What are VPN Protocols and Where to Use Them?

Before diving deep into the world of VPN Protocols, let’s understand what a Virtual Private Network or VPN is. It’s an innovative technology that allows internet users to mask outgoing and incoming traffic on multiple network channels. In short, a VPN safeguards your digital footprints from unethical usage.

When it comes to establishing an internet connection that involves a Wi-Fi hotspot in a public place, VPN protocols are a necessity. VPN protocols allow users to securely browse the internet without worrying about harmful third parties. With the help of data encryption, a VPN protects your information. It makes sure that the outbound or inbound traffic from your computer or other devices does not get compromised. Your information is secured in the best way possible. No one can intercept and use your data for their benefit.

 

VPN Protocol: What It Is

VPN Protocols are comprehensive services that establish a secure connection between the internet and other devices. Typically, it’s a setting to encode users’ data when interacting with several web servers to and fro. Equipped with multiple settings, VPN protocols are effective irrespective of the extent of cyberattacks.

The IKEv2, for example, is perfect for stationary tech. Whereas, portable devices can use other protocols as suited. For a normal internet user to understand what VPN protocols are, it is important to know what they provide. Simply put, VPN protocols are the technology that drives Virtual Private Networks. A VPN protocol determines the routes that guarantee safe inbound and outgoing traffic. However, it depends on what device you are using and your location.

To get the most out of VPN capabilities, ensure that you are using the right VPN tools. This is the only way to secure our data when browsing through sites. When you are using a PC or a laptop to browse the internet, use the right VPN plugin. When you are using a smartphone, ensure that you have the VPN app installed for either Android or iOS devices.

VPN Encryption: What It Is

VPN encryption is another innovative technology that uses data encryption to protect your online identity. The VPN encryption converts easily accessible and readable formats into encrypted codes. Data encryption makes the incoming and outgoing information inaccessible to third parties. Decrypting your data is possible only by using the appropriate keys. Because of data encryption technology, users’ online activities stay hidden from harmful third parties and internet service providers. Using VPN encryption is a necessity when you are on the web. Especially, when connecting to the internet via public Wi-Fi hotspots. This is when your data are unsafe.

So, what happens when you are using the internet via an unsecured public Wi-Fi and do not use a VPN? Harmful third parties can trace your location and get the information they need. Not only does your data get compromised, but also malicious software can destroy your computer.

Planet VPN: What Protocols Do They Use?

A trustworthy VPN provider like Planet VPN allows its users to browse the internet securely. Additionally, Planet VPN allows its users to use the web without geographical limitations. Users do not experience slow traffic speeds. Planet VPN even bypasses restrictions set by internet service providers. This allows users to browse content online without any restrictions.

Planet VPN offers:

• PPTP (Point-to-Point Tunneling Protocol) – The so-called P2P tunneling protocol enables a secure internet connection between the server and the computer.

• L2TP/IPSec (Layer 2 Tunneling Protocol/Internet Protocol Security) – The second layer tunneling protocol has encapsulation that makes the applications interact for some time as needed.
• OpenVPN – It’s a VPN protocol responsible for providing secure communications between users over a network.

• IKEv2 (Internet Key Exchange) – This VPN protocol allows users to communicate over a network.

Using VPN Protocols the Right Way:

Every VPN protocol has separate algorithms needed to encode information. Although it impacts the overall processing speed of requests made, it ensures maximum security within the network. It depends on individual needs when it comes to choosing the right VPN protocol.

Here is an overview of the different types of VPN protocols.

1. PPTP

No wonder, PPTP is the most common choice among users. A user can use this protocol when sending data from their computer or other devices via a VPN channel. However, a password authenticates the devices.

Benefits – PPTP works conveniently for users. That’s because the formation of a secret key does not require buying extra equipment. PPTP is the simplest protocol that performs great in almost every online environment. Besides, installing PPTP does not require additional skills. Even non-professionals can install it with ease.

Downsides – PPTP is considered a weak encryption protocol. The transmitted key even has weak protection. Hence, it is not suitable for users that share confidential data.

2. L2TP/IPSec

RTR protocol and L2TP/IPSec have similar features. But the difference lies in ensuring maximum data privacy. In that case, L2TP/IPSec has an upper hand over the RTR protocol. L2TP/IPSec uses dual encapsulation. L2TP does not encrypt data. Rather, it transfers data. IPSec protocols, on the other hand, provide tunneling. That’s why they are named L2TP/IPSec.

Benefits – Protocol support for L2TP/IPSec comes bundled with every operating system. Therefore, users can configure this protocol on their mobile and other devices. All they need is Windows, Linux, Android, or iOS software.

Downsides – L2TP/IPSec protocol has reduced network connection speed. The protocol uses encapsulation for enhanced security.

3. OpenVPN

Although OpenVPN is not a pure protocol, it’s an open-source solution that provides quick data transfer while authenticating your device. OpenVPN creates a connection with encrypted data to the internet. When it comes to exchanging encrypted information, OpenVPN uses TCP and UDP transfer protocols. However, using either of these transfer protocols depends on two factors: high speeds or a secured connection.

Using TCP transfer protocol results in confirmation of receipt for every packet sent instantly. If the connection is unstable or the chances of traffic blockages increase, the TCP protocol comes in handy. Using the UDP transfer protocol results in faster data exchange. Whether it is verifying lots of data packet transfers or comparing the received and transmitted data packets, everything happens in the last step. When the internet connections are fast, the UDP transfer protocol is the best option to choose.

Benefits – Because of the open-source code, OpenVPN uses non-standard encryption and transmission settings. Even special services cannot decode the encryption. OpenVPN provides security of the highest level and delivers sheer performance. Many experts believe that OpenVPN is the best option to create a virtual private network.

Downsides – The installation process of OpenVPN is quite complex like other protocols. It requires 3^rd party software because no operating system supports OpenVPN.

4. IKEv2

Developed by Microsoft and Cisco, the IKEv2 is considered a modern-day VPN protocol. It can create direct tunnels between the server and the client. It uses classified IPs for this purpose. You can make good use of cryptographic algorithms by using this VPN protocol. The user can choose a convenient method to encrypt information. Moreover, the IKEv2 protocol protects against potential DoS attacks. Apart from that, installing IKEv2 on a variety of devices and routers is a breeze.

Benefits – When it comes to fast data transfer, the IKEv2 protocol is the best option. This is because the IKEv2 protocol operates on the kernel level of an operating system. The best part is that IKEv2 works fine with low-performance systems. Also, it works great with mobile devices and computers with low resources.

Downsides – Not every operating system supports the IKEv2 VPN protocol.

VPN Protocols Comparison: Which Option Is Best Suited for Your Needs

There is no shortage of VPN protocols. Hence, it is important to find out which protocol best suits your needs. Every VPN protocol offers different levels of security and unique features. Let’s discuss them in detail.

• L2TP/IPSec – The L2TP along with IPSec is the best option for users who are looking for an easy-to-use VPN protocol. The L2TP/IPSec protocol provides users with strong encryption. However, OpenVPN offers more secure encryption than the L2TP/IPSec.
• IKEv2/IPSec – In this type of VPN protocol, you can have reliability and speed. It is a good option for use on mobile devices. This protocol reconnects to the server quickly even after switching a network. You can have a consistent connection when using the IKEv2/IPSec protocol.

• SSTP – Introduced by Microsoft, the SSTP protocol is a great option for people using Windows. Because of the SSL/TLS encryption, this protocol is highly secure. However, SSTP might come with restrictions for platforms not running on Windows.
• PPTP – Although fast, PPTP comes with fewer security features. PPTP is a suitable option for users who want fast internet even if it comes with low security. Users should avoid sensitive activities when using this protocol.
• WireGuard – It’s a new VPN protocol that has been gaining popularity more recently. WireGuard offers efficiency and strong data encryption.
• IKEv1 – The IKEv1 protocol has less security than IKEv2. Certain VPN services offer IKEv1 protocol.

Choosing the best VPN protocol for your needs depends on certain factors. These might include ease of use, speed, security, and compatibility. It is recommended to opt for a VPN service provider that offers several VPN protocol options. This allows you to switch options whenever a situation arises. Choose a reliable VPN service provider for a satisfying and secure experience on the internet.
