The Difference Between VPN Vs Firewall and Antivirus Software

What is the difference between a VPN and a firewall? Firewalls protect your computer from hackers, while VPNs keep your data safe. Firewalls and antivirus software are not the same things. The main differences are explained below. This article is about VPN vs firewall vs antivirus: which is more secure?

What is a VPN?

A virtual private network (VPN) hides your IP address, the sequence of numbers that identifies your device. It works by forwarding your network connection through a remote server and protecting you from those trying to find your location and other valuable data. A VPN is essential if you use public Wi-Fi or work remotely, as it encrypts your traffic and protects your information during transmission. It’s like a private line directly accessing a corporate server or a secure network anywhere.

When you use a VPN, your Internet service provider, government websites, and the websites you visit frequently have no way of knowing your proper location. A VPN is the best choice if you really care about privacy and data security while browsing.

On the other hand, as mentioned earlier, a VPN cannot protect your computer from viruses. You cannot set up security rules for VPNs. To monitor and delete viruses, you need antivirus software. It would be best to have a firewall to prevent viruses from entering your network and stealing data.



Antivirus and firewall software are essential security tools, but they serve different purposes. VPNs encrypt data, while firewalls block malicious websites. They can also protect your data but are limited in their ability to control traffic. Firewalls can limit your access to certain websites and the amount of data you can send and receive. While antivirus software scans downloaded files for viruses, VPNs encrypt data and protect your computer.

Unlike VPNs, antivirus suites usually offer fewer servers, and you can’t choose which one best suits your needs. They also do not unblock streaming sites or torrents. In addition, antivirus software does not offer full security features such as a kill switch or the ability to change tunnel protocols. Also, antivirus software can sometimes compete with VPNs for the same reasons. Regardless of the benefits, you get from either, you will be protected from various threats.

What are firewalls? 

A firewall monitors the incoming and outgoing traffic on your Network. Firewalls automatically block attacks and allow you to set security settings for what you let into your Network or computer. If you do not Program a firewall to block a specific type of site, content or traffic, this will not be the case, even if this site contains content that could harm your system.

There are two types of firewalls:

1. Hardware or network firewalls

Hardware firewalls are physical devices between your computer and the Internet. Their disadvantage is that they are separate devices, which often require professional help in configuration and maintenance.

2. Software firewalls

Software firewalls can monitor internet access and the behaviour of programs on your computer. Most computer operating systems (OSS) include a standard built-in firewall feature, but firewall software is also available separately from computer stores and trusted online vendors. 

Which one should you use?

The answer is both! Build a firewall with a VPN. A VPN like Avast SecureLine VPN hides your online activities and allows you to transfer data securely without slowing down your connection – even over public Wi-Fi. Still, it cannot protect your device from downloaded viruses or spyware. You may still be vulnerable if you click on a broken link on a malicious website. Thus, a firewall will inform you before visiting potentially harmful sites.

A firewall is a software or hardware device that filters internet traffic. VPNs, on the other hand, use encryption to secure network connections. They hide the user’s IP address and route network connections through a remote server. The VPN protects your device from cyber-attacks by preventing hackers from reading your private data. Firewalls and antivirus software have similar goals. Both have the same goal: to protect your system from hackers.

While firewalls and antivirus software can help protect your computer from malware and other online threats, they can’t provide all the protection VPNs can. A VPN connects you to the internet through a secure tunnel and allows you to access websites and content blocked in your country. A VPN is also useful for anonymous browsing. A firewall blocks malicious websites and prevents viruses and malware from damaging your computer’s operating system.

Antivirus Software

Antivirus Software

Antivirus and VPN Vs Firewall software have different purposes. Firewalls protect your computer from malicious websites, while antivirus software protects your private data and identifies malware. Both should be updated regularly. In combination, they protect your system from various threats and provide an extra layer of security. VPNs protect your private data and prevent it from being misused by hackers. Antivirus software is essential for any business environment but works best with firewalls.

While firewalls and antivirus software are essential cybersecurity tools, VPNs are not as effective. Antivirus software identifies and stops malware, while VPNs encrypt internet traffic and hide online activity. Although antivirus software and VPNs have complementary functions, both are essential for online security. Without antivirus software, your computer is vulnerable to malware. Fortunately, a VPN can be used by almost anyone. The free version allows you to unblock Netflix, browse the internet anonymously and access geographically restricted content.

Virus Protection vs Firewalls

Here are some specific differences between antivirus software and firewalls:

  • Antivirus programs scan your device to ensure no malicious software is trying to access your data.
  • Firewalls use your settings to block access to specific websites and restrict the data that a website, program or software can retrieve.
  • Firewalls are focused on blocking sites that you or the firewall company has determined to be malicious in the software. Antivirus software identifies and removes all malware after it scans your computer. Therefore, you must constantly update them to protect them from the latest malware.
  • “Antivirus protects the company’s operating system,” Chen said. “If used correctly, it can prevent hackers from exploiting a PC and causing data breaches or other threats. This is necessary for conjunction with the firewall.”

Should you use all three?

There are many advantages to using VPN, firewall and antivirus software together on your business computers, as their functions complement each other.

“Firewall and antivirus software should always be considered a complement to a VPN service,” says Pablo Listingart, founder and owner of ComIT. “They are in no way an adequate substitute for VPN security.”

It is best to have a well-configured firewall with an intuitive interface that allows you to choose which sites to block or allow on your internal network. Add a strong antivirus that can identify and remove all malware from your computer. Get a reliable VPN that allows you to access remote servers without fear of being monitored.

However, technological solutions alone cannot accomplish this task. Your entire team needs to be informed and vigilant about cybersecurity, primarily if you work remotely.


When someone is faced with a choice between a VPN and a firewall, they are usually confused about which of the two to use. Both tools are useful and should be combined to keep your computer safe. VPNs act as a cover while firewalls and antivirus software combat online threats. VPNs act as a second layer of protection, shielding you from malicious websites and other online threats. But they have their differences. Read more about the two types of software to decide which is best for your computer.

Firewalls and antivirus software are essential for protecting your computer, but they don’t all offer the same protection. Most antivirus and firewall software have different policies for these areas. For example, firewalls and antivirus software often only protect your computer from malware and other attacks, while VPNs block websites with harmful content. They also prevent hackers from spying on you. If you are concerned about security, you should check whether the software you use has these features.
