What Is a VPN?
In simple terms a VPN (Virtual Private Network), refers to a group of computers, operating together over a public network—i.e., connected to the Internet. When connected to a VPN, what usually happens is that you launch a VPN client, then you log in, the computer then exchanges trusted keys with a server that is quite far away. Having verified each other as authentic, both the connected computers can now enjoy encrypted communication, secured from eavesdropping. Most businesses rely on VPNs to connect to remote data centers.
Likewise, an individual can equally use VPNs to get access to a computer network even when they are not physically on the same LAN. You can also use a VPN to secure and encrypt your communications especially when you are using an untrusted public network. You are going to need a VPN if you want a reliable way of bolstering your security and access resources on a network that you are not physically connected to.
Advantages and Benefits of a VPN
Connecting to a Remote Network
A VPN allows you to access a remote network anonymously. For instance, you could be too far away from the office, but you desire to obtain some company data. With a VPN, you can remotely access the company data easily and achieve your objectives. The VPNs encryption also hides your IP address. You could be surfing from Germany, but your VPN provider is in France or any other country. Your IP address that will be displayed is France’s rather than your actual Internet Service Provider’s.
Securing a Wi-Fi Hotspot
If you have a VPN, you will be immune to hackers who may want to access your data via WiFi hotspot (no matter how creepy they maybe). Even if the hacker entices you and coerces you into connecting to an “evil twin” network, he won’t stand a chance of stealing your data as the VPN entirely encrypts it.
Confidentiality When Using a Connected Device
Since VPN allows you to hide your IP address, it means you can browse the Internet and gain access to different sites with the utmost confidentiality. The good thing about it is that you can achieve this on any laptop or a connected mobile phone.
The most crucial aspect of a VPN you should know is that it secures your computer’s internet connection. It is quite a guarantee that the data you’re sending and receiving is encrypted and secured. You can then go on with your work knowing too well that nobody is eavesdropping.
