A VPN is an encrypted communications network environment in which access is controlled to permit peer connections only within a defined community of interest. This is constructed through some form of the partitioning of a universal underlying communications medium, where this underlying communications medium provides vpn services to the network on a non-exclusive basis.

What a VPN Does?

No matter where you use your device and on which network, you’re at risk of a data breach. Unencrypted data is very vulnerable to cyber attack, as is any information that comes through your browser that isn’t secure and protected.

Wireless networks, unusually public access points, are highly vulnerable to sniffers, or computer programs that are used to decipher the data to make it readable. This involves places that offer free Wi-Fi, mainly airports, hotels, and coffee shops. But as per the current situation of the world crisis due to the COVID-19 pandemic, half of the world is on lockdown, and corporate employees are doing work from home. This leads to cyberattacks to be more vulnerable as everybody is using there home network connection with less data encryption and firewall protection. Many companies are recommending their employees to use VPN while accessing their company profile and fetching essential data from the servers as they are at high risk.

Using a home network with a low level of security encryption and firewall protection can be an easy meal for the hackers to use sniffers to spy, steal data, hijack devices, and even steal identities.

While working from home can make you an easy target for anyone within about 150 meters, and as little as 100 meters, in some cases, and can get all of your data with the right knowledge and tools. And for the experts, it can also be done form a few kilometers. They can watch everything from your comments on the local news to your bank account number and password and all the highly classified data, making it a more significant concern for the companies who are getting their work done from home by the employees.

A VPN can help to protect and encrypt your computer and your vital information from sniffers and other types of hacks. Using VPN can get you the network encryption somewhere closer to the primary firewall and security level of an office network.

How can VPN protect?

A VPN encrypts or scrambles the information so that a hacker cannot see and grab the data form what a person is doing online. Typically, a VPN creates a type of tunnel that blocks hackers, sniffers, and internet service providers (ISPs) from breaching in and see your messages, web browsing history, payment card information, downloads, or any piece of classified information that you send over a network. This tunnel cannot be penetrated easily, and the transmissions of your data cannot be viewed.

The VPN connection is protected, and it can make any public network a pseudo-private network and increase the network encryption and security for those who use them. Also, the VPN can be used on any device, including laptops, phones, and tablets, and a user can choose from different VPN software providers depending on their needs and budget.

Perhaps most importantly, a VPN encrypts and protects data. This data can be of any type, including instant messages, e-mail communications, downloads, payment card information, login information, and the sites you visit. The VPN modifies your IP address, too. This creates an illusion of location shift and makes it seem like you are using your computer elsewhere around the globe. This also makes it possible to access sites like Facebook and other blocked websites that are blocked on the network otherwise.

How to choose a VPN

There are a large number of VPNs to choose from, like free Chrome plugins like Hola, Zenmate, HMA, and apps for mobile like Also, there are many paid VPN services available in the market that provides a high level of data encryption and also custom IP and location selection options. These providers also give special discounts on VPN and offer time to time, which makes it more affordable and considerable for low budget users.
