VPN:With the growth of the Internet, online data theft is also increasing. From your personal data to bank accounts, anything can be stolen if you don’t protect it properly when you make online transactions.
What is a VPN? Why do we need a VPN?
In order to protect your data, you should use any medium that helps you protect your data. One of these supports is the VPN (virtual private network). By using a VPN , your data is encrypted and no one can steal it.
Besides data theft, the VPN also has many other features. Let us discuss in more detail on What is a VPN, How to Use a VPN, Benefits of Using a VPN and much more in this article.
What is a VPN?
VPN stands for virtual private network. A VPN allows you to establish a secure connection with another network. It also increases the security of private and public network connections. A VPN masks your IP address and displays a different IP address for the others.
Each time you transmit data to another network, VPN encrypts it and sends it as encrypted data to the network.
To be more precise, a VPN adds security and confidentiality to its customers. The virtual private network also allows you to remove geographic barriers. Blocked location-based content is accessible through a VPN.
How does a VPN work?
Once connected to a VPN server, the software starts encrypting the data before your ISP takes note. Then the data is encrypted and transmitted to the VPN. From the VPN server , the data will reach the destination network. The network can now only see the IP address and location of your VPN server. Your personal IP address and location are hidden using a VPN.
If you are not using a VPN network, there is a risk of data theft. If you use a VPN, your data will enter the encrypted network that protects your data.
Here are the steps on How a VPN works:
# 1: You must first install and activate the VPN on your device. (The device can be any medium used to connect to the Internet. For example: mobile phones, computers, iPad, USB Fire Fire key, Android TV, etc.).
# 2: After activation, VPN will start encrypting your device data. (Once the VPN is activated, your IP address is hidden and you are not connected to a virtual IP address).
# 3: Now everything you search for or give as input will go as encrypted data.
# 4: The encrypted data will be transferred to the VPN server and from there it will be sent to the destination online. (By checking your IP address, the online destination website or network will only find the IP address and location of the VPN server).
Your location and IP address will remain hidden using a VPN server. Here is the step-by-step procedure on how a VPN works.
Benefits of using a VPN
Using a VPN has many advantages. Here are the most important advantages of using a VPN:
- VPN hides your IP address and location.
- The data and communications put online can be encrypted.
- Using a VPN, you can view all blocked websites from anywhere.
- Your device is protected from surveillance. No one will be able to watch or monitor your activities on your device.
- The data is completely encrypted and you can hackers and thieves will not be able to steal your password or other data.
- VPN also prevents third parties who track your data.
- By connecting to a broadband VPN, you can access movies and videos in 4K resolution without any sort of buffering.
- Videos that are not available in a specific country can also be viewed using a VPN.
These are the most important benefits of using a VPN.
For any application, a protocol can be followed to guarantee the standards. Likewise, VPN also has different protocols and all reputable VPN companies follow any of the protocols to maintain their standards in the VPN industry. Here are the most commonly used VPN protocols:
# 1: PPTP : PPTP is a point-to-point tunneling protocol. It is one of the oldest protocols used. This protocol is now barely secure. The protocol was developed by Microsoft and is very easy to install on older computers. Do not choose the VPN which only follows the PPTP protocol.
# 2: L2TP / IPsec : this protocol was the combination of PPTP and the Cisco L2F protocol. The L2TP protocol used keys to create a secure connection at each end of the tunnel, but the execution of this protocol is not very secure. To improve security, IPSec has been implemented with L2TP. However, there is a debate that hackers have the ability to break this protocol and therefore it is best to avoid it as well.
# 3: SSTP : SSTP is a secure tunneling protocol. This is another protocol built by Microsoft. It uses SSL / TLS encryption to establish the connection. The SSTP protocol is one of the most secure solutions used.
# 4: IKEv2 (Internet Key Exchange, version 2) : another Microsoft protocol reinforcing security compared to the previous version. IKEv2 is the iteration of the Microsoft protocol that was previously developed. This protocol is one of the best security solutions for your data.
# 5: OpenVPN : the OpenVPN protocol makes the most of all the other protocols used previously. It is an open source protocol that works with SSL / TLS. As an open source protocol, it is constantly being developed by many developers around the world. OpenVPN is the best VPN protocol available on the market.
If you are considering purchasing a VPN service, you can check the protocol version and continue if the VPN offers the OpenVPN or IKEv2 protocols.
Free and paid VPN
Both will provide the same service but the quality will certainly be different. If you really want to opt for a world class VPN service, you need to purchase only the paid version. Here is the important difference to understand between free and paid VPN:
# 1: Speed: You can’t expect to download and download from a free version. If you’re using a paid VPN, you have the right to ask questions when you can’t expect speed with a free version.
# 2: Limited IP addresses: a free version will only offer a few IP addresses and everyone will use the same thing. In paid VPN mode, you have access to many IP addresses around the world.
# 3: Ads: A free VPN will surely show lots of ads on their app, because it’s the only way to win. The paid version will not display any ads.
# 4 : Security: a free version can track your information and sell it to third-party apps to make money. This is one of the major drawbacks of using free VPN.
This is the main drawback of using a free VPN. The only positive is that the free VPN is available for ” Free “.
How much does a VPN cost?
