ASTRO VPN is built around six protocols: our exclusive AstroCore, WireGuard, Hysteria2, IKEv2/IPSec, Shadowsocks and Xray. They adapt to changing network conditions and keep your connection fast, stable and secure.
- Includes AstroCore, our own proprietary protocol
- Built to get through censorship and restrictive networks
Protocols at a glance
Multi-protocol architecture
Six protocols work together, adapting to changing network conditions and optimizing routing in real time to keep latency low.
Beats censorship
Xray and Shadowsocks disguise your traffic, making it harder for deep packet inspection and restrictive firewalls to detect and block.
Built for speed
WireGuard and Hysteria2 deliver fast, low-latency connections on mobile and desktop.
Stays connected
IKEv2/IPSec keeps your connection secure while switching between Wi-Fi and cellular networks.

Which protocol fits your situation
Each protocol is strongest in a different situation. Here is where each one helps most.
speed
WireGuard and Hysteria2
WireGuard is lightweight and easy on battery. Hysteria2 runs on QUIC for low latency, even on unreliable networks.

Stealth
Xray and Shadowsocks
Both disguise your traffic as regular internet activity, so restrictive networks find it much harder to detect and block.

Stability
AstroCore and IKEv2/IPSec
AstroCore stays reliable when other protocols face throttling. IKEv2/IPSec keeps you connected when you switch networks.

Protocol details
ASTRO VPN's proprietary protocol, engineered for maximum security, exceptional stability and reliable performance even when other protocols face restrictions, throttling or network instability.
A modern, lightweight VPN protocol with advanced cryptography. It delivers ultra-fast speeds, lower battery consumption and stable connections across mobile and desktop devices.
A next-generation VPN protocol built on QUIC. It delivers exceptional speed, low latency and stable performance even on unreliable networks.
A next-generation protocol designed to mimic normal internet traffic. It helps bypass deep packet inspection (DPI) and advanced censorship systems with greater reliability.
A lightweight encrypted proxy that disguises traffic as regular HTTPS communication, making detection and blocking by restrictive firewalls significantly more difficult.
Optimized for mobile devices. It automatically maintains a secure connection while switching between Wi-Fi and cellular networks, without interruption.
