A VPN is touted as a solution to be able to browse the internet securely so that personal data is also protected. To be sure, networks that rely on privacy services are a breath of fresh air amid rampant online data theft.

So, is it true that using a private network is the best solution for protecting personal data on the Internet? Let’s find out what a VPN is, why it is used and how it works with the following review.

Learn what a VPN is

In short, a VPN is a software that allows its users to connect to the Internet service privately. A VPN is said to be able to provide secure access through a server connection by hiding traces of the user’s personal data.

VPN connection service gives you as a user to access websites securely, securely, privately or privately by changing the connection path to the server and masking the data exchange.

In simple terms, a VPN will connect smartphones, tablets, and computers with other computers connected to the internet. In this way, you can surf the Internet using your computer’s Internet network.

By using a computer or server from a different country, you can access something that is not accessible in your country. Using another country’s server, it becomes the server of the country used when browsing the Internet.

VPN functions for daily activities

VPNs have their own different functions and uses. Especially those that are said to protect personal data. In addition, its use can also close access to the history or digital traces of its users.

Therefore, no one else can access the history or history of other users. Using a VPN also allows you to break free from internet data usage restrictions. Other functions of using a VPN are as follows:

1. Hide browsing activity
The functionality that its users raise the most is as a means of privacy when browsing and accessing important content that others should not see. A VPN can help you mask and mask your internet activity.

2. Allow access to restricted websites
Another function is that it can be used to help users access blocked and censored websites or websites. In fact, this function has a negative effect and is often abused by some people.

Many users use VPN as a tool to unlock dangerous sites like gambling sites and porn sites that have been blocked by the government in Indonesia. Therefore, the effect is due to the consciousness of its users.

3. Secure online transactions
VPNs are known to have an impact on business activities such as online transactions. Because it can come in handy when the people who own this business are doing online transactions over the internet.

A VPN is a feature that must be activated when you are out of town and using public internet access such as WiFi or Internet cafes. Data theft often occurs when we use public internet resources.

So, to avoid bad things like account card numbers being stolen etc, you need to activate the VPN feature while using the public internet.

4. Increase download speed
Sometimes some files on the Internet have a very large size. This of course affects the speed capacity when you want to download it. The internet usually has a speed limit.

To increase the internet speed, a VPN is required. Because one of the functions of a VPN is to increase your internet speed while downloading files.

How does a VPN work

When you use a VPN, the network will encrypt data exchange even before public connections, such as coffee shops or other places that provide free internet access, read the data.

When you connect to the internet with a VPN, it’s like accessing the internet using a private tunnel, not using the main network directly. Later, the VPN server is responsible for redirecting the connection to the site to be accessed.

Thus, the connection you are using as a connection is recognized as the VPN server network and not the network in use at that time. It’s different if you access the internet without using a VPN. Therefore, the connection made will be live without encryption.

Unencrypted connections have already become the norm when browsing the Internet. All data will be shared in the process of exchange between you and applications on the Internet, so that it can be seen by as many people as possible.

If it’s just a Google search or access to entertainment or the like, it won’t be a big deal. What will be a problem is when the data being processed is online banking, business email, or other more sensitive matters.

When you use it, the data will be encrypted by the app first, then sent through your ISP and then to the VPN server. The server becomes a third device to help connect you to online sites.

Using a VPN, secure or not?

Security when using this server network service has become a topic of great debate among IT employees and companies. Using a VPN makes your network connection more secure, but it still depends on the protocol you’re using.

Security in the use of this service continues to be hampered by legal and technological restrictions. Legal policies affect what can be done with a VPN.

So policies can sometimes affect how companies apply VPN technology to their services. So it can be said that using this server is not completely secure, but it is still more secure than using the connection in general.

Likewise for the technical limitations that have limits to developing VPNs, such as developing the type of protocol and encryption that will be used.

When do you use a VPN server?

The above explanation will definitely make you confused when using a VPN to stay secure and avoid data theft by hackers.
You can use it when you want to do some activities as below:

* While using a public WiFi connection.
* When you want to hide an activity from people who want to try to know more about you secretly.
* When you want to hide your location and want permission when accessing geo-blocked content (content blocked by geo-region).
* When going to surf the Internet anonymously on a website.
* When you want to encrypt your activity while browsing the Internet.
Using a free or paid VPN?

Today, there are many VPN services that provide servers for free, which means that their users can use the service without having to pay a single penny.

But what you need to know, using a VPN, especially the free ones, can make your personal data registered by the VPN service provider every time there is activity, and unfortunately many free VPN service providers are not responsible for this action.

Even worse, your personal data can be sold, seized, or used for criminal purposes.

The downsides to using a free VPN are dire, aren’t they?

But don’t worry because there are quite a few VPN options now. One such example is NordVPN which you can get at a low price.

On the other hand, paid VPNs also provide maximum security to their users. It can automatically block websites that are flagged as suspicious and can block annoying ads.
