San Francisco, CA


Dear Hiring Manager,

I am writing to express my interest in contributing to your esteemed team as a Network Security Engineer. I have closely followed your company's growth and am impressed by your commitment to innovation and excellence in the field of networking solutions.

One of my pivotal achievements was while working at Hudson PLC, where I oversaw the installation of Cisco TX 9000 series at Landlease. I spearheaded a scripting initiative that mitigated errors and accelerated delivery timelines by 70%, positively impacting project outcomes. Moreover, I was instrumental in generating $225K in managed services revenue by optimizing network security frameworks for various clients.

I am eager to bring my technical acumen and proven track record to your organization and am confident in my ability to contribute meaningfully to your team's success. I am looking forward to discussing how my skills and insights can align with the strategies and goals of your company.

Sincerely, MARCUS HALL Network Security Engineer
What makes this cover letter good:

  • Highlighting specific achievements with quantifiable outcomes, such as "spearheaded a scripting initiative that mitigated errors and accelerated delivery timelines by 70%," shows the candidate's ability to deliver tangible improvements in efficiency and performance.
  • Mentioning relevant industry experiences, like overseeing the installation of Cisco TX 9000 series, demonstrates familiarity with industry-standard technologies and projects, positioning the candidate as an experienced and knowledgeable professional.
  • Discussing financial impact, for instance, "generating $225K in managed services revenue," underscores the candidate's ability to contribute to the company's financial goals, which is always a paramount concern for any role with a direct influence on business growth and client services.
  • Expressing familiarity with the company's culture and showing enthusiasm for contributing to the company's strategic goals, as done in the closing paragraph, helps to establish a personal connection and a shared vision for success.

What are the basics of the design or format of your network security engineer cover letter?

To start, here's a reminder for you: the Applicant Tracker System (or software that is used to assess candidate profiles), won't be reading your network security engineer cover letter.

Recruiters enjoy reading network security engineer cover letters with a standardized format that uses:

  • the same font as the resume (e.g. modern ones like Raleway or Volkhov are prefered over the clichéd Times New Roman or Arial);
  • single spacing to keep the content concise and organized (this is all ready for you in our cover letter templates);
  • a one-inch margin to wrap around the text, like in our cover letter builder;
  • PDF as a file format, as it allows your design (and visual element) to stay the same.

Finally, we can't go on without mentioning the key sections of your network security engineer cover letter.

In the top one-third, make sure to include a header (with your contact information, name, role, and date), a salutation, and an introduction.

Next, follows the heart and soul of your network security engineer cover letter or its body.

End your network security engineer cover letter with a closing paragraph and, if you wish, a signature.

Key qualities recruiters search for in a candidate’s cover letter

  • In-depth understanding of network security protocols and best practices, including VPNs, firewalls, intrusion detection/prevention systems, and encryption technologies.
  • Experience with network security tools and software such as SIEM (Security Information and Event Management), vulnerability scanners, and network monitoring solutions.
  • Strong analytical and problem-solving skills for effectively identifying vulnerabilities, investigating security breaches, and developing strategies to prevent future threats.
  • Knowledge of compliance standards and regulations such as PCI-DSS, HIPAA, GDPR, and NIST frameworks to ensure adherence to legal and organizational security requirements.
  • Proven ability to design, implement, and manage secure network infrastructures tailored to organizational needs, including secure remote access and BYOD policies.
  • Excellent communication and collaboration skills to work with IT teams, stakeholders, and vendors, and to clearly document and explain security measures and protocols.

How to greet recruiters in your network security engineer cover letter salutation

As the saying goes, "You never get a second chance to make a first impression."

Write your network security engineer cover letter salutation to be more personalized to the actual hiring manager, who is set to assess your profile by:

  • greeting them on a first-name basis, if you have previously communicated with them (e.g. "Dear Sam,");
  • using their last name, if you have more formal communication or haven't spoken to them (e.g. "Dear Mr. Harrows" or "Dear Ms. Marshall");
  • writing "Dear HR Team" or "Dear Hiring Manager", if you have no clue about who's recruiting for the role.

Search on LinkedIn, Google, or the company website to find information as to the recruiter's name.

In any case, avoid the impersonal "Dear Sir or Madam".

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Company Name] Team,
  • Dear [Department Name] Department,
  • Dear [Specific Job Title],
  • Dear [Mr./Mrs./Ms./Dr.] [Last Name],
  • Dear Search Committee,

Get creative with your network security engineer cover letter introduction

Recruiters are going to assess plenty of candidate profiles for the role. Thus, anything you do to stand out will win you brownie points.

Use your network security engineer cover letter introduction to share something memorable about your experience.

But before you go down the rabbit hole of creativity and humor, align your message with the company culture.

For example, if you are applying for a role in some startup, use those first two sentences to tell a funny story (about your experience) to quickly connect with the recruiter.

Intro Paragraph
I am eager to leverage my expertise in securing complex network infrastructures to foster innovative cybersecurity solutions at XYZ Corp, a pioneer in harnessing cutting-edge technology to protect digital assets. My track record in threat mitigation and passion for continuous learning align perfectly with the forward-thinking approach that XYZ Corp is renowned for.

What comes next: your network security engineer cover letter middle paragraphs

In the next three to six paragraphs (or the body of your network security engineer cover letter) you have to prove your unique value.

Most candidates tend to mess up at this stage. They tend to just copy-paste information from their resume.

That's one big no-no.

Remember that when writing your network security engineer cover letter, it has to be personalized. And, your ultimate aim is to catch the recruiter's eye.

So, look back on key job requirements and write down a list that includes the ones you cover.

Next, select just one key achievement from your professional (or personal) history that meets those advert keywords.

Narrate a story around how you've grown your skill set and knowledge. Also, aim to show the unique understanding or soft skills you bring about, thanks to your past success.

Body Paragraph
At my previous position, I spearheaded the development of an intrusion detection system that reduced network breaches by 45% within the first year. Harnessing my in-depth knowledge of network protocols and cybersecurity frameworks, I tailored the system to preemptively identify and neutralize threats, which cut down incident response times by 30%. This not only fortified our security posture but also streamlined our operational efficiency, making it a win-win for the company.

Time to wrap up your network security engineer cover letter

Writing the closing paragraph of your network security engineer cover letter is just as important as the salutation.

You have to make it personalized to the job advert and recruiter.

Experienced professionals advise candidates to end with a request or reminder for follow-up. Write that you're grateful for the opportunity, and, at the same time, hint that you're available for the next steps of the process.

Otherwise, you could also conclude your network security engineer cover letter by facing the future. How do you see yourself, as part of the team? In particular, how would you settle in your new role in the first six months to a year?

Closing Paragraph
I eagerly anticipate the opportunity to discuss how my skills align with the team's goals. Please feel free to reach out to schedule an interview.

Keep this in mind when writing your zero experience network security engineer cover letter

Even though you may not have any professional experience, your network security engineer cover letter should focus on your value.

As a candidate for the particular role, what sort of skills do you bring about? Perhaps you're an apt leader and communicator, or have the ability to analyze situations from different perspectives.

Select one key achievement from your life, outside work, and narrate a story that sells your abilities in the best light.

If you really can't think of any relevant success, you could also paint the picture of how you see your professional future developing in the next five years, as part of the company.

Key takeaways

Summarizing the most important aspects in writing your network security engineer cover letter, remember to:

  • Create a personalized network security engineer cover letter for each role you apply for, that includes the recruiter's name in the salutation;
  • Format your network security engineer cover letter with single-spacing, one-inch margins, and a modern, yet ATS-friendly font;
  • Always start off your network security engineer cover letter with two sentences that reflect what is most important about your application;
  • Your network security engineer cover letter body should feature your biggest accomplishments and the job-relevant skills it has taught you;
  • Instead of opting for the "Sincerely yours" ending, close your network security engineer cover letter with a nod to the future with what you aim to achieve in this potential role.
