A VPN is simply a private network consisting of two of more computers connected together on the Internet using an encryption protocol to secure the content of communications. This ensures that no 3rd parties are able to eavesdrop on the communication between the computers in the VPN. Unlike a proxy service, once a VPN connection is established, all incoming and outgoing traffic between the computers is encrypted. It therefore encrypts not only your web browsing, but also your email, Skype, VoIP etc. Most importantly, your ISP (or anyone else), cannot log, view, or control your Internet activity whatsoever.
From the perspective of websites and other services on the Internet, when your VPN connection is established your traffic will appear to originate from the VPN server. Therefore, if you connect to a VPN server in the UK your IP address will indicate that you are located in the UK. The best VPN services will provide you with access to many different servers in multiple countries. Your actual IP address and location will be completely hidden and impossible to determine unless you voluntarily give this information out e.g. when completing an online form etc.
Benefits of a VPN
When VPN was first designed, the sole purpose of the invention was to create a tunnel between distant computers for remote access. And, it was successfully achieved. But later on, VPN was more commonly used to switch between different locations IPs. Till to date, the sole purpose of a VPN is protecting the original IP of its user by simply hiding it with one of its own servers.
In simple words, when we connect to a VPN, our original IP (assigned by the Internet Service Provider) is replaced by one of the VPN servers’ IP. For example, if your ISP assigned you an IP of London (as you are in London) 220.127.116.11 and when you connect to a USA server via VPN your IP will change to 2.354.452.2. This way not only you can access the blocked websites from USA, but your original IP will remain anonymous and not even your ISP can track your online footprints.
VPN is the best tool for Encryption. When you transfer your data via the internet it travels in forms of packets. These packets can easily be intercepted by anyone using simple tools available on the internet. Just take an example of an open Letter. You send a letter to your girlfriend via her friend. The letter is not enclosed in an envelope, so anyone who can have hands on it, can easily read it. But, what if you enclose the letter in an envelope and then glue it perfectly. This way no one can open it.
Encryption is like the envelope and glue, that makes it harder for intruders to read your conversation and spy on your online activities. VPN is the only tool that provides strong AES256 encryption with a 8192bit key.
Rapidly increasing censorship and diminishing rights of Freedom of speech, boost the demand of a VPN. In many regions of the world, you are not allowed to express your thoughts and opinions.
A VPN is the best solution to avoid Censorship and Geo-restrictions. If you are in a country like Uzbekistan or the Republic of Congo, where expressing your opinion is strictly prohibited, you can connect to a VPN and select a server like USA or UK. Now, you can easily access the websites and express your thoughts freely.
When you use a public WiFi connection (say at a Starbucks or at the airport), your entire browsing activity while connected to that hotspot could be monitored and spied on. It is very much possible that the next person sitting beside you can read your communication easily. The worst part – it is very easy for hackers to create devil twin Wi-Fi Hotspots, which may confuse you if it is the original one you are connected with but in real, it is a trap.
When connected to public, unsecured Wifi, all your data - including the most sensitive such as your credit card info - can be easily stolen by hackers. With strong and military-grade encryption, a VPN protects and secures your browsing session and keeps your data safe from snoopers and hackers.
Are you an expat living far from home? Or, are you a frequent traveler? Are you missing your favourite shows and movies on the home country channel? Well, with a VPN you can access your home country channels and watch all your favourites from anywhere.
Travellers usually face the problem, when they cannot access their online profiles and bank account due to a completely different IP. A VPN service can solve this problem too. With a Fixed or dedicated VPN IP, you can access your online profiles and bank accounts anywhere and anytime.
