Defeat Censorship with VyprVPN’s Chameleon™ Protocol

Proprietary Technology Defeats VPN Blocking and Government Censorship

How Chameleon™ Defeats VPN Blocking

At VyprVPN we believe everyone should have access to a free and open internet, and be able to bypass restrictive censorship imposed by governments. That‘s why our engineers developed a remarkable proprietary VPN protocol called Chameleon.

The protocol scrambles OpenVPN™ packet metadata to ensure it’s not recognizable via deep packet inspection (DPI), while still keeping it fast and lightweight. Chameleon™ technology uses the unmodified OpenVPN™ 256-bit protocol for the underlying data encryption. The result is that VyprVPN users are able to bypass restrictive networks put in place by governments, corporations and ISPs to achieve an open internet experience without sacrificing the proven security for which OpenVPN™ has long been known.

Chameleon™ with Smart IP

We built Chameleon™ with Smart IP to help users in strict censorship markets such as China. Chameleon™ with Smart IP makes it more difficult for the great Firewall to detect and block VyprVPN, and offers users a consistent and quality connection experience. Chameleon™ with Smart IP works by changing the VyprVPN server IP periodically throughout your session, all without dropping the connection. This work goes on “behind the scenes,” so you won’t notice any impact to your experience. Chameleon™ with Smart IP is enabled by default when using the Chameleon™ protocol, and applies to select server locations.

What Users Are Saying About Chameleon™

"Chameleon is currently the only protocol that consistently allows me to connect to the Internet from within China. It is essential the I'm able to access Web resources like Youtube and professional blogs outside of China's restrictive network."


- Shawn P, China

"Chameleon helped me access web resources I needed from my customer's network environment, which otherwise would have been inaccessible until I left for the day. Chameleon saved time and made me more productive."


- Kurt S, Japan

"Chameleon allows me to have my 256bit encryption that I have VyprVPN for, but also gives me the fantastic speeds that my 320mb broadband gives me. This has improved my browsing ten fold."


- Acey O, United Kingdom

VPN Blocking in China

China has one of the most censored internet experiences in the world, and since 2012 the country’s filtering mechanism, the Great Firewall of China, has been able to identify and throttle encrypted communication by recognizing packet data on the OpenVPN™ protocol. The Chinese government targets a variety of content, including Google products and social media and video/file sharing sites like Facebook, Twitter, YouTube, Vimeo and Wikileaks. While Chinese citizens and visitors to the country have historically used VPNs to circumvent the firewall and bypass this censorship, it’s becoming increasingly difficult. The government has become very efficient at identifying VPN protocols via DPI, which has led to more sites being blocked and web traffic being throttled.
