Citadel VPN & WiFi Security

Is someone on your WiFi right now that shouldn't be?
Is the public WiFi you're on protecting you? You don't know. With Citadel, you do.

Citadel tells you in seconds. Open the app, tap scan, and see every device on your network — phones, laptops, smart TVs, cameras, and anything else that's hiding.

Your router won't tell you who's on your WiFi. Your phone won't either. Citadel will.

KNOW IF YOU'RE EXPOSED
On launch, an instant safety gate scans the network — you'll know in about 14 seconds. Is client isolation shielding you from other guests, or can every device see yours? Citadel gives you the verdict, then a deeper AI sweep hunts for what's hidden: rogue devices, dangerous open ports, threats most people never see. You decide who to trust before you send a single packet.

TRAINED ON REAL ATTACK TOOLS
Citadel recognizes the network signatures of Kali Linux, ParrotOS, Metasploit, Burp Suite, SpiderFoot, Nmap/Zenmap, and Wireshark activity — and flags open proxy services, the backbone of interception tools like OWASP ZAP and mitmproxy. New tool fingerprints ship with every update.

ONE-TAP VPN
Tap once and you're inside a WireGuard tunnel. Servers in the US and Europe: Citadel connects you to the fastest and, if it ever stops responding, switches you to the other automatically — even with your phone locked. 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.

WHY CHACHA20
The cipher WireGuard was built around — the same one TLS 1.3 uses to secure most of today's encrypted web. 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 — over 500,000 networks scanned. If you work from anywhere, this is the layer between you and every network you don't control.

ZERO TRAFFIC LOGS
The tunnel encrypts your connection and that's where it ends. No browsing history, no activity logs, nothing to sell. Your privacy isn't our product.

You have the right to defend yourself. Know before you connect.
