The Types of VPN Protocols and Their Advantages/Disadvantages

Types of VPN Protocols

Types of VPN Protocols

A VPN which stands for Virtual Private Network is a network that you can access remotely. This means that you are able to connect with another network through your internet service provider’s connection which then allows you to browse the web as if it were from that location. There are many different types of VPN protocols that have their own pros and cons. Here we will discuss what they are and how they work!

CyberRouting Offers 1-click-setup VPN for Mac, Windows, iOS, and Android. Access the internet from anywhere, whether you’re on a computer, smartphone, or tablet. Auto-configuration is supported for all major platforms* allowing you to surf unrestricted with no coding or complex setup required. Simply download and connect. Setup a VPN Now.

Different Types of VPN Protocols:

  1. PPTP (Point to Point Tunneling Protocol)– It is a basic form of security that allows you to access private networks through the internet. It can be used by different operating systems such as Windows, Mac OS X and Linux. What makes it secure is its 128 bit encryption, which has been considered not safe enough in recent years due to huge advances in cyber technology. So we advise using this protocol only if your device doesn’t support any other ones or for short connection needs since it’s a very fast way to establish a VPN network between two devices!
  2. LCP (Layer Control Protocol)- This one comes with PPP package and manages data transmission over the tunnel created by PPTP like transmitting session IDs, acceptance or termination of a tunnel etc. What’s great about this protocol is that it can negotiate different authentication methods with other devices on the network you’re trying to connect to!
  3. LSP (Layer Switching Protocol)- It comes as part of the Layer Two Tunneling Protocol and allows for creating VPN connections between two devices through several intermediate networking protocols like IPX, Apple Talk etc. This option is very useful if your device doesn’t support any other ones but should be used only when necessary since its encryption level isn’t high enough compared to PPP/LCP/MSCHAPv15 options.
  4. IPSec (Internet Protocol Security)- What’s great about this protocol is that it provides the highest level of security among all protocols in our list by using strong cryptographic algorithms like SHA, AES and RSA. It can be used for different operating systems but its biggest drawback is speed since data packets are large which affects performance when transferring them over long distances or between devices with low processing power under their hoods.
  5. LSP/SSL (Layer Switching Protocol / Secure Socket Layer)- is an advanced version of SSL VPN created to use stronger authentication methods than standard ones available with LDP/SSL package! What makes it unique compared to other options available here? Well, you’ll need a server certificate installed on your device before being able to establish a VPN connection with it! What’s more, LSP/SSL is considered to be faster than IPSec in terms of performance and encryption level.

2. How to choose a VPN protocol

VPN protocols are the technology that comes into play to encrypt your data connection between you and a VPN endpoint. There are many different types of VPN protocol, each with their own pros and cons. Here’s how to choose one when installing a VPN app on iPhone or iPad:

Many people have heard about OpenVPN but not much more than its name. This is because it has been around for so long without being updated very often, which means there are no real high-level technological developments in recent years – only incremental updates here and there to fix bugs etc. It was originally released way back in 2001 under GPLv0 license (and free) which meant anyone could use it in commercial products as well as study the code and contribute to its development.

OpenVPN is currently at version two of the software, which comes with a number of benefits:

– It’s open source – Anyone can view the code and submit changes for review by developers (this does not mean they will be accepted)

– There are many different client apps that support it on mobile devices such as iOS or Android phones/tablets etc. You may need to pay extra for an app but some VPN services include this in their subscription fee already so you won’t have to spend any money out of pocket if you use one regularly.

– Other operating systems like Windows support OpenVPN

– Open source means it is constantly being updated to fix bugs and improve performance. This does not mean the code will always be free, as there have been cases where a developer has released open-source code but then started charging for it later on. There are also many VPN providers that use their own version of open VPN which they don’t share with anyone else – this can cause problems because you cannot know if a company isn’t keeping something shady from its customers by hiding back doors in its software somewhere.

– To ensure your traffic cannot be intercepted by third parties, OpenVPN uses the same encryption standards like SSL/TLS which are used for secure connections to websites. It also supports multiple ciphers and has an ‘HMAC firewall’ feature that blocks all suspicious packets instantly for maximum security. The only downside here is that iOS doesn’t support AES 256-bit – but this can easily be fixed with apps like CyberRouting VPN, which have custom clients on iOS so you don’t need any jailbreak tweaks. These will allow you to specify a port along with other advanced configuration options not available in most other apps if needed.

– It has a ‘network lock’ feature that prevents your IP address from leaking in the case of sudden disconnection – this is also known as an ‘implicit kill switch’. If you are using another protocol then when the VPN connection drops out for any reason, all traffic will be routed directly through your ISP without encryption. This means anyone that manages to intercept it can read everything being sent.

So now we’ve covered some basics on how OpenVPN works, let’s look at why alternative protocols may be better for specific applications:

IKEv (Internet Key Exchange version) is an alternative VPN protocol for establishing secure connections on IP networks. It was initially developed by Microsoft but has since become a standard across most platforms including iOS and Android. The only downside of IKEv vs OpenVPN is that it lacks ‘Network Lock’ which means your IP address may leak if the connection unexpectedly drops out of the blue, so this should never be used when privacy or anonymity are key concerns (but can offer improved speeds in some scenarios).

IKEv uses UDP port 500 whereas OpenVPN uses TCP/UDP port 11948, both have their own pros & cons.

– SSTP is another alternative VPN protocol that uses the Secure Socket Tunneling Protocol. This can be used with traditional computers but also mobile devices running Android OS version above version KitKat (so anything newer than Jellybean). It’s not open source so no one knows exactly how it works inside, but what we do know is that Windows has been using SSL/TLS certificates to secure traffic since Vista SP  (which means there are backdoors in every single version of this OS which cannot be controlled by users), and they have confirmed these keys are accessible to third parties like the NSA. The whole point of a VPN service is that nobody else apart from yourself should ever know your real IP address – using SSTP defeats this purpose entirely.

– PPTP (Point to Point Tunnelling Protocol) is the last alternative VPN protocol that I’m going to mention here, and it’s another old one originally developed by Microsoft. It does not provide any encryption on its own so all data sent over a PPTP connection can be intercepted if you are connected via an untrusted network like at your local Starbucks or airport for example. To make matters worse, there have been numerous security vulnerabilities discovered in the past with this protocol which makes it even less secure than Look’o ‘N Go Wifi!   For these reasons alone, never choose PPTP when given the option of other protocols.
