

  • Easy to set up
  • Wide client support
  • Stable speed

Cons

  • Less sophisticated masking than VLESS
  • Recognizable traffic patterns

When to use

Good for everyday privacy when VLESS+Reality is overkill.


Hysteria2

Hysteria2 is a QUIC-based protocol optimized for unstable networks and high speed.

How it works

QUIC (the same protocol used by HTTP/3) runs over UDP. Hysteria2 adds obfuscation and optimizations for working under packet loss conditions.

Pros

  • Excellent performance on mobile internet
  • Fast recovery after disconnections
  • UDP-based - better for video and gaming

Cons

  • UDP may be restricted by some networks
  • Higher battery consumption on mobile

When to use

Ideal for mobile internet, streaming, and online gaming.

In Tainet, all three protocols are available on all plans. You can switch between them at any time through your dashboard.


Summary

There’s no “best” protocol - there’s the right one for your situation. Start with VLESS+Reality for maximum privacy, or Hysteria2 if speed on mobile internet is important.

All protocols are available free for 24 hours after registration.
