VyprVPN offers “Chameleon” stealth technology specifically designed to help defeat the GFW, and the fact it has complete control over its own network means that VyprVPN is great for security. Its servers located in Hong Kong, South Korea, and Japan are also conveniently located for anyone in mainland China. VyprVPN’s desktop client for Windows and MacOSX is nifty, and features firewall-based DNS leak protection and kill switch. As with ExpressVPN, VyprVPN adds value to its package by throwing in a free Smart DNS service.
Additional features: no usage logs, free SmartDNS, DNS leak protection, kill switch.
