VPN Write For Us
A VPN is a network technology used to connect one or more computers to a private network using the Internet. As we explained in the article about what a VPN is for, companies often use these networks so that their employees, from their homes, hotels, etc., can access corporate resources that they otherwise could not.
However, connecting an employee’s computer to corporate resources is just one of the functions of a VPN (Virtual Private Network). So, to Write For Us, you can email us at contact@techsupportreviews.com
How to VPNWorks
When a standard device connects to the Internet, the outgoing connection communicates first with the network service provider and then with the requested site or service.
On the other hand, if the device is connected to a VPN, the path is different: The device continues to connect to the service provider first but then communicates with a VPN server. Finally, it will be from the server that the connection will be made to the site or service to which the device wants to access. Also, all connections that are created when a device is using a VPN are made through what is known as a VPN or data tunnel. These have various characteristics, but the most important is that they encrypt the information that travels within them, making it unreadable for those who intercept it.
So, a VPN tool makes two modifications to how devices connect to the Internet: First, it adds an intermediary to the connection and, secondly, the cypher in all its sections. This first feature is responsible for camouflaging the original location of the device, as well as its actual IP address since the final connection is made from the VPN server. In addition, the encryption of the entire connection makes it one of the most recommended tools for protecting network connections.
Advantages of VPN connections
- Now that we know what a VPN connection is and what it is for, it is time to summarize a list of the advantages and disadvantages of using this technology. First, the positive part:
- It works in all apps, routing all Internet traffic, unlike proxy servers, which you can only use in your web browser and a handful of other apps that let you configure advanced connection options.
- Connects and disconnects easily tag. Once configured, you can activate and deactivate the connection at will.
- Additional security in WiFi access points, as long as the connection is encrypted, of course
- Fake your location, as we have already seen in the previous section, a VPN connection is an effective way to avoid censorship or access content limited to a certain region.
- Your Internet provider cannot know what you do on the Internet. Don’t you want your ISP to know that you spend hours watching kitten videos on YouTube? With a VPN they won’t know what you do, but beware, the company that manages the VPN will.
When to use a VPN
There are multiple reasons why a VPN can be useful. Its main uses are:
Remote work
Probably the most frequent use of VPN connections, this tool is essential for remote work. They are used by collaborators to be able to access the corporate networks of their organizations, and thus access services or sites within the same networks. In addition, by granting an encrypted connection, they are usually mandatory within those corporations that implement them, becoming a robust security tool that can prevent attacks caused, for example, by overexposure of corporate equipment abroad, as is the case of attacks on the RDP protocol .
Connections in public networks
A VPN is also often used when there is a need to access a public Wi-Fi network ; that is, it does not have any type of credential protection. And with the increase in virtuality, accessing public networks in places like bars, cafes, coworking spaces or airports is becoming more common, both for work and leisure. But since these networks do not have any type of verification, it must be a VPN tool that encrypts the connection, being protected both for those who can intercept it and for those who manage this network, who are often unknown to the user.
Censorship evasion
In countries where certain content is inaccessible or its consumption has legal consequences, VPN tools are often used to access it. This is possible thanks to the VPN server, which acts as an intermediary in the connection. Thus, network providers will not see the final destination of the connection and, therefore, will not be able to stop access to it. However, and because of this feature, there are recent prohibitions on the use of VPNs in places where censorship is common.
Location-based services
Not all uses of these tools are related to cybersecurity. There are services and applications, such as video games, online stores or consumption of series and movies that offer their content according to the country of origin of the connection of their users. Thanks to the change in the location of the connection, since the user’s location will actually be the location of the VPN server that acts as an intermediary, it is possible to consume content from different locations. This is also why several tools of this type offer the possibility of choosing the country or region from which the outgoing connection to the Internet is made.
In short, a VPN will be useful when we have to protect a sensitive or previously insecure connection (such as a public Wi-Fi network) or when we want to hide or modify the location of the connection.
