Having a good antivirus is important to prevent computer attacks and maintain good security on your devices. However, there are other varieties of security programs that can also be very useful. In this article, we are going to talk about the reasons for using a firewall together with an antivirus today. We are going to explain to you how it helps to enhance security.
A firewall is another option to protect devices and connections. It can be very interesting to enhance security and prevent certain types of problems. As always, choosing a good program will be key to really take advantage of it and not have any problems.
Why use a firewall
We are going to give you some reasons why it is interesting to use a firewall today. You will see that it could be very useful to enhance security and prevent intruders on your devices and your connection. Easy to use, you will have many options available and you will see that they are a good complement to the antivirus.
Avoid unwanted connections
The first thing you can do with a firewall is prevent your device from connecting to certain programs that use the Internet. For example, if you have applications installed on your mobile that require Internet access, this may sometimes not be secure. A firewall will prevent those connections without your permission.
You will be able to configure it as you wish. You can create lists of applications that you do allow to connect to the network, but also others that, on the contrary, you prefer to remain offline. An antivirus does not allow this.
Protect home automation devices
There are more and more smart devices that we can use in our daily lives. We can name some of them, such as light bulbs with Wi-Fi, plugs, sensors… Although they are very useful, we must keep in mind that, sometimes, they can pose a security risk if we make mistakes. For example, there could be vulnerabilities.
Having a firewall will better manage connections and prevent unwanted access. It will reduce the risk that an attacker will be able to exploit a flaw in a device of this type and put security at risk.
Stops certain attacks
Although it acts differently from an antivirus, a firewall could also help stop certain attacks involving malware. It can block unauthorized traffic and potentially suspicious IP addresses. This will prevent you from falling into the trap and the system from being infected with some type of malicious software.
This does not mean that it can act as a substitute for the antivirus, but as a perfect complement. It can help increase protection and thus reduce the risk of having cybersecurity problems related to malware such as viruses, Trojans, etc.
Improve privacy
By blocking certain connections, you will also achieve an improvement in privacy. You will ensure that your personal data is more protected and prevents it from ending up in the wrong hands, who could use that information against you, to create personalized Phishing attacks and other attacks.
However, even if you use antivirus and firewall, it will always be up to you to protect your data. Avoid giving more information than you should, do not give facilities to cybercriminals and protect your accounts well.
In short, to improve the security of your mobile or any device, beyond using an antivirus you can also have a firewall. It is a perfect complement. Make sure you buy one that has guarantees.
