There are several types of VPNs, including:

  • Site-to-site VPN

It connects two networks through a secure, private tunnel so that they will transmit information to the same source;

  • Remote access VPN

This type of VPN allows a user to connect to a specific organization or other institutions via their VPN. A VPN application is required to connect to the other end: SSL or IPsec.

  • For example: an employee working from home will be able to connect to his workplace through such a network. The employee will benefit from either all of the company's resources, or only from some of them, those necessary for his position in the company.

Remote-access VPN can also link a user's computer to organizations in different countries through a secure, private channel that does not track the client's location.

A user uses a local network to access various services in the online environment; thus, the virtual one knows the source of access requests on various sites and applications. The source is the local network to which the user is a client, also known as LAN; local area network.

Ce înseamnă acest acces de informații prin LAN? Înseamnă că serverele și rețelele folosite vor cunoaște adresa IP a dispozitivului digital de pe care umblă utilizatorul. O adresă IP – internet protocol address, arată lumii publice a internetului adresa particulară a sistemului (calculator, laptop, telefon mobil) utilizat.

With the help of a VPN, all this information will be detached from the original source, the user's device, and will be attached to this network that will generate a different and secure IP address. In other words, your browsing history, downloaded files, banking details and passwords will be harder to decipher online because the VPN offers both data encryption in a cloud SECURE as well as their integrity.

Internet service provider 

The customer's Internet Service Provider (ISP) can only see the connection between them and the VPN service. The provider does not have access to the data, networks, servers, and information that a person uses within this type of connection. In other words, the provider cannot monitor the customer's virtual activity.

The firewall

The firewall, more commonly known as Firewall, limits user access to different sites.

For example, at a college library, students have access to the educational environment's servers. The student may have certain restrictions even if they use their personal devices, but connect to the institution's Wi-Fi network. At work, an employee can only access websites and applications specific to the company's industry.

By using a VPN, both a student and an employee can browse the internet freely, accessing the desired sites.

Can users be tracked through VPN?

According to the functionality of the virtual private network, users' online activity is secured, encrypted, and private from the public landscape. Of course, and a cloud encrypts information, but a VPN presents a higher level of trust.

A good VPN provider will protect the user's identity and data from others who want to steal the customer's information or information about their online activity.

How does a user connect to the VPN?

Access to a VPN network can only be achieved based on user identity authentication. The classic method is to choose a username along with using a password. Depending on the operating system the client has, he must follow certain steps.

Windows

There are several versions of Windows, each with similar steps. If the user wants to install a VPN on their Windows 10 system, they need the IP address of the VPN they want to connect to and their VPN account information. In the "Network & Internet" menu in the settings, they have the option to add a VPN connection.

Android and iOS

For Android, there are two options: the classic one, a technique through which the user has to follow several steps to connect or create a network, or they can use one of the applications specially created for Android or iOS, following the steps of the application.

Is VPN legal?

Yes, it is legal. With a few exceptions, such as: Russia, China, Turkey, Iran, VPN is legal in the rest of the world. However, although this private network benefits from legality, it is the user's responsibility to distance themselves from illicit virtual activities that could put them or others in danger.

Users are familiar with the concept of the Internet's "Big Brother." It is encountered in the marketing field, when companies want to find out a person's preferences through their known cookie agreement„

However, users want to protect themselves from the government's panopticon (the equivalent of "Big Brother", a concept born in prisons and meaning a continuous watchtower), which is why they use a VPN.

What extra benefits does the VPN bring to the user?

Security

The main reason why a person uses a VPN is because cybersecurity  which it offers in relation to its identity and online data.

VPN is the protective shield between the user's system and the internet. Activity cannot be tracked because all information is encrypted.

Anonymity

With a VPN, the customer is protected from marketing cookies, as well as from other users and the internet service provider. Thanks to the hidden IP address, other people online will not know either the person or their location.

Unlimited information just a click away

A VPN breaks down the barriers of a user's country of origin, allowing them to access information that they cannot access in their place of residence. A common example is that of YouTube videos, some of which do not allow access if the customer is from a certain country.

  • Youtube and Streaming without restrictions

YouTube and streaming sites, such as Netflix, are among the most popular internet options among most users; these are the servers most often used by customers who prefer to listen to music or watch series without interruptions.

Local internet service providers often throttle their internet connection speeds to reduce data usage. It is frustrating for customers to watch a movie with lag caused by the internet speed. A VPN will fix this.

Another problem that users face is the one mentioned above. Some videos are banned in different countries. With a VPN, networks will not detect the country of origin, and the video can be watched.

Moreover, for streaming sites, it is often necessary for the user to live in a specific country to benefit from the desired materials. For example, the user can choose the UK as the VPN country of origin to be able to have the BBC online TV program for free.

  • Online games

Using a VPN will create a powerful experience for a player. On the one hand, due to the slowdown or interruption of the connection by the Internet service provider, online games can often be jerky (frame drops) and limit the customer's pleasure of spending time in such an environment. Often, in online games every second counts to make the right decisions.

A second advantage that VPN has in online video games is that other players do not know the person in front of the system, but only the avatar that they create and connect with within a platform.

At the same time, with the help of a VPN, a person can use the BitTorrent application without limits, through which he can download copyrighted materials.

  • Shopping without borders

A person who goes to a foreign country often buys souvenirs or products that cannot be found in the country they live in. Nowadays, most products are just a click away regardless of whether the online stores have the domain in the same country as the customer or not.

What is the use of a VPN in this situation, if you can buy products from abroad anyway? The VPN helps encrypt the bank account data through which the transaction was made, as well as the address to which the package will arrive. Of course, the destination website, the one from which the product was purchased, will know the address.

  • Connecting to Wi-Fi

Wi-Fi connections are encrypted private or public networks. However, in these types of connections, there is a possibility that a customer's data can be easily stolen from the device they are connected to the network with.

Also, in public Wi-Fi connections there may be a third party observing your actions and the websites you visit. With the help of a VPN, your Wi-Fi connections will be private and secure.

  • Holidays without cookies

When a person wants to go on a vacation, whether in their home country or abroad, they will research the transportation and accommodation market.

Thanks to cookies, websites will notice that this person is interested in certain services: accommodation, train transportation, mountain excursion groups, car rental, boat, etc. Because of this, there is a possibility that the marketing team will increase the price.

To avoid overcharging for services, a VPN hides the user from both cookies and the space they reside in.

Even more so by installing a VPN the holiday destination is hidden from the public eye of the internet.

  • Secure conversations

Most people use the internet as a channel for communicating with family, acquaintances, friends, colleagues, etc. Online communication means emails or written and spoken messaging services. Without installing a VPN, there is a possibility that conversations can be listened to by entities other than the primary ones.

  • The user lives at a virtual address

Thanks to VPN you can create a virtual "home". On the one hand, the VPN creates an online IP address, and on the other hand, the client can choose a fictitious address. This benefit is suitable for use against thieves who follow people when they go on vacation to go to their home.

The disadvantages that the VPN network may have

A VPN is a complex network that offers the user a unique and beneficial virtual experience. However, there are also some disadvantages to virtual private networking; for example:

  • Slow connection: The VPN encrypts a lot of information in real time, which means there will be brief moments where the connection will slow down slightly. This doesn't happen often;
  • Some sites block VPN;
  • Cost: there are free VPNs, but they have a limited offer, and there are premium VPN packages that cost monthly;
  • In some countries it is forbidden: as mentioned previously, VPN is legal in most countries;
  • Identical IP address: a VPN server uses the same IP address for multiple connected users. This only presents a problem if a client misbehaves;
  • Availability on devices: There are devices, especially older ones, that do not support VPN.

The user wants a strong and secure experience when using the internet. Online security is the essential component for a customer not to have to worry about the integrity of their personal and online data. A VPN hides browsing data, encrypts information, hides their real location and provides protection from other entities. The balance of advantages and disadvantages of a VPN network tends to weigh towards its benefits because it gives the customer access to the entire world of the internet.
