What is VPN?

VPN is the acronym for Virtual Private Network. In a very summarized way, it is a set of private communications, built on a public network. For example: the public network would be the internet, while the private network would be access to Netflix. It is necessary to be connected to the network, but that is not enough. The user needs to access their own private account, which uses VPN, to “ensure the security of their account”.

Understanding VPN and How to use it?

It is a secure and encrypted connection. However, data traffic continues to be carried over the public network, which is used with all traditional protocols and standards. Sometimes, this path may not be so safe and can be hacked with bad intentions. In this sense, the VPN is quite useful to secure this path, knowing exactly where it goes.

The great benefit of VPN is turning insecure networks into safe options for users. That’s because it uses encryption and tunneling (or tunneling) protocols. This phenomenon consists of encapsulating one protocol within another, allowing a packet to be sent securely over a public network. This makes them have greater authentication of data, going through processes of greater confidentiality and integrity of the information being transmitted through this “tunnel”.

Also, to establish this secure network, some protocols are applied. Some of the more common ones found on most VPN networks are listed below. These Protocols helps to enable a secure connection, meeting different types of needs.

  • Layer 2 Tunneling Protocol (L2TP)
  • L2F
  • Point-to-Point Tunneling Protocol (PPTP)
  • IP Security Protocol (IPsec)

Another important point is that VPN naming can only be assigned to remote access services. An example is the Remote Access Service, better known by the acronym RAS, which is found in Windows versions from 2000 onwards. Another option is the Secure Shell (SSH), available on GNU, Linux and other Unix variants.

VPN Types:

  • Host-to-Network: Also called remote access, it can connect a single computer to a network.
  • Site-to-Site: Connects a single computer to two networks.

VPN Benefits

VPNs can be very useful in corporate environments, allowing employees to access data remotely. VPN services are highly used by companies, users who want extra protection, people who travel a lot and work with the internet or need it to perform their functions. That’s because it’s a best way to ensure that no matter which network you use, your connection will be secure.

It is common for users those who need to make multiple downloads on their computer. Some even prefer to use unusual systems to obtain services and in these cases, the use of VPN becomes even more recommended. Another common user profile is those looking for and performing illegal file installations.

There are some other safe options that use VPN. Opera browser uses built-in VPN technology options, without the user having to register on another system. Obviously, if someone already uses their own service and wants to port it to their browser, they can do that without any problems.

Is VPN really important?

VPN has many uses, especially in the business sector. Despite this, when some non-specialized user looks for this solution, it is quite common that it is to circumvent some system. The main one is access to streaming catalogs from other countries and to have greater access to available movies and series.

The uses are much greater and can be essential for the development of works. For a user who just wants to protect their data, make a more secure connection – but doesn’t have very sensitive information – Opera itself can meet the needs very well. Now, if there is a need for even greater protection, one of the many services available may be able to meet the security demand.

During the Covid-19 pandemic, several sectors of the industry were affected. Several companies started to do their work remotely and adapt to their needs. The use of VPN was one of those that registered a lot of increase in this period. That’s because, using technology, employees are able to connect to the company’s private network, even though they are geographically distant from it.

Using a VPN guarantees that all information will be encrypted and will not be interfered by hackers. This is an extra protection, which ensures more secure information. Despite this, it is worth some additional care, as we have already mentioned throughout this article Understanding VPN and How to use it?

Precautions when using a VPN

Nothing is free is this entire world. The profit that companies make from selling data is huge. This saying became very famous after the Cambridge Analytica scandal, when it was discovered that Facebook had been trading the information of its users for years.

Where does this apply for VPN? Let’s remember that the service has access to all user information to make it “safe”. However, some services may use this data to make their profit. So what you would use for greater security ends up having the opposite effect.

So, when hiring a VPN service – whether it’s paid or free, but even more attention to free services – it’s good to make sure that it really is a serious and safe option. Do research before subscribing to any service, watch videos and read comments from existing users for their feedback or review.


VPN is the acronym for Virtual Private Network, in free translation “Virtual Private Network”. It is a secure, encrypted connection built “on top” of the public internet network. VPN naming can only be assigned to remote access services. The most recommended VPN services are paid, but there are good free options.
