What is a VPN?
A virtual Private Network or VPN is a connection service that makes it easier for you to access websites privately and more securely by hiding data exchanges that occur and changing connection paths through servers.
In simple terms, a VPN connects a PC, tablet, or smartphone to another computer or server that is connected to the internet. A VPN service, like iTop VPN, then allows you to surf the internet with a computer network. Thus, you can always be safer online.
If the server computer is in a different country, it will automatically be the country you will use to access the internet from the country where you are.
How VPN Works
Now that you know what a VPN is, it’s time for you to understand how it works. In accordance with the abbreviation of VPN, Virtual Private Network, encryption of data exchange is carried out before there is a public connection. So when connected to the internet, a VPN connection is like using a particular line and not through the main network.
The VPN server has the job of forwarding the connection to the site you want to access. So, the connection you make does not come from the network you are currently using. If you use a network without an India VPN, then the connection that occurs is without encryption.
A safe connection has become a standard that everyone should have when accessing the internet. All data involved in the process of exchanging data between you and the application can be seen by many people without any protection. This is not a problem if the data processing is only about Google search, entertainment, and the like.
However, suppose the data is personal and sensitive, such as business email and online banking. In that case, online attacks are more vulnerable if you do not use this private network.
If you use a Virtual Private Network, data encryption will occur first before being sent to the server. Thus, the server becomes the third device that connects to online services. This indeed ensures more security when data exchange occurs.
Functions or Uses of VPN
In general, the function of a VPN is to protect data when accessing the internet. However, there are several other functions, which are as follows:
1. Secure Encryption
To be able to read data, you certainly need an encryption key because, without it, the computer cannot decipher the data in the event of a brute-force attack. One of the functions of a VPN is to secure the encryption process so that all online activities can be hidden from public networks.
2. Disguise Location
The following function of a VPN is as a proxy on the internet. Demographic data from servers in other countries make the actual location disguised. Also, some VPN service providers won’t keep activity logs either.
Some services continue to record activity but do not provide information or data to any party. This allows each user’s data to remain secure and permanently hidden.
3. Transfer Data Safely
Most employees work from home during the pandemic but still need to access essential data using the company network. Therefore, the company will use a VPN to remain secure by connecting the service to a private server with an encryption method.
Try to find a VPN that’s compatible with all devices. That way, you can save more while enjoying the full services. Find the VPN for Mac, Windows, and smartphones that’s packed into one. That way, you can have better flexibility and functionalities.
4. Accessing Regional Content
Regional content, in general, you can’t always access from anywhere. There are specific sites that you can only access in certain countries.
But if you use a Virtual Private Network, then you can switch to a server in another country to access the site.
5. Reduce Connection Interference
A VPN service is a private network, so only you can use it. This dramatically minimizes interference from outside connections so that you are more comfortable and safe in accessing the internet.
If you want to be safer when going online, we definitely recommend using a VPN service. There’s a free and premium version of the service, so feel free to try which version.
