How to Bypass VPN Blocks with Hybrid Obfuscation

As internet censorship becomes more sophisticated, standard VPN protocols are being blocked by regional firewalls and corporate networks. Information freedom depends on a VPN's ability to remain invisible.

The Evolution of VPN Blocking

Modern firewalls use Deep Packet Inspection (DPI) to identify the "handshake" of protocols like OpenVPN or WireGuard. Once identified, the traffic is throttled or dropped. To combat this, FastVPN developed its **Hybrid Obfuscation Layer**.

NTRU-Hybrid Masking

Our technology doesn't just encrypt your data; it morphs the packet structure. To an ISP or firewall, your VPN traffic looks like standard, non-attributable HTTPS telemetry data. This is achieved through real-time packet padding and header randomization.

Staying One Step Ahead

Traditional "obfuscated servers" often use slow proxy wrappers that add significant latency. FastVPN's approach is kernel-integrated, meaning the obfuscation happens at the same time as encryption, maintaining **10Gbps line speeds** while remaining undetected.
