PPTP
PPTP is a fast, & easy-to-use protocol with a simple setup process. It is a good choice if OpenVPN isn’t supported by your device.
OpenVPN ™
OpenVPN is the recommended protocol for desktops including Windows, Mac OS X and Linux. Highest performance – fast, secure and reliable.
L2TP/IPsec
L2TP/IPsec is a protocol built into most desktop, phone, and tablet devices. It is a good choice if OpenVPN isn’t supported by your device and security is top priority.
Chameleon ™
Golden Frog’s proprietary 256-bit SSL protocol masks VPN traffic so it cannot be identified as a VPN connection and blocked, while retaining speed and security.
NAT Firewall
NAT Firewall is not a VPN protocol, but a packet filter that blocks unrequested inbound traffic from reaching your device when using VyprVPN. Hackers and botnets scan the Internet for unprotected devices so they can steal your credit card numbers, passwords, sensitive financial and personal data, or install malware. NAT Firewall blocks them from accessing your computer, mobile device or tablet.
