VPN is an acronym for Virtual Private Network. As the name implies, a VPN service creates a “personal” virtual space in which you can work when you are online. With a VPN service, you can create a private network of selected devices, which is ideal for teleworkers. Thanks to this network, your team can stay in touch with each other in a secure way, even when the members of the team are far away from each other, or at continents apart.

Enhance Security

If you log into public Wi-Fi hotspots, a VPN service can keep your data safe. Public Wi-Fi can be very useful, but it is not as safe as your internet connection at home or at work. So, even if your Wi-Fi connection can be compromised, by creating a VPN service tunnel (like sort of a protective covering box), your data will be fully encrypted using a VPN service.

Your data cannot be decrypted until it reaches its intended destination. It means that with a VPN service you can surf, check your email or pay with a credit card securely, even on a public Wi-Fi network. This VPN security protocol is known as PPTP (point-to-point tunneling protocol).

Access to geo-restricted websites

Since a VPN service hides your location and lets you choose a server in a particular region, you can watch content from any other place. In certain countries, some websites and social media may be blocked. However, by configuring your VPN to give an IP based on your home country, your internet will display your connection as if you were in the country that you choose.

Avoid restrictions

A VPN service can also help you bypass network traffic restrictions. For example, if your ISP (Internet Service Provider) starts throttling your data after a certain limit, a VPN service can help you hide some of your online activities, thus expanding the advantages of using data.

How does a VPN work?

Essentially, a VPN hides your identity, your location, and your online activities. When you connect to the internet, your internet service provider (ISP) uses servers to get you online. Because a VPN service makes this connection through a private server, any data that may be sent from your computer comes from the VPN.

VPN providers use encryption and IPSec (Internet Protocol Security) to “package” your data so that it is securely prepared until it reaches its destination. This is known as L2TP (Layer Two Tunneling Protocol).

When you surf online, your IP address (Internet Protocol address) is not shown as the IP address your ISP assigns you, but as an IP address of the VPN server.

Why do people choose VPNs?

One of the most compelling reasons to use a VPN service in a working environment is to securely connect a remote team. With better security and accessibility, your team can work more efficiently. With a VPN you will have, therefore:

– More online trust: a VPN means you can trust that your data is safe, even when you share files;

– Customer trust: customers could expect you to have a VPN or an equally secure service before handing over documents, and finally

– Remote networking: a VPN service makes it possible to extend your internal network beyond the office.
