What is a VPN?

Virtual Private Network is a type of technology that offers personal and secure access to the internet. It encrypts and routes your internet connection through a distant server, making it more difficult for others to intercept or access your online activity. It makes it an essential tool for people who want to protect their privacy and security online.

One of the most important benefits of using a VPN is that it protects your online privacy and security. Your data is encrypted when you connect to the internet using a VPN, making it far more difficult for hackers, government agencies, or other third parties to intercept or access your online activity. It can be imperative when using public wifi networks, which are often unsecured and vulnerable to hacking.

This is a tunnel for internet activity where anyone can’t trace you. Only you will know what files you shared, what products you bought while shopping, and what you did on the internet using VPNs.

What are the Benefits of Using a VPN?

As we mentioned, VPNs encrypt your internet connection, so your online activity and data will be completely safe. Some are other benefits you can get while using VPNs.

  1. Protecting online privacy and security: helps to hide your online activities and protect your personal information from being monitored or stolen by hackers or government agencies.
  2. Accessing restricted content: help you bypass geographical restrictions and access content unavailable in your country, such as streaming services or websites.
  3. Enhancing online security: help secure your internet connection using public wifi networks and protect you from hacking or identity theft.
  4. Maintaining anonymity online: help you stay anonymous by hiding your IP address and making it difficult for others to track your online activities.
  5. Improving network performance: improve your network performance by reducing lag and improving download speeds when accessing content from remote servers.

What are the Limitations of VPN?

If there are benefits of VPNs, there are also some limitations of VPNs.

1. VPNs Blocks

If a business or company knows about a server with a VPNs IP address, then they can block your IP address from getting access to their content.

You don’t need to worry because your server can turn on a new IP address with the help of a VPNs to access the content again.

2. Slow internet speed

In most cases, when you use VPNs services to access content on the internet, then your internet speed will automatically slow down.

It happens because your server goes through more processes when it is connected to VPNs. So VPNs developers frequently work to optimize speed and performance to provide users a better experience than before.

3. Saves your online activity

You know VPNs protect your data from hackers, governments, and other third-party users, but do you know that some VPNs providers can see your online activity?

Yes, you might be shocked after knowing this, which is a true thing. So you have to choose the best VPNs service which doesn’t track your online activities.

4. No QoS

Basically, QoS means the quality of service you get while using VPNs services. You will not get any metrics data to analyze the working of the VPNs over your network.

So you can take a look at the reviews mentioned by previous users about a particular VPNs service.

5. Unsecured Cookies

As we know, VPNs protects our online activity and keep our network encrypted but you may get cookies on your browser while using the websites.

Most websites save tracking cookies on your browser so your location can be easily found by the website server.

You can delete these tracking cookies easily but this may be time-consuming while accessing important content.

To deal with this situation, you need to use a browser or VPNs service which automatically deletes or prevents tracking cookies from your browser to track your location.

How does VPN work?

In addition, the functioning of VPNs is quite straightforward; it secures your network and all internet activities, hiding your IP address and redirecting your connection through a server.

It means your data can be seen by the VPNs host. But, the benefit of VPNs is that your Internet Service Provider and third-party users can’t see your online activity. So, your data is totally safe on the VPNs server.

You can say VPNs works as a tunnel for you over the network. With these benefits, Firstly big companies started to use VPNs to secure their private networks.

After some popularity and knowledge about working ability, normal people also started to use VPNs on their computers.

What are the Types of VPN?

There are four different types of VPNs that you need to know.

SSL VPN is also used to secure private network over the internet. Mostly got in demand when the Corona crisis started.

Because the companies which are providing work-from-home to their employees are not being able to provide devices to their employees.

So, most of the employees started to use their personal devices, computer, laptop, etc. Companies started to implement SSL VPN solutions through a corresponding hardware box.

4. Client-to-Server VPN

Additionally, the VPN Client proves to be highly beneficial for individuals who need to remotely connect to their company network from their home office through a computer or laptop.

If you use this VPN, then you don’t need to wait for an encryption tunnel on the existing connection. This VPN makes the tunnel phase short on the time of browsing through the VPNs.

This type of VPN is mostly helpful to secure public WLAN. So, any third-party user can’t access an internet connection and important data.
