What is a Firewall?

When surfing the internet, there are many dangers in the form of malware and hackers. They all are trying to gain access to your computer. Just like a security fence protects your home from burglars and intruders, a firewall keeps cyber criminals from penetrating your computer systems. A firewall acts as a defense system for your local computer and protects it from viruses, Trojan, and other malware. It can take the form of software such as a security program or hardware such as a physical router. The function of both remains the same, i.e., scanning of every network traffic. These make sure that the incoming traffic is not blacklisted or contains anything malcious.

An introduction to a hardware firewall

A hardware firewall is a physical piece of firewall appliance that offers security from Cyber threats. This device works as a gatekeeper and protects the network and endpoints from viruses and other threats. Unlike a software firewall, it does not use the computer’s software or RAM, or CPU for the processes. The hardware firewall is usually put between the server and the external network through a cable to filter the total traffic that comes into and goes out of the network. The most significant feature of a hardware firewall is that it can protect all the systems connected to it through a single network. 

Standard features of a hardware firewall include:

  1. Control of all devices through a single network.
  2. Timely up-gradation to keep the systems secure.
  3. Preventing threats from reaching the internal structures.
  4. Separate operating system for better security.
  5. Constant protection till someone chooses to turn it off. 

Five reasons why a business needs a hardware firewall? 

The hardware firewalls are physical appliances that can be fixed with your network and offer you the ultimate enterprise-grade security from cyber threats. Business, whether small or large, needs to have fully functional firewall security. Here are some of the reasons why your business needs a hardware firewall.

  1. Managing traffic: Using a hardware firewall helps in managing the traffic. You can control what should reach your network and what should not.
  2. Prevention of Intrusion: The firewall scans all the packets arriving into the system network. It checks for malicious files and takes appropriate action against them.
  3. Antispyware and Antivirus: We know that the firewall works against viruses that tend to corrupt the files. Except this, the firewall also works against the spyware that might enter the network and spy on the company’s confidential information.
  4. Running a VPN: A Virtual Private Network is one of the essential requirements of every company. It keeps the network and systems secure. The use of a hardware firewall provides you with another benefit of running a VPN, making it cost-effective.
  5. Device Control: The devices that a company uses include desktops, mobiles, and tablets, etc. All the devices nowadays are connected to Cloud. A firewall helps in managing the data going in and out of the devices wherever they go.
