A solution for the protection of your data

When we evoke data security, anonymous surfing or its protection against online services such as geolocation, the VPN systematically comes back in discussions.

Even if the network infrastructure used by VPN mechanisms remains the Internet, which is nevertheless the most widespread tool in both personal and professional use, it is inherently insecure. As such, it is therefore important to take measures to protect yourself from the limitations of an unprotected “public” network.

The Internet is a land where cybercrime is ubiquitous in all areas.

Data protection

Cryptography, a technique that ensures the confidentiality of information, transforms data readable by a digital algorithm into encrypted data incomprehensible to unauthorized persons. The decryption function performs the reverse process. The type of encryption used, like the type of authentication used, depends on the communication protocol adopted by the service provider.

There are countless vpn services offered on the network. The research and the choice must be carried out according to its real needs, and by correctly evaluating the various optional functionalities offered. In addition, it should be borne in mind that in order to take advantage of all the features of a good VPN, it is better to move towards paid solutions.

Whether it is about its confidentiality, the security and the protection of its information, it is essential to use a reliable solution, therefore paying. Free VPNs always have a different purpose, which will serve the interests of publishers in one way or another. Paradoxically, they can recover your details and resell them to third parties. Nothing is really free without a reason that serves the interests of any business.

Here are the reasons why you should always keep in mind that a VPN should protect your data.

What is a VPN?

A VPN is a virtual private network which guarantees confidentiality, anonymity and security through a logically reserved channel created on a public network infrastructure. The term virtual means that all devices belonging to the network do not have to be connected to the same local network, but can be located anywhere in the world.

A VPN is therefore a special network service that can be used to encrypt Internet traffic and therefore protect your online identity.

In a purely professional context, a VPN can be compared to a geographical extension of the private local network. It therefore makes it possible to securely connect the sites of the same company which are located in the territory.

To do this, the routing of data packets via the IP protocol is exploited for transport on a geographical scale: this makes it possible, in fact, to create a virtual and private local network, but quite equivalent to a dedicated physical network infrastructure.

Who uses a VPN for data protection?

VPNs are mainly used in the corporate sector and by the public administrations, in particular for the possibility of reducing the costs in the creation of their own protected network created, precisely, by exploiting the infrastructure of the public network.

However, there are also many private users who prefer to surf the net via a VPN, in order to be able to explore and exchange data on the internet securely, and without restrictions or geolocation.

Among the various services available, some providers also offer the possibility of choosing the protocols to be used for the connection. You can thus opt for a VPN server installed in the supplier’s network, whether professional or private, or to connect one which is managed by a third party.

As a reminder, if your data on the Internet is not effectively protected, it can be intercepted by anyone in their path. This is thanks to sniffing techniques, where it becomes interesting for certain players to know the details of your online activities, with different objectives: investigation, trade or fraud.

Connection with a VPN for data protection

Remote access connections allow users, for example, for intelligent work, to access a server on a private network via the Internet. This type of connection can be thought of as a connection between a VPN client PC and the company server. As already mentioned, from a logical point of view, it is as if you have a dedicated and private connection.

A site-to-site connection is used to connect in a private network, always with the help of a public network. Offices located in several locations or other organizations, thus allow routing and secure communication. In this scenario, each office will have a dedicated router, that is, a node in the VPN network, which will route the data packets to the peer recipients. All this according to a client and server model, by sharing information with remote offices in a completely transparent way.

Although VPNs were created for business purposes, they are also very often used by people who care about the security of their data and their internet browsing in general.
