Performance
Smart Multi-Path Routing
Traffic is balanced across top-performing tunnels to avoid congestion and maintain throughput.
FEATURE ENGINE
Advanced free VPN capabilities for daily users and security teams.
From kill switch and DNS hardening to smart route healing and stealth transport, ProTun keeps sessions private and stable at zero cost.
CORE CAPABILITIES
Free security and performance features engineered for stability.
Stealth
Adaptive Obfuscation
Protocol fingerprints are reshaped dynamically to keep links stable in restrictive networks.
Privacy
Kill Switch + DNS Shield
Instant leak prevention if connectivity changes, with encrypted DNS and resolver fallback.
Control
Per-App and Split Tunneling
Choose which apps go through VPN and which use direct access for local performance.
Reliability
Always-On Tunnel Health
Continuous checks for jitter, packet loss, and route quality with automatic recovery.
Trust
Zero-Log Operation
No activity logs, transparent policy, and minimal telemetry by default.
FEATURE KEYWORDS
VPN kill switch, split tunneling, encrypted DNS, and no-log architecture.
These are high-intent VPN feature queries. ProTun ships each one as a production feature so users searching for secure VPN controls can match intent to real capability.
Privacy Enforcement Pipeline
Traffic, DNS, and route-state are continuously evaluated so leaks are blocked before they happen.
- Always-on kill-switch behavior
- Encrypted DNS with resolver fallback
- Policy-based per-app routing
Performance Optimization Pipeline
Route telemetry and congestion signals adjust tunnel paths in real time for consistent speed.
- Multi-path route probes
- Automatic region failover
- Low-jitter lane preference
| Feature Layer | What It Does | User Value |
|---|---|---|
| Transport Layer | Adaptive encrypted tunnels with route healing | More stable sessions in unstable networks |
| Privacy Layer | Kill-switch, DNS hardening, no activity logs | Reduced exposure on public and hostile networks |
| Control Layer | Per-app policies and split tunnel rules | Better local performance and flexible workflow |
| Recovery Layer | Automatic tunnel recovery and region failover | Lower downtime for calls, streams, and games |
Leak Prevention Layer
Firewall-level traffic controls block accidental leakage when network state changes suddenly.
High-Speed Tunnel Fabric
Parallel route probes help maintain throughput even when a specific path degrades.
Global Route Intelligence
Control-plane telemetry updates route choices continuously for lower jitter and fewer drops.
Recommended security baseline
- Enable auto-connect and kill-switch on all endpoints.
- Use split tunneling for local apps that do not require VPN.
- Choose nearest low-latency region, then pin a backup region.
- Keep app versions updated for latest protocol hardening.
