Citadel is two layers in one app: an AI that reads the network before you connect, and an enterprise-grade tunnel that makes your phone disappear. Know the room, then vanish into it.

ONE-TAP VPN Tap once and you're inside a WireGuard tunnel. On public WiFi your phone normally broadcasts your real IP, your carrier, your location. On Citadel, all of it goes dark — your connection looks like plain datacenter transit. No carrier identity. No device fingerprint. No home-city geolocation. Your phone stops looking like your phone.

AI THAT CHECKS THE NETWORK FIRST The second you launch, an instant safety gate scans the network — you'll know in about 14 seconds. Then a deeper AI sweep keeps hunting for what's hidden: rogue devices, dangerous open ports, threats most people never see. Every device on the network, visible. You decide who to trust before you send a single packet.

WHY CHACHA20 The same cipher WireGuard was built around and the one Signal uses to protect your messages. Fast on mobile, brutally hard to break. Most VPNs show you a lock icon. We show you ChaCha20 — right on screen, so you see exactly what's protecting you.

BUILT FOR THE ROAD Airports, hotels, coffee shops, conference halls — used in over 50 cities. If you work from anywhere, this is the layer between you and every network you don't control.

WE DON'T WATCH YOU Zero collection. We don't log your traffic, we don't track you, we have nothing to sell. The tunnel encrypts your connection and that's where it ends. Your privacy isn't our product.

Know before you connect. Tunnel up. Disappear.
