Using an outdated VPN protocol could potentially put your online data and experience at risk. Usually, you’ll need to go into the settings of your VPN app to change protocols.īeing aware of these different protocols is important because they often determine the overall speed, security, and privacy of your VPN service. So, if there’s one you prefer, you can use that as your main VPN protocol. However, what you'll find is that many VPN services allow users to switch between different protocols. NordVPN believes every protocol is imperfect, explaining that “each may have potential vulnerabilities, documented or yet to be discovered, that may or may not compromise your security”.Īt their core, most VPN providers currently use the OpenVPN and WireGuard protocols, which are highly secure and generally very fast. There are lots of VPN protocols out there, but the most common are Secure Sockets Layer (SSL), Transport Layer Security (TLS), Point-to-Point Tunneling Protocol (PPTP), IP Security (IPSec), Internet Key Exchange (IKEv1 or IKEv2), Layer 2 Tunneling Protocol (L2TP), WireGuard, and OpenVPN.īut with VPN services constantly evolving, protocols quickly become outdated and new ones enter the industry. NordVPN says every protocol provides a “different solution to the problem of secure, private, and somewhat anonymous internet communication”. So, what are they? VPN protocols are essentially commands and processes that decide how web traffic travels from one server to another within an encrypted tunnel. In addition to encryption, another fundamental part of VPNs is their protocols. Visiting Japan? You'll need a Japan VPN.The vast majority of VPN services use one of the most robust encryption methods available, AES-256. While the VPN encryption process may seem long and complicated, Surfshark points out that every step “happens in a second” – and sometimes “in a fraction of a second” if you have a fast internet connection. Lastly, the VPN service deciphers this data before sending it to your device.Īt every step of this process, your data is encrypted and decrypted. ![]() At this point, the VPN server would re-encrypt and dispatch it to your VPN service. The email server would then get the request, grant it, and return this data to your VPN server. Once the VPN server has received this request, it’d send the data to your email provider’s server, still encrypted. After establishing a connection between your device and a VPN server, the VPN service would send your login request to the VPN server via an encrypted tunnel. How does this work in practical terms? Well, if you tried logging into your email account, this request would be communicated to the VPN service. Using encryption technologies, VPNs ensure that credit card numbers, passwords, messages, transaction history, browsing data, and other sensitive information travels through an encrypted tunnel in undecipherable code. One of the most important functions of VPNs is their ability to encrypt personal data and web traffic. So, in short, a VPN redirects and encrypts your internet traffic, making it effectively invisible to anyone on the outside – including your ISP. VPN services typically provide servers worldwide, and by connecting to a global network of servers, you can spoof your location to bypass geo-restrictions and unblock online content that would normally only be available in a specific country. However, something to bear in mind is that VPNs aren’t just helpful security and privacy tools. Therefore cybercriminals, government agencies, internet service providers, companies, and other third parties can’t intercept your personal data, track your online movements, or see where you’re located in the world. What’s more, a VPN server will hide your internet protocol (IP) address. In this tunnel, web traffic sent to and from your computer will be encrypted at all times. This effectively routes your traffic away from your ISP’s servers and through its own. ![]() In simple terms, a VPN is a software-based tool that provides an end-to-end encrypted tunnel between your connected devices and a VPN server. or if you use Apple, the best Mac VPNĪlthough there are lots of VPN services on the market, they all work in much the same way.
