Difference between hardware and software firewall
It is a prevalent misperception that firewalls are only necessary for large or multinational corporations. The rapid evolution of cyber threats has made the deployment of a firewall mandatory for businesses of all sizes. The recent pandemic has also contributed to organizations shifting toward a cloud-first or digital cyber security strategy.
A firewall can do much more than protect your network from cyber criminals and hackers. It collects security data on prevalent vulnerabilities and automates the defenses. It also assists businesses in maintaining compliance standards and resolving networking issues that influence productivity. Lastly, a strong firewall will limit access to potentially unsafe connections to unauthorized websites using your network.
Hardware firewall
A hardware firewall is physical hardware positioned between network elements and connected devices to filter traffic for cyber threats to the network or devices. It is often known as a network or next-generation firewall, and secures an enterprise's network gateways.
One of the most significant advantages of a hardware firewall is the ability to filter out unauthorized or questionable users based on traffic analysis. Hardware firewalls are most commonly employed by organizations that require a higher level of protection for all devices and users and safe access to vital company data in any setting. Some firms select this method because they have highly competent IT experts to administrate the firewall and hardware.
Software firewall
A software firewall is installed on the server and acts as a protective shield for other computers connected to the network. It can monitor incoming and outgoing traffic for possible danger or questionable user behavior, which makes establishing security controls much easier, faster, and more adaptable. It integrates with a wide range of technology security solutions to provide more robust and cohesive security for organizations of all sizes.
For various reasons, these firewalls are quickly becoming the preferred solution. Enterprises appreciate the reduced starting cost and the lack of constraints on the number of devices to be secured. This type of firewall is especially important because it takes up little space and can be installed remotely on various devices. It differs greatly from its counterpart, the hardware firewall, which has several distinctive features.
Difference
Attributes | Hardware Firewall | Software Firewall |
Broad vs. granular protection | Protects the whole network | Provides granular protection |
Configuration | Complex | Simple and easy |
Cost | More expensive as it requires hardware and skilled IT experts | Deployment and maintenance are less expensive |
Flexibility | Less flexible as compared to the software firewall | Flexible as it has the liberty to choose which application has to be installed |
Performance | Does not affect the performance of the system | Slows down the system |
Requirement | Need to install on a single hardware device | Required to install on every single device |
Blocking | Can block a domain or website | Can block content based on keywords |
Conclusion
It is tricky to install a hardware or software firewall. The organization's needs and situation determine the choice between the two. A hardware firewall may be preferable for information security in medium to large organizations with an extensive network of computers.
However, hardware firewalls deployed in a network are vulnerable to some vulnerabilities. Therefore, experts advise installing hardware and software for a high level of security within the enterprise.
