Virtual private network or VPN is a safe channel between two or more devices provided via the Internet. The mechanism is used to protect the privacy of web traffic from interference, snooping, and censorship. This is the most reliable way to connect to the Internet without risking your privacy, online data, and financial assets. In the world of cyber hacking, government prying, and hunting for your data VPN becomes in high demand. And you certainly need to know how to use it and why it is required.
The History of VPN
VPN-technology appeared in 1996 when Microsoft employee Gurdeep Singh-Pall co-authored the first VPN protocol. To be exact, he developed the peer to peer tunneling protocol (PPTP).
First, the technology was applied only for corporate use, and it wasn’t meant for the home Internet users. Companies needed a private network that could keep their internal secrets and be secure for all the workers.
And then for their demands VPN with its powerful encryption appeared Thus the safe network use was established.
Bringing VPN technology to the end users was implemented by VPN providers. With a time, Virtual private network increased in popularity due to modern global challenges.
Commercialization of world wide web, unwanted products, and features, blocking of the particular sites, restricting the content by geolocation, censorship of government authorities, cybercrime and so on led to the necessity of safety and anonymity of users.
Nowadays VPN offers a solution to all these issues and solves most of the Internet safety problems. That’s why approximately 25% of all Internet users choose VPN technology for surfing the net.
How Does VPN Work?
Every time you connect to the Internet, there always will be a mediator between you as the user and the Internet itself. It can be a provider or sometimes a public provider’s Wi-Fi hotspot. In this case, information from the user to the provider or public access point on the way to the Internet is transmitted in an unencrypted form. That means your data transmitted via the Internet becomes unprotected.
When you connect via VPN, the technology creates a kind of virtual tunnel between the computer and the server. In this tunnel all information is encrypted. Neither your provider nor hackers will decipher the data which you are sending through the Internet. Even connecting to public WiFi, you are not risking the safety of your data. No one can steal it or watch the history of your web scrollings.
The basis of VPN technology is simple: the connection established through a virtual tunnel is safe from any attempts of intruders to get to it from the outside. For the users, the work of the VPN is transparent and unnoticeable. Nevertheless, the results of a working VPN are tangible. You can be sure that your private and business correspondence, conversations on Skype or telephone won’t be intercepted. The special encryption algorithm encrypts your data, and hacking becomes almost impossible.
VPN also provides protection of logins and passwords, the history of visited sites as well as sites blocking. No more fear, danger and restricts on the Internet!
VPN Benefits: The Best Thing Since Sliced Bread
VPN allows you to use the Internet freely and anonymously.
Replace your current IP address with an anonymous one
Initially, the VPN was developed for creating a tunnel for remote access to the computers at a distance. This goal was successfully achieved. However, later VPNs were often used to switch between different IP zones. Today, VPN is used only for one task - protecting the current IP address of the user by replacing it with the IP addresses of the network servers.
When we connect to a VPN, our real IP address is replaced with the IP of one of the VPN servers. It gives us an opportunity to access blocked sites and to keep your real IP address anonymous. So even your provider won’t be able to track you by digital footprints. Your ISP will only see encrypted traffic, and the sites you are visiting will only be able to find out the anonymous IP address provided with VPN. Thus, your personal data remains intact.
Encrypt your data
VPN is the best encryption tool. Your data is transferred over the Internet in the form of a package. With the tools available on the Internet, these packages can easily be intercepted by anyone. Encryption does not allow outsiders to read your correspondence and spy on activities on the network. VPN is the only tool that provides reliable AES256 encryption with an 8192-bit key.
Bypass censorship and geoblocking
Nowadays internet-restrictions exist in many countries. These are China, Iran, Saudi Arabia, the United Arab Emirates, Egypt, Bahrain, Cuba, Brazil, Thailand, Russia, and others. That means that the government of such countries block access to particular websites and social networks. Just imagine, there are places on Earth where you can’t use Facebook, Twitter, Gmail, Vimeo, Spotify, Youtube, iTunes, Amazon Video, Skype, Facetime; and this list is somewhat incomplete.
The Internet users are interested in avoiding such restrictions, that’s why they use VPN. The technology gives the best solution to censorship and geoblocking. Data encryption performs an opportunity to hide your location and VPN also lets you select a server, for example, in the US or the UK, that do not provide tough control on the Internet users. With a VPN you can easily visit any sites and freely say what you think.
Protect your WiFi connection
When you use public WiFi (for example, in a cafe or at the airport), all your web-activity can be viewed and tracked. With a high degree of probability, the person sitting next to you can read all your correspondence and transmitted data. The worst thing about this whole story is that hackers easily create "evil doubles" of public WiFi-points, to which you connect instead of a real access point. So you fall into the trap.
When you are connected to a public unprotected WiFi, all your data like your credit card information, for instance, can easily be intercepted by hackers. Thanks to a complicated cypher (high reliability brings it closer to military technologies), VPN becomes protection for the browser and keeps your data from hackers and spies.
How to Use VPN?
Both free and paid VPN services can be found on the Internet. Which one to choose depends on the tasks that you will perform on the web. Free VPN’s frequently have restrictions on the amount of traffic and data transfer speed. Sometimes they can be overloaded and your Internet becomes catastrophic.
High throughput, an absence of limits, both on traffic and speed, and the level of security are higher than for free ones characterize paid VPN services. The subscription price for a month varies from 2 to 15 dollars.
To configure a VPN, you do not need to be a programmer. Having chosen the appropriate service, all you need to do is select the country with the needed IP, click "Connect" to start and "Disconnect" when the session is over.
There is a variety of apps that offering you to upload the VPN directly to your gadget. Perhaps, you are not ready to pay for using such applications, don’t worry there are loads of free apps as well. On our site, you can select an optimal variant among Hotspot Shield VPN Proxy, SuperVPN Client, Turbo VPN Unlimited, Betternet VPN WiFi Proxy.
