In recent years, teleworking cases have multiplied, many of them improvised due to the confinement we must undergo while the coronavirus health crisis lasts. For this reason, many companies have had to deploy a certain infrastructure to ensure that their employees can work normally.
The VPN is one of the simplest, most useful and most effective solutions to guarantee the connectivity of the workers to the company’s servers and that, ultimately, they can access the company’s intranet in complete security, in the same way, that they would if they were in their physical job.
A VPN is a Virtual Private Network, that is, a network technology that allows a “secure extension of the local area network” over a public network such as the Internet. The adjective “secure” is very important since the Internet is not a controlled network as the local network in the company can (or should) be.
In this way, the same levels of security, privacy, and isolation are achieved as they are in a private network, but sending and receiving data on shared or public networks. Thus, functionality, security, and management policies are maintained.
The way to achieve this type of connection is through dedicated connections, encryption or a combination of the two methods.
Uses Of VPNs
There are many use cases of virtual private networks, as we can imagine, although we are only going to focus on two of them, which start from the same base: the security and privacy of the connections.
Telework is the most obvious application of the VPN. Giving remote workers free access to local company networks is nothing short of crazy, since any communication over an unsecured network (such as public WiFi) can be intercepted and, in this way, credentials can be stolen, as well as any document or data, breaking privacy.
As An Extra Layer Of Security
VPN connections often have some form of encryption for transmitted packets. It is that extra layer of security (encryption) that the VPN offers us, which makes connections to sensitive systems such as bank accounts or access to customer databases secure.
There is a trade-off in all of this, and that is that we have to completely trust any top VPN providers. In other words, if we distrust the public network (a public WiFi, for example), but blindly trust the VPN provider, we may be putting our data in danger.
For this reason, and of course, companies have their own VPNs, deployed by their IT departments, or they rely on trusted partners with long experience and experience, as well as good references from former clients.
