What are the Benefits of Using a VPN

For Online Security Even When You are Using Public Wi-Fi

What does a VPN do? Well, the first thing it does is ensure your safety even when you are using a free public Wi-Fi network. It allows you to check emails, browse different sites and do your social media activities without worrying about data theft. Further, a VPN creates a safe tunnel so that your passwords, IP, and other sensitive data remain safe from hackers and vigilant bodies.

Stops Your ISP from Interfering

One of the most important things a VPN does is protect you from your internet service provider. Your ISP will not be able to track your online activities and have access to your traffic or data. As a result, your ISP will not be able to throttle your traffic flow and internet speed.

Say Goodbye to Government Surveillance

How to evade government surveillance? Many countries like the USA and the UK today are parts of 5, 9, and 14 eye surveillance. Further, these countries have strong digital laws and data retention laws. Because of all these regulations, your online activities are getting constantly monitored. A VPN will safeguard your IP and keep your online activities anonymous with a strong security protocol. Thus, you will be able to evade these restrictions and avoid punishments for breaking the law.

Stream Your Favorite Website from Anywhere

Today, digital streaming platforms are available in their defined territories. Irrespective of your geographical location, a VPN will let you connect to a server present in a location where your favorite streaming site works. Thus, sitting in India, you will be able to stream a site that is only available in the USA. In a nutshell, a VPN will let you watch any site from anywhere in the world.

Remote Working Facility

What is a VPN and how does it work in making remote working safe? Well, first of all, it encrypts all the data and makes it impregnable. Some VPNs offer application-based encryption, but the most reliable ones have both system-based and application-based encryptions. Further, it does not matter where the employees are geographically located. Connected by the same virtual private network, there will be easy accessibility to the device of every employee. Moreover, VPNs make file sharing safe through strong encryption.

Helps You Save Money by Spoofing Your Location

You already know what is a VPN and how does it work to hide your real location. You can use this facility while booking tickets and availing yourself of other online services where the charges differ based on your location. For example, you are booking an air ticket, and the charges are higher in your location and lower in some other place. You can connect to the server of that location and make the purchases at a lesser expense.

Helps You Bypass Geo-Blocking

Evading Geo-blocking is the first thing if you want to know what is VPN and why it is needed. It helps you connect to a chosen server. This is important because geo-blocking, or digital laws, make certain sites inaccessible beyond a particular territory. In simple words, we cannot access all digital platforms from any part of the world. This is where a VPN steps in, as it will allow you to evade censorship by connecting your connection to a server located in a place where Geo-blocking is not applicable.

Offers Safety for Financial and Banking Transactions

What is VPN and why it is needed to ensure safety in financial transactions? If you already know what is VPN technology, you will have an idea that it will keep your data and traffic protected. This is essential for maintaining safety in financial transactions. Further, a VPN will ensure that the credentials or details of your online banking accounts are never stolen through powerful encryptions.

In addition, you may be located outside your real country at this moment. Logging into your banking account from a foreign country can be problematic. A VPN will help you hide your IP and have the IP of the location you want to. Thus, you can still have your country’s IP while traveling or residing in any other country.

Making Remote Working Safe and Easy

A VPN also makes remote working safe with control access. It means that every employee does not need to have access to confidential data. Anyone trying to access confidential data needs to log in and have a verified authorization. This is an important aspect if you want to know what is VPN and why it is needed.
