Firewall Software

Cyber crime is on the rise. Today's digital age is filled with connected technologies, which has only made it easier for cyber criminals to hack into unprotected systems. This calls for reliable and secure network security measures to keep your assets and data safe from hackers.

Firewalls act as the first line of defense against attackers and other external sources of threats such as malware, viruses, and hacking attempts. They can be easily configured to filter outgoing and incoming traffic based on predetermined rules of your network. Firewalls are deployed to fight against these intruders, and firewall management software is required to run a firewall efficiently.

What is firewall software?

Firewall software is used to manage your firewalls efficiently. Firewall software monitors incoming traffic and—based on your network security policy—allows only permitted traffic to access the network. They can also be used to filter traffic based on multiple criteria such as type of data being transmitted, source IP, destination IP, traffic volume, and port number.

Based on deployment, a firewall can be categorized as hardware-based, software-based, or sometimes a combination of both.

Software-based firewall

Software-based firewalls are installed on a computer, server, or router. Software firewalls are preferred by many organizations and enterprises simply due to the ease of deployment, lower initial costs, and fewer restrictions on the number of devices to be protected. They can be installed remotely and require little storage space.

Software-based firewalls also pose some advantages over its counterparts. These are commonly preferred by small and medium-sized businesses due to the expensive nature of hardware firewall options. They can be installed on a single device, and can be updated and reconfigured with ease. They're also compatible with a lot more operating systems, including Windows, MacOS, and Linux. Their only drawback is that they are not as powerful or as effective as hardware-based firewalls when handling huge traffic volumes.

Hardware-based firewall

Hardware-based firewalls, on the other hand, are physical devices that are installed between network elements and connection devices. These tend to have a lot more features, better performance than software-based firewalls, and are preferred by bigger enterprises that require a higher level of security for their devices and users. Hardware firewalls also make it easier to exercise granular control, but they require dedicated staff to maintain it.

Hardware-based firewalls are available in multiple forms—such as standalone devices, rack-mounted units, as well as in combination with other devices—to offer advanced security features such as intrusion detection, intrusion prevention, VPN, and so on. Hardware-based firewalls are largely preferred for their ability to handle large traffic volume, which is required for large organizations, enterprises, and MSSPs.

Hardware vs Software firewall


Hardware firewall Software Firewall
More expensive Cheaper
Dedicated hardware device Can be installed on computers, servers, routers, etc.
Complex configuration and management Can be easy to configure and update
Restricted by device capability Easily scalable
Has more advanced security features Contains limited advanced features
Less susceptible to attacks and vulnerabilities Compromised by software vulnerabilities such as malware and viruses


Why is firewall software essential?

  • Protection against cyberattacks: Threat actors employ various tactics like malware, phishing, and hacking to infiltrate your network. Firewalls act as the first line of defense, detecting and blocking these threats before they can cause damage.
  • Data security and privacy: Your data is your most important asset. Firewalls prevent unauthorized access and theft, keeping your confidential information safe from unauthorized access.
  • Comply with regulatory mandates: Many industries have strict data security regulations like GDPR, NIST, SOX etc. Firewalls play a crucial role in achieving compliance by enforcing necessary security protocols.
  • Reduced risk of malware and viruses: Firewalls can filter out malicious software before it infects your devices, protecting your systems from potential harm.
  • Improved overall network performance: By controlling traffic flow and blocking unwanted data packets and usage attempts, firewalls can optimize network performance and improve user experience.

Advantages of using firewall software:

A Network firewall software gives you more insights into the performance of your firewalls and helps you make informed decision when a security breach occurs. Here are some of the advantages of utilizing firewall software:

  • Real-time visibility: Gain real-time visibility into the traffic flowing through the firewall. This helps admins to identify security threats quickly.
  • Performance monitoring: Understand your firewall's performance and the factors that can affect its efficiency such as misconfiguration, high traffic, etc.
  • Alerting and reporting: Ensure no suspicious event goes unnoticed thanks to real-time alerting. Get a sense of the state of your network's security with a variety of reports.
  • Streamline firewall management: Automate the task of monitoring the firewall, allowing network admins to focus their time on other important tasks.

Choosing the right firewall software

With the barrage of firewall monitoring software available in the market, selecting the right solution can be overwhelming. Here are some of the factors to consider:

  • Budget and licensing: Personal firewalls differ from enterprise-level solutions in pricing and license. Consider the upfront cost in addition to ongoing maintenance and support, understand the licensing model and choose one that aligns with your specific requirements.
  • Ease of use: Look for a user-friendly interface that makes configuration and management simple, even for non-technical users. Prefer tools that offer a intuitive controls and simplified dashboard.
  • Compatibility: Ensure the firewall software is compatible with your operating system, firewall device and is capable of meeting the reporting and other audit needs of your organization.
  • Advanced features: Some firewalls offer additional features like intrusion detection, intrusion prevention, VPN management, log analytics, compliance management etc. Choose one that provides the functionalities you need.
  • Scalability: Consider future needs and choose a firewall software that can accommodate your business needs as it scales. Ensure it can handle managing additional firewalls and the increase in traffic.
