If you are not sure whether you need a secure firewall for personal or business use, this review is for you. As you may notice, the Internet is enormously fast when it comes to developing technologies. It is easy to miss something new! With the development of the Internet, the need for a firewall as an addition to a robust antivirus emerged. In the review, we offer you the best firewall software that is included in the suites of Avast, Norton, Bitdefender, Webroot, and Panda brands. But first, let us learn what firewall is and which features it offers.

What is a Firewall 

Many people hear the word ‘firewall’ and have no idea what it is. So, a firewall is just a hardware device or software that aims at checking and filtering all the data that comes through the Internet. So, there are two firewall types that you should distinguish: a software firewall and a hardware firewall. Before you choose any of these two, make sure to learn everything about them. If it is a hardware firewall, you should think of it as a router with a range of features. While a software firewall is full-fledged, such firewalls are installed on your devices, and due to this, it can control all the activities of your devices. 

At the same time, however, keep in mind that firewalls are not the same as antivirus – there are considerable differences between these two. Firewalls can stop cut off access to your data, as well as connection, for hackers and malicious software. Thus, it is an excellent example of first-line protection. As for antivirus, it uses different features to scan the system, check all the files, and defend the system against all known cyber threats. Therefore, the firewall is excellent, but it would be better to have a reliable antivirus that already has a firewall feature.

How does a firewall work 

It would help if you programmed your firewall so that it can filter what is coming from the Internet to your network. Below, you can see the primary functions of the firewall:

Packet filtering – this feature aims at the IP packets filtering. In other words, as any of the IP packets headers tries to enter the network, your firewall will inspect it at once. The task of the firewall is to examine such headers and decide on whether to allow it or not.

Proxy Gateways (Application Level Gateways) – additionally, a firewall can check all the application level protocols based on the knowledge about concrete application protocols.

Filtering of the Stateful Packet – the feature that is slightly different from those as mentioned above; this filtering feature stores the connection flows in both directions for all the available IP packets. Besides, it can show you the data about the IP addresses that are connected at the moment.

Below, you will see a list of the essential functions of a firewall for a good buy:

  • VPN – a firewall that comes with a VPN will help you to create a secure infrastructure. Here is how it works: with the help of site-to-site encryption, a reliable VPN makes your IP address anonymous. As a result, no governments, no hackers, or ISP see your Internet connection. They will not also know that you use a VPN server. Thus, a VPN allows you to visit any website you want without anyone spying on you.
  • Packet Filtering – it works perfectly for a small network; a Packet Filtering is put into the network and reminds of routers that work as firewalls. The main task of ut is to check, filter all the packet of information that circulates through your network. Talking about the downsides, the nature of the protection the Packet Filtering offers is not that powerful. Specifically, it will not protect the system from the threats with application-layer vulnerabilities. Yet, it is an excellent variant for small networks within a small company.
  • Stateful Inspection – this type of inspection will be advantageous for you as it analyzes the content and headers of the packets. This examination provides profound protection. 
  • Proxy Server – it is a server that would mask your current Internet/network connection through changing your IP address. Thus, a Proxy Server is like a mediator between your devices and the Internet.
