16 Firewall Engineer Skills for Your Career and Resume

Learn about the most important Firewall Engineer skills, how you can utilize them in the workplace, and what to list on your resume.

A firewall engineer is responsible for designing, implementing and maintaining network security systems. Firewall engineers need to have a strong understanding of network security principles and be able to apply them to real-world scenarios. They must also be able to troubleshoot and resolve complex technical problems. If you’re interested in becoming a firewall engineer, it’s important to understand the skills that are necessary for this position.


Firewall engineers use Fortinet, a software program that allows them to create and manage firewalls. This skill is necessary for the position because it’s common for companies to use this software when creating their own firewalls. Firewall engineers need to know how to use Fortinet in order to be successful in their careers.

Analytical Skills

Firewall engineers use analytical skills to analyze data and information about the firewall system they’re designing. They also use these skills when testing their firewalls to ensure that they work as intended. Firewall engineers need to be able to interpret data from tests, evaluate the results and make changes if necessary.


Firewall engineers use IPTables, a software program that allows them to create rules for incoming and outgoing data. These rules are known as firewall policies, which can be used to block malicious traffic from entering the network or allow only certain types of information to pass through it. Firewall engineers also use IPTables when creating virtual private networks (VPNs), which are secure connections between two computers over the internet.


Firewall engineers use pfSense, a software firewall that can be installed on physical hardware. This allows them to create their own firewalls and customize the features of those systems. Having knowledge of pfSense can help you design your own firewalls and troubleshoot any issues with existing ones. It also gives you more control over how your network operates, which can make it easier for you to monitor and maintain it.


Firewall engineers use WatchGuard, a software program that allows them to monitor and control the firewall system of an organization. They need to know how to operate this software so they can troubleshoot any issues with it or make changes to improve its performance. Firewall engineers also use WatchGuard when testing new firewalls to ensure they are working properly.

Cisco ASA

Firewall engineers use Cisco’s Adaptive Security Appliance, or ASA, to build and maintain firewalls. This software is used by many companies as a security measure for their networks. Firewall engineers need to know how to configure the firewall software and troubleshoot any issues that may arise with it.

Check Point

Firewall engineers use check point, a software program that allows them to test their firewall designs for vulnerabilities. This skill requires knowledge of computer programming languages and the ability to create programs that simulate real-world conditions. Firewall engineers may also need to know how to interpret results from these tests in order to make adjustments to their designs.

Attention to Detail

Firewall engineers must be able to follow instructions precisely when designing firewalls. They need to ensure that the firewall is built according to industry standards and regulations, which may require them to use specific types of hardware or software. Firewall engineers also need to pay attention to details in order to identify potential vulnerabilities within a system.

Problem Solving Skills

Firewall engineers use problem-solving skills to troubleshoot issues with existing firewalls and develop new firewall models. They may also apply these skills when working with clients to determine the best security measures for their company’s needs. Firewall engineers often work with other IT professionals, so they need to be able to communicate effectively and collaborate on projects.


Firewall engineers use creativity to develop new methods for protecting computer systems. They may design unique firewall software that uses different techniques than existing programs, or they might create a system that combines several types of firewalls into one product. Firewall engineers also use creativity when designing security protocols and procedures. For example, if an organization has a high risk of cyberattacks, the engineer may suggest using multiple layers of protection instead of relying on just one type of firewall.


Firewall engineers use their knowledge of firewalls to design and implement security systems for businesses. They need to understand how different types of firewalls work, including software-based firewalls that run on a computer or server and hardware-based firewalls that include physical devices like routers. Firewall engineers also need to know the various protocols used by firewalls so they can configure them correctly.

Organizational Skills

Firewall engineers must be able to organize their work and keep track of files, documents and other resources. This is especially important when working with a team on a project because it ensures everyone has the information they need to do their job well. It’s also helpful for keeping track of your own work so you can find what you need quickly if someone else needs to review or approve it.

Juniper SRX

Firewall engineers use Juniper SRX to configure and maintain firewalls. This software is a type of security system that protects computer networks from outside threats. Firewall engineers need to know how to install, operate and troubleshoot the firewall so they can ensure it’s working properly. They also need to be able to update the firewall when necessary to keep it secure.


Barracuda is a brand of firewall software that can be used to protect computer networks. Firewall engineers need to know how to use this and other types of security software so they can design firewalls that are effective at protecting data from unauthorized access. They also need to understand the different types of network security protocols, such as Intrusion Detection System (IDS) or Distributed Denial-of-Service (DDoS), in order to build an appropriate defense system for their clients’ needs.

Time Management

Firewall engineers often work with strict deadlines, so time management skills are important for this career. You may need to meet project goals and complete tasks by certain dates, so it’s important to be punctual and plan your day accordingly. For example, if you know you have a meeting at 2 p.m., you should start working on the task before that meeting by 11 a.m.

Palo Alto Networks

Firewall engineers use their knowledge of network security to design and implement firewalls, which are systems that protect computer networks from cyber threats. Understanding the different types of firewall technologies can help you develop your skills as a firewall engineer. Palo Alto Networks is one example of a type of firewall technology.

How Can I Learn These Firewall Engineer Skills?

There are a few ways to learn the skills necessary to become a firewall engineer. One way is to take an online course or tutorial that covers the basics of networking and firewalls. Another way is to read books or articles on the subject. Finally, you can also attend conferences or seminars that focus on firewall engineering.
