Maintaining security when we connect to the Internet is very important, which we must always keep in mind. Many wireless networks are around us, but not all are secure. We can come across a Wi-Fi that is enabled simply to steal information. In this article, we will talk about Firewall VPNportable VPNs and firewalls that we can use to protect ourselves and browse the Internet more safely.

You have always heard of the Windows firewall, but what is a Firewall VPN in computing? It is one of a computer’s primary protections against external attacks. 

Why it is dangerous to connect to insecure networks

Nowadays, connecting to a Wi-Fi network is very common. We have many options at our disposal. We will find networks in airports, shopping centers, libraries… Practically in any public place where there are usually a lot of people. But of course, this also means that there may be insecure networks.

Hackers can set up a Wi-Fi network to steal user information. For example, viewing browsing history, collecting data, redirecting traffic… This can affect security and privacy when accessing the Internet with our devices.

To avoid these problems, we can use certain tools. An example is a Firewall VPN, whose mission is to encrypt the connection and allow browsing with greater security. They are instrumental when we connect to public Wi-Fi that we cannot trust. It serves to make the connection private and reduce the risk of problems.

Especially Wi-Fi networks that do not have encryption or use outdated encryption could be a greater threat. Hackers may have created them as bait; worse, even a legitimate network could have been attacked and used to access other computers that connect. However, beyond thinking only at the software level, we can also consider physical devices. We are going to talk about it. We are going to explain what a portable Firewall VPN is. Two types of physical equipment that could help improve our security when connecting to a network.

Firewall VPN, a security solution

We all know that many programs can help maintain network security. We can talk about antivirus, firewalls, and browser extensions. We can find this for all types of operating systems since none is 100% secure and free from attack.

Now, beyond computer programs and software, we must also think about hardware. Some devices can help us improve security in our daily lives and even when traveling since we can find portable options.

That’s where Firewall VPN comes into play. Both devices allow us to help improve security and avoid risks when connecting to the network. We can even carry them physically and use them anywhere. They serve as complements to security programs that we install and that we can use in our daily lives on any device.

Portable VPN

A VPN is a very useful tool to protect connections. They improve security if we connect to a public Wi-Fi network, for example, since it encrypts the content and prevents third parties from accessing the information and compromising our privacy. It is common for us to install a VPN service on our mobile phone or computer, in addition to having browser extensions.

We also have the option of having a portable VPN. It is a device that acts as an intermediary between our equipment and the Wi-Fi network we access. Let’s take as an example that we are connected in a cafeteria or an airport. These are places where there are many users every day, and a hacker could create a network to attack.

A Firewall VPN device acts as a Wi-Fi router to connect to the network more securely. This type of device has OpenVPN or TOR clients and allows you to improve security when browsing the network. Integrated firmware allows our devices to have an extra layer of security.

An example is GL-AR150, a small device capable of becoming a secure Wi-Fi network so that we can connect from anywhere. They usually have a built-in battery, so we could even use it on a bus trip without electrical connectivity.
