VPN Obfuscation Explained
Governments and ISPs use deep packet inspection to detect and block VPN traffic. Obfuscation is the countermeasure.

What Is Deep Packet Inspection
DPI examines the full content and headers of network packets to identify the type of traffic. Governments in China, Iran, Russia, and UAE use DPI to detect VPN protocols by their characteristic traffic patterns.
How Obfuscation Works
VPN obfuscation disguises VPN traffic to look like regular HTTPS browsing or random data. This prevents DPI systems from identifying and blocking VPN connections. Different VPNs use different obfuscation techniques.
CasperCloak Obfuscation
CasperCloak goes beyond basic obfuscation. It generates traffic patterns that are statistically indistinguishable from regular HTTPS traffic, defeating both signature-based and statistical analysis DPI methods.
Frequently Asked Questions
Does obfuscation slow down my connection?
There is a small overhead from the additional processing, but CasperCloak is optimized to minimize impact. Most users will not notice a meaningful speed difference.
