20 Mar Protect Your Privacy and Anonymity: Purpose of VPN
Only a small fraction of the world’s total number of users have an idea of a virtual private network (VPN). It is a sad fact that majority of today’s internet users have no idea what it is and the purpose of VPN. Having a VPN is as important as having an internet connection, and if you truly want to browse the web completely safe, getting one would be one of the best decisions of your life.
More than connecting remote users to a single, reliable network, the purpose of VPN is to provide you security and complete anonymity while using the internet. Whenever you’re online, all your data goes through an encrypted tunnel which makes it impossible to read if it ever gets intercepted. It also provides you a different IP address, so tracking your computer would be a difficult task.
You might think that web proxies and a software that hides IP addresses are better, but using a VPN whether at work or at home has many other advantages. So if you find yourself asking “Why do I need a VPN?” read on below to know the true purpose of VPN and why you should get one now.
What Is A VPN?
A Virtual Private Network (VPN) provides users a secure private connection even if they are remote and not physically on the same local area network. The data that you’re sending and receiving are encrypted to make sure that nobody can intercept it and use it fraudulently.
Using a VPN has many advantages aside from securing your data. VPNs are fast and reliable – you can access it any time you want even if you’re in a remote location. The bandwidth and network efficiency are also improved with a VPN solution. You can also browse the web in complete anonymity, and the maintenance cost for a VPN network is considerably low.
How to Setup A VPN?
Setting up a VPN with Windows is pretty easy. Simply go to the System Settings and click VPN on the side menu, or you can type ‘VPN’ on the search box and click on the System Settings option. You can then add a VPN connection on the ‘Add a VPN connection’ option.
If you want to connect more devices to your VPN server, you can set up or purchase a VPN router. Using a VPN router will automatically connect any device to your VPN server as soon as it is connected to your Wi-Fi. It’s quick, easy, and a real time-saver.
There are numerous VPN services out there with their unique features, and setting up has been made extremely simple. However, it’s always good to know how to choose a VPN and to understand how it works so you will have a clear perception of the purpose of VPN.
First, you have to pick a protocol. Different VPN services have varying protocols, and having a bit of knowledge about each one will help you pick the best VPN service that suits your needs.
Secure Sockets Layer (SSL). VPN services with the SSL protocol means that they are using an industry standard protocol, the same one used by banking sites. All data that passes between the server and the browsers will remain private and integral, which makes it easier and more reliable to use than the others.
Layer 2 Tunneling Protocol (L2TP). L2TP doesn’t provide confidentiality or strong authentication itself, so Internet Protocol Security (IPsec) is used to provide these. L2TP and IPsec can be a bit tricky to set up, and could experience some connection problems.
Point-to-point Tunneling Protocol (PPTP). PPTP is the least secure among the three, but it is a great starting point for VPN beginners because it is easy to set up. Plus, it is also widely supported by almost every operating system like Windows, Mac OS, Android, and iOS.
Why Use A VPN?
It ensures your security. Whenever you connect to an untrusted network, such as a coffee shop’s Wi-Fi, you’re putting your data in a potential danger. This means that checking your email, typing in your bank account details, or logging in to your social media accounts could put you at risk for hacking and identity theft. The first purpose of VPN is to secure all the information that you enter from your devices to keep it away from prying eyes.
It enables you to access resources anywhere. Using a VPN helps you become more productive because you can take your work with you wherever you go. Whether you’re traveling to another country or simply staying at home, the purpose of VPN is so you can access resources anywhere you are at any time you want.
It helps you save money and time. Using VPN for work is very convenient for you because you can communicate with your colleagues and do your tasks at the comfort of your own home. Many businesses have been using VPNs in their virtual workplaces because another purpose of VPN are its convenience, practicality, and security advantages.
It lets you download online safely. Many people use a VPN when downloading from BitTorrent to protect themselves from charges against illegal downloading. Some users also use a VPN even if they are legally downloading, to hide their usage and to keep hackers from snooping in on their downloaded files.
It bypasses geo-restrictions. A VPN bypasses country restrictions which allows you to watch TV shows as they air or download apps which are otherwise unavailable in your location. To do this, the VPN bluffs your IP address – including the apps on your computer and phone – which changes your location. This last purpose of VPN makes downloading and streaming more convenient for users around the globe.
