A VPN is simply an encrypted connection between two computers, each side running VPN software. The two sides, however, are not equal. The software that you, as the user of a VPN service deal with, is known as the VPN client. The software run by a VPN company is a VPN server. The encrypted connection always starts with a VPN client making a request to a VPN server.

There are many different flavors of VPN connections, each with its own corresponding client and server software. The most popular flavors are probably L2TP/IPsec, OpenVPN, IKEv2 and PPTP. [ Related: ] Some VPN providers support only one flavor, others are much more flexible., for example, supports OpenWeb, OpenVPN, PPTP, L2TP, Cisco IPSec, IKEv2, SSTP, StealthVPN and RouterPro VPN. At the other extreme,, as their name implies, only supports OpenVPN. I mention this to counter some mis-leading information from normally trustworthy sources.

[ ] The fact is, VPNs can be used without installing software. And, a case can be made, that this is the safer way to go. BUILT-IN VPN SOFTWARE To avoid installing software, the operating system on the computer/device that is the VPN client has to natively support the same VPN flavor(s) offered by a VPN provider. As my recent blog,, showed, Chrome OS, the operating system on a Chromebook, natively supports L2TP/IPsec and OpenVPN.

IOS version 10 supports IKEv2, IPsec and L2TP. You can see this with Settings -> VPN -> Add VPN Configuration -> Type. IOS 9 supported these three plus PPTP, but in version 10. Android version 6 supports PPTP, L2TP/IPSec PSK, L2TP/IPSec RSA, IPSec Xauth PSK, IPSec Xauth RSA and IPSec Hybrid RSA. You can see this with Settings -> More -> VPN -> Plus sign -> Type.

OS X 10.11 El Capitan PPTP, L2TP, IPSec and IKEv2. The previous version, 10.10 Yosemite,. Jvm for mac vs windows. The latest version, macOS Sierra 10.12, for PPTP. Configuring a VPN on Sierra does not have to be hard.

These instructions from Apple,, talk about using a VPN settings file to automatically import VPN settings that configure the built-in VPN client software. Windows 7 and Windows 10 PPTP, L2TP/IPSec, SSTP and IKEv2. Both ExpressVPN and NordVPN give their customers a (.pbk) for use with the VPN client software built into Windows. The file is pre-configured to work with the multiple VPN servers each company supports. NordVPN describes this in their instructions. ExpressVPN refers to the file as a Windows Dialer file and describes its use.

OPEN SOURCE And, there's another option. Open source client software is available for OpenVPN and IKEv2 based VPNs (not sure about other VPN flavors). With this option, you can use software that has, hopefully, been audited or vetted. OpenVPN provider, they let their customers use either Mullvad-provided software or an open source alternative.

Open source software is not always an option though, some VPN providers, such as and F-Secure, require customers to use their software. NordVPN Windows VPN client options The page (above) shows that they support all three types of VPN software on Windows. With Windows 7, 8 and 10, they offer six ways to connect to their VPN service. 'Application' uses software provided by NordVPN, 'OpenVPN' uses software downloaded from openvpn.org. The other four options (L2TP/IPSec, PPTP, IKEv2/IPSec and SSTP) use no external software, they merely configure Windows to use VPN client software that is built into the system. To a Windows VPN user, this total flexibility is as good at it gets.
