# Introduction

SecurQbit is a privacy VPN built for the networks that block everything else. Its tagline says it plainly: **the VPN that gets through when other VPNs can't.** Where conventional VPNs are easily fingerprinted and dropped by deep packet inspection (DPI), SecurQbit shapes its traffic to look like ordinary web browsing — so the tunnel survives where it matters most.

## The problem it solves

Modern censorship and corporate firewalls rarely block VPNs by IP address alone. Instead they inspect the *shape* of your traffic. DPI systems recognize the handshake signatures of common VPN protocols and silently throttle or kill those connections. The result is a VPN that connects on your home Wi-Fi but fails on a hotel network, a university campus, a strict corporate LAN, or inside a nationally filtered internet.

SecurQbit treats DPI as a first-class adversary. Its obfuscation layer produces adaptive, encrypted traffic that is statistically indistinguishable from standard HTTPS, giving DPI nothing recognizable to act on.

## Who it's for

- Travelers and remote workers behind hotel, airport, or hotspot captive portals.
- People in regions with heavy network filtering who need reliable access.
- Privacy-focused users who want zero logging and crypto payment options.
- Anyone whose current VPN connects at home but dies on restrictive networks.

## Key features

- **[Firewall bypass & obfuscation](/firewall-bypass)** — adaptive HTTPS-mimicking traffic that evades DPI on corporate firewalls and national censorship systems.
- **[No-logs & privacy](/no-logs-privacy)** — zero-logging infrastructure on RAM-only servers; nothing is written to disk.
- **[Split tunneling](/split-tunneling)** — route only the apps you choose through the VPN.
- **[Encryption & protocols](/encryption)** — modern AEAD ciphers with forward-secret key exchange.
- **[Performance & networks](/performance)** — network-aware optimization tuned for 3G, congested Wi-Fi, and hotel networks.

> **Note:** Obfuscation is a defensive, legitimate censorship-circumvention feature. Always comply with the laws and policies that apply to you.

## Supported platforms

SecurQbit ships native apps for **iOS 20 and later** and **Android 10 and later**, both built directly on the platform VPN frameworks for low overhead and reliable background operation. See [Installing SecurQbit](/installation) for system requirements.
