IPSec bundles these packets up and encrypts them, keeping them safe from snoopers and secure for transit. L2TP necessitates the use of the IPSec VPN protocol, seeing as it encapsulates data but doesn't offer any authentication itself. L2TP/IPSecĬomprised of Layer 2 Tunneling Protocol (L2TP) and Internet Protocol Security (IPSec), this VPN protocol is slower than PPTP, but far more secure, in large part because it offers industry-standard AES-256 encryption. In fact, PPTP has had security issues since 1998, and has been compromised by government agencies, including the NSA. Despite being relatively easy to configure, PPTP uses unsecure MS-CHAP-v1/v2 authentication protocols that offer little in the way of encryption (though they are quick).
So, which VPN protocol should you go with? Let's take a look at some of the most common contenders: PPTPĪlso known as "Point to Point Tunneling Protocol", PPTP was developed by Microsoft, released with Windows 95, and is known for its speed – and complete lack of security. The protocol that you choose, and its level of data encryption, will determine how secure your VPN tunnel is – but some are outdated, some offer speed over security, and others may not be compatible with your device. There are dozens of VPN encryption protocols available to use, and as you might expect, they're not all made equal. VPN - What are the differences between the two Picking a protocol – which tunnel is most secure? It'll go right through the tunnel from your device, before being routed through the VPN servers and onto the internet. In fact, nobody will be able to take a peek at (or monitor, alter, or otherwise meddle with) your data. Your ISP will see that you're sending and receiving data packets, but won't be able to view them, even if they intercept them!
Well, a VPN tunnel is an encrypted connection that links your device to the internet! This encryption keeps your personal information and browsing sessions safe from third-party snoopers – including your school or workplace, your ISP, or even your government. The security benefits of a VPN are plastered all over provider sites and lauded in reviews – but what exactly is this VPN tunnel that they talk about? What is a VPN tunnel? A VPN is also vital for anyone looking to connect to risky public Wi-Fi hotspots. You might need one to bypass strict censorship, or want to check out content from the other side of the pond. Nowadays, people use VPNs for all sorts of things.
