How should you write a network security engineer resume that lands jobs

There is a staggering amount of technologies working together to ensure a network and the data it transmits are protected.

Your networking skills stand at the top of the list - setting up servers, managing routers and switches, implementing TCP/IP protocols, etc.

Include any of the following network security proficiencies in your resume:

  • Access control
  • Antivirus and antimalware software
  • Data loss prevention
  • Email security
  • Firewalls
  • SIEM - Security information and event management
  • Web, Wireless and Mobile security

Each is important, but what does the job description say?

If the employer is using predominantly Cisco networking hardware and software, that must be the most prominent section in your Security Engineer resume.

Make sure you list your proficiency with Cisco security technology like:

  • Cisco ASA
  • Meraki MX
  • Firepower

That said, your experience with Palo Alto Cortex or FireEye solutions is also important. More often than not you will need to mix and match different technologies and vendors when managing the security of a given network.

Focus on how you used these security products to improve the efficiency and reliability of the entire network.

  • Did you reduce network delays from security systems by 13%?
  • Cut down security monitoring time by automating parts of the system?
  • How did you solve vulnerabilities in 3rd party software used by the company?

Your technical skills are indispensable. However, you will frequently collaborate with other departments. Soft skills like communication, organization and teamwork are sought for.

That’s a lot of information to squeeze into your Network Security Engineer resume. It’s essential that you start with an effective resume layout.

What’s the proper Network Security Engineer resume format?

There are three common layouts found in every resume out there:

  • Reverse chronological - this layout focuses on work experience and education in a timeline format.
  • Functional - this layout displays your skills and competencies up top, focusing on your abilities instead of past experience.
  • Hybrid - this layout is a mix of the two other, making sure all skills and experience relevant to the job offer are positioned at the top.

For a Network Security Engineer resume, the hybrid layout is recommended, as it provides a quick rundown of your professional abilities, coupled with experience.

It is also important to format your resume well, so that it is more appealing and projects your professionalims and attention to detail. Pay close attention to the resume font, colour scheme and the use of margins and icons.

Employers are interested in candidates who understand how their network works and can implement effective security measures.

Regardless of which layout you choose, there are several resume sections you must absolutely include in your network security resume.

Here's what employers want to see in a network security engineer resume

  • The resume header must clearly state who you are and what you do
  • A good resume summary grabs the attention and keeps the recruiter reading
  • Convincing technical and soft skills help dial you in as the right applicant
  • Work experience creates an impact and brings your value proposition up front
  • Industry accepted certification and education is essential to get the job

Here’s how to write a Network Security Engineer resume header

The resume header is often taken for granted. There are just so many ways you can write your name and contact info right?


In fact, most Network Security Engineers don’t use the full potential of the header section. Not to mention, some don't even add a photo and a LinkedIn account. Let's review the following resume samples and see how we can improve yours.

Okay, what are the differences:

  • The second resume example includes way more information about the applicant.
  • The job title is very descriptive and gives a sense of the applicant’s skills early on.
  • There is a GitHub portfolio linked in the second example. GitHub is the go-to community for all IT professionals, regardless if they are programmers or not.

A recruiter will scan your resume for keywords related to the job. Adding the required networking technologies, as found in the specific job offer, at the top of your resume will keep them reading.

The best way to make your Network Security Engineer summary (examples included)

So far, so good, they are reading your Network Security Engineer professional summary.

This is the make or break section in your entire resume. If you don’t make an impact now, you’re headed for the bin.

Construct your resume summary around your experience with the technologies and responsibilities listed in the job description.

  • Which networking systems are they working with - Cisco, Azure, Aruba?
  • Is the position calling for an all-around cybersecurity expert or, say, a specialist in email security to join a team of Network Security Engineers?

Your cyber security resume objective should be specific and portrait you as the perfect candidate for the job.

2 network security resume summary examples

I’m a network security engineer. On my last job, I designed and configured network security architecture at the company. I monitored and maintained a network of 100 computers at the company office.

The summary above is far too vague. The only piece of information provided is the size of the network.

There is no mention of the security system installed, the networking technology used or the type of threats and vulnerabilities which the engineer had to resolve on a daily basis.

Network Security Engineer for 3 years. Professional knowledge of networking and network security technologies, as well as data management and security. Worked for a medium-sized company where I was in charge of securing a network of 100 computers using predominantly Cisco hardware and software solutions.

This summary is a bit better. It mentions the years of experience and the technology this candidate is proficient in, as well as the scale of the network he was working on.

It could still be made better by eliminating the use of “ I “ and including more specific information about skills and certifications.

Cisco Certified Network Professional with 5 years of experience designing, launching and maintaining network security systems for FinTech businesses and startups. Highly proficient in Cisco networking hardware and software (ASA, Firepower), data security and integrity, firewall management and penetration testing (Metasploit). Has managed various network sizes and maintained access control using RADIUS.

Now, this is a great Network Security Engineer summary. It lists the applicant’s experience, their CCNP certification, knowledge of various security technologies and networking hardware.

Last but not least, it mentions the industry they worked with. Financial companies are magnets for hackers. If you’re able to successfully defend a cryptocurrency startup’s servers, you have something to brag about.

What should your network security resume experience section look like?

If a recruiter is reading the experience section on your Network Security Engineer resume, you’ve likely passed at least one round of sorting.

The worst thing you can do now is type out a generic job description and bore them to death.

Yes, you are expected to have managed computer networks and implemented antivirus software, firewalls, encryption protocols etc.

  • But which ones? At what scale?
  • What challenges you’ve encountered?
  • What unique solutions you have created?
  • What results do you have to show for yourself?

You must be specific!

Look at the job description and extract network security technologies and skills the employer is looking for. Tailor your work experience around them to make yourself more relevant to the recruiter.

Add more skills and proficiencies to fill in the gaps. Speaking of gaps if you have gaps in the emmployment, here is how to explain it on your resume.

Don’t forget about the soft skills. You will be communicating and collaborating with other departments, so you must be a problem solver, team player and good organizer.

Let’s analyze some real-world work experience samples.

Network security engineer resume experience examples.

Network Security Engineer
JM Software Solutions
San Francisco, CA
  • Managed and maintained company’s computer network
  • Implemented network security software and monitored integrity daily
  • Evaluated threats and vulnerabilities and proposed solutions
  • Collaborated with other departments as needed

This work experience description is bland and vague. It’s nothing more than a boring description of what a network security engineer does.

It’s true, however, it doesn’t provide any specific information about the job.

  • Was type of network - Cisco, HPE, Juniper?
  • What security software and protocols were implemented?
  • Which vulnerabilities were solved and how?
Network Security Engineer
JM Software Solutions
San Francisco, CA
  • Managed a medium-sized office network of 5 Cisco routers, 30 switches and more than 200 individual computers
  • Configured and managed Cisco Umbrella, Email security and Web security to prevent employees interacting with malicious content through the company network
  • Configured Firepower NGFW to block attacks and intrusion attempts
  • Collaborated with network engineers and application developers to optimize the network and remove vulnerabilities in minimal time frames.

This work experience is much better. The applicant speaks of specific hardware and software technologies they used on a daily basis and the responsibilities they had.

If the hiring company works predominantly with Cisco products, this candidate has super relevant work experience already.

That said, it can be even better. Let’s look at a few more cyber security resume examples.

Cyber security engineer resume experience examples

Cyber Security Engineer
American Express
New York City
  • Consulted cyber security in a financial services firm
  • Performed penetration testing and reported to higher management
  • Optimized security system performance and reduced load on the network
  • Coordinated with network engineers for implementing solutions

Again, this work experience is generic and doesn’t offer any insight about what was actually done during the project.

The applicant doesn’t demonstrate proficiency in any technology, hardware or software.

They may be an excellent cybersecurity expert, but their experience is poorly explained and such a resume may not reach an interview stage.

Let’s see how we can fix it in the next cyber security sample resume.

Cyber Security Engineer
American Express
New York City
  • Developed new network security roadmap for a branch of a world-leading financial services company
  • Performed pentesting Nmapper, Wireshark and the Metasploit Framework. Created a full threat and vulnerabilities report for all assets of the company network
  • Collaborated with the network engineers to optimize and simplify the network, removing redundant hardware and streamlining flow of information.
  • Overall work resulted in 9% improvement in network efficiency, while nearly doubling the effective security measures active throughout the network.

Now this is a well-crafted experience section. The applicant mentions several software products they used for penetration testing, giving a hint of what that vulnerabilities report looked like.

They state what improvements they implemented and how they improved the performance of the network - something which the employer will certainly want to know.
