![]() Remember not to confuse the encryption levels of the control and data channels, they are separate issues. The data channel is the encryption used in the secure VPN tunnel encrypting the data between your system and the VPN server, this is your fluffy youtube cat videos, your emails and whatever else you get up to on the internet.Īs mentioned earlier encryption can affect speed which is why you’ll often see high encryption for the authentication and lower for the encryption of the actual data passing through. Authentication is the point where your VPN provider checks your login and password details to ensure that your account is valid, you are who you say you are. In terms of Encryption, there are two critical areas to consider.įirst is the encryption used for authentication also known as the control channel. PPTP is not recommended so unless you’re just using a VPN to bypass a geo-block then avoid it when possible. OpenVPN is the recommended standard, however if this isn’t available on the device you’re using then aim to use either L2TP or SSTP. The different types of Encryptionįirstly there are four main types of VPN standard, these include PPTP, L2TP/IPSec, OpenVPN and the lesser popular SSTP. If those low encryption providers increased their encryption levels they know themselves their network would grind to a halt for their users and so they continue to sell the lower encryption as a “bonus feature” giving you better speeds when in reality these can still be achieved with higher encryption at least on a desktop system from a good VPN provider.Įncryption is a critical consideration factor. Often those that offer lesser encryption have a worse, oversold network and so speeds are only comparable or lower than those that offer higher encryption. ![]() ![]() ![]() In my years of VPN use and writing I’ve noticed that providers who offer lower encryption often state the payoff for higher encryption is speed and while this in theory is true it doesn’t always factor when comparing VPN providers. While some public VPN providers offer high levels of encryption others offer the lower end of the scale and the situation becomes even more confusing when advertising slogans refer to data encryption but fail to mention the encryption used for authentication (handshaking) or vice versa. There is just so much choice out there and every provider appears to be offering different standards. If you’re new to the world of VPNs or even if you’ve been around them for a while keeping up with the best encryption method is a tricky task. ![]()
