If you are not using a VPN, you probably don’t know what it is and how it helps you to keep your private data private. The truth is, you really should be using a VPN next time you go online. Read this article to find out more about Virtual Private Networks and why you need one.
What is a VPN?
A VPN or Virtual Private Network adds a layer of security and privacy to your private or public networks such as the internet. Businesses use VPNs to connect to remote data centers and to protect their sensitive data. But individuals can use a Virtual Private Network as well to maximize their security on the net especially when they are using a public network.
A virtual Private Network ensures that all you internet traffic that you send or receive is encrypted and it is safe from prying eyes. Such networks replace user’s initial IP address with one from the VPN provider. This allows you to stay anonymous on the internet. For example, you may be living in New York, but your IP shows that you are in Amsterdam or anywhere else. This will provide privacy for you as it hides your internet activity from ISP (and government). You can also evade censorship and hide your location to use services which are unfairly denied from you merely because of your geographical location.
How does a VPN work?
Normally, when you connect to the internet, you first connect to your ISP or Internet Service Provider. You ISP then connects you to any other website that you would wish. In this way, all you traffic data is transferred through your ISP servers and can be viewed by your service provider. When you use a VPN, you access the internet through a private server through an encrypted connection. An encrypted connections means that only you and the private servers can see your data. No in-between person would be able to eavesdrop your data.
How can you benefit from using a VPN
There are a number of reason why you would need a Virtual Private Network for your internet connection. These networks prevent someone from spying on you. Virtual Private Networks are a secure tunnel through which your data travels back and forth so these servers do the work to prevent anyone from snooping your browser history. Your computer connects to a VPN server which can be located anywhere in the world so your internet browsing won’t take place from your computer’s geo-location, but from the server’s location. This way, you can go online with full anonymity and maximize your protection against people who would want to spy on you and your personal data. The fact that security threats are evolving everyday creates greater need for private networks. VPNs use advanced encryption protocols and secure tunneling techniques to ensure your safety on the internet.
Does VPN use mobile data?
A VPN privatizes your online activity by adding a layer of encryption to your data that is transferred through its severs. A virtual Private Network places a few extra bits of data onto each packet to encrypt them accordingly. These extra bits of encryption obviously equal more bits of data being transmitted in the end, which adds up to more mobile data being used. So yes, a VPN uses more mobile data. However, the overall amount of data usage is insignificant. So you don’t need to worry about it much.
These are a number of different protocols which offer various internet security features:
PPTP – The main feature of the PPTP is that it can be easily set up on most of the major OS. In short, PPTP tunnels a point-to-point connection over the GRE protocol. However, its security has become under question in recent years.
L2TP/IPsec -This protocol is more secure than PPTP. L2TP/IPsec is a way of implementing two protocols together in order to gain the best features of each. And this makes an impressively secure package.
Open VPN – OpenVPN is SSL-based and open-source. SSL is a mature encryption protocol, and OpenVPN can run on a single UDP or TCP port, making it extremely flexible.
How to set up a VPN
The first thing you should do if you want to start using a VPN is to read reviews and recommendation. You need to choose a service provider which is trustworthy and comprehensive. So if you are about to start using a private network, these are the tings you need to consider:
Price – If you want to choose among the paid VPNs, you need to keep your eyes open and you need to consider the difference between a free VPN and a paid one.
Speed – Every virtual Private Network entails an amount of internet speed loss. These is caused by the process of encryption and decryption of your data which accounts for your privacy.
Privacy – All VPN providers promise privacy of your data. But do they really make you anonymous? Is your private data safe on their servers?
The most common way people get VPNs is through a monthly service. There are a ton of these. Ultimately, you must trust the company running the VPN, because there’s no way to know what they’re doing with your data.
