Technology That Works
Simple explanations of how we bypass censorship without technical jargon.
🔐Why VLESS + QUIC is Hard to Block
VLESS Protocol
Traditional VPNs create a recognizable pattern that censorship systems can detect. VLESS makes your traffic look exactly like normal HTTPS browsing—the same kind of connection you use when visiting any secure website.
- ✓No encryption overhead—faster speeds
- ✓Looks identical to regular web traffic
- ✓No digital "fingerprint" for DPI to detect
QUIC Protocol
QUIC is the next-generation internet protocol built on UDP. It establishes connections faster than traditional TCP and encrypts even the metadata that other protocols expose.
- ✓Faster connection recovery after blocks
- ✓Built-in encryption at all levels
- ✓Better performance on unstable networks
🎭How SNI Masking Tricks DPI
When you connect to a website, your device sends a "Server Name Indication" (SNI) that tells the server which site you want to visit. Censorship systems read this to block specific destinations.
Without Masking
With AzadiVPN
Your actual destination is encrypted inside the tunnel. The censor only sees you connecting to a popular, allowed service.
🌐What Happens During a Shutdown
Internet shutdowns work by blocking known VPN servers and throttling suspicious traffic patterns. Here's how we stay ahead:
Auto-Detection
Our system continuously monitors server accessibility from restricted regions.
Smart Rotation
If a server is blocked, your client automatically switches to a working one.
Reserve Servers
We maintain backup servers that are activated during mass blocking events.
