While VPN technology is complex, using a VPN all is just the opposite – without a few clicks, you can download a VPN app and enjoy the perks of having a virtual private network.
But we will not talk about the Why-s in this article. Instead, we’ll focus on How, and more specifically - which are the best VPN protocols and when to use them.
However, before we begin, we need to mention that each VPN protocol offered by PrivateVPN, has their utility. If it wasn’t the case, we would simply stop offering it to our customers.
|VPN protocol||Encryption Algorithm||Security Level||Speed Performance|
|OpenVPN||256-bit AES||Very high||Moderate|
Let’s go through the main VPN protocols and their advantages and disadvantages
The Point-to-Point Tunneling Protocol (PPTP) stands as a pioneering networking standard that seamlessly interweaves distinct Virtual Private Networks (VPNs). Conceived by the technological giant Microsoft, PPTP reigns as one of the earliest manifestations of VPN architectures, boasting a rich and storied lineage. But being one of the legacy protocols, it isn’t perfect.
The Layer Two Tunneling Protocol (L2TP) represents an advanced iteration of the Point-to-Point Tunneling Protocol (PPTP), devised to empower internet service providers (ISPs) in the deployment of robust virtual private networks (VPNs). To guarantee the utmost security and safeguard user privacy, L2TP necessitates the utilization of a sophisticated encryption protocol, ensuring the safe passage of data within the virtual tunnel.
Internet Key Exchange version 2 (IKEv2) is a sophisticated protocol designed to establish a secure connection, known as a security association (SA), between two network entities. Often used alongside IPSec, an authentication suite, this pairing is commonly referred to as IKEv2/IPSec by VPN providers. Developed by Microsoft and Cisco, IKEv2 is renowned for its enhanced stability, robust security, and efficient setup compared to alternative protocols.
OpenVPN stands as a dominant open-source encryption technology utilized extensively across the industry. Employing a top-tier security protocol, it leverages SSL/TLS for secure key exchanges, establishing protected point-to-point or site-to-site connections. OpenVPN operates over both User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) tunnel transports, ensuring web traffic remains virtually indistinguishable from conventional HTTPS over SSL traffic, and thus, exceptionally challenging to detect and block.
WireGuard represents an innovative open-source VPN protocol, utilizing cutting-edge cryptographic techniques to surpass the performance of established protocols such as IPsec and OpenVPN. Initially launched for the Linux kernel, WireGuard has since expanded its reach to become cross-platform and broadly applicable. Despite its ongoing development, WireGuard has already cemented its position as a highly secure, rapid, and user-friendly solution within the VPN technology space.
We’ve got plenty of experience delivering high-quality services, so labeling one as “the best” protocols is not the answer you would receive. Why? Because there are a variety of operating systems to run PrivateVPN on, and even more activities that you can do.
Let’s see the unique use cases and the best options for each of them.
That’s why, we advise you to pick one of the 3 options - OpenVPN in UDP mode, IKEv2, or WireGuard. While the latter shows great speed, it’s still questionable how reliable it is, so if you want to be “on the safe side”, then go with OpenVPN.
