6 Different Types of VPN Protocols ExplainedSep 26, 2019 | 0 Votes by Justo - rate Learn more about how your VPN works by knowing more about the connection your VPN makes to its servers whenever you want to browse the internet!
A VPN (Virtual Private Network) is a tool that allows anyone on the internet to connect safely and privately. A VPN keeps your data safe because it creates an encrypted connection for all the information to go through.
There are two types of VPNs:
This one lets you access a private network and its contents from a remote location through a connection that takes place through the internet. It’s used by business people or home users alike.
AKA Router-to-Router VPN, this kind of VPN is the one that companies with multiple locations own because it creates a virtual connection between two points and connects all their terminals safely and privately.
Each type of VPN works with different VPN protocols. Each protocol has a different set of features and offers several levels of security. Here are some of them.
The 6 Different Types of VPN Protocols
"Wait a minute!", you may say... "I have no idea what VPN protocols are, let alone care that there are 6 different types of them!"
Well, to put it in layman terms, VPN protocol is basically the secret passageway that opens up, allowing you to leave your home whenever you like without letting the landlord know. It connects you, the VPN client, with the VPN servers which will, in turn, help obfuscate your traffic with millions of others. Couple that with encryption, this makes it impossible for your ISP, your government or any interested parties from spying on you as you browse the internet.
There are actually 6 "sneaky" ways a VPN can help you connect to their servers just so your ISP won't know.
Inner Protocol Security/IPSec
This protocol protects the IP network of end-to-end users. It improves the security offering the users the public/private keys to unlock/lock the data.
The Inner Protocol Security allows you to check on personal connections through an authentication scheme. Everything you send or receive divides itself into different packets, and each one has to pass an encryption process. So, this protocol has two modes: transfer mode and tunnel mode.
L2TP (Layer 2 Tunneling Protocol)
It’s a tunneling protocol which protects an entire network. This protocol is frequently combined with another protocol like IPSec to form a super secure VPN connection.
This protocol works through the exchange of data packets. If one user requests to establish a tunnel, L2TP creates a generation session as soon as data frames get ready to travel through a secure shell.
PPTP (Point-To-Point Tunneling Protocol)
It’s a combination of a PPP protocol with a Tunneling Protocol. It’s the most suitable protocol as it guarantees the security of the VPN. Microsoft is the company behind this protocol and it has been the most used one since Windows 95 was around.
SSL (Secure Socket Layer)
This protocol works on HTTP request. It allows the browser to work as the customer and not be restricted to the entire network, just a few of its uses. Online shops and service providers are the ones who usually use this protocol. SSL connections use “https” at the beginning of an URL instead of “http.”
This protocol is an open source VPN. Users find it useful to create Site-to-Site and Point-to-Point connections. It’s a customizable protocol that combines aspects of SSL and TLS protocols.
SHH (Secure Shell)
It creates a secure tunnel and encrypted tunnel that allows the data to travel through it. This protocol operates in a way that makes possible the protection of the communication between two points (the client and the server).
Now that you’re familiar with the types of VPN and their protocols, it’s up to you to choose the best option to adapt to your needs according to what you’ll be doing online. The important thing is to stay safe and always protect your connections in the best way possible.
