Beyond the Certs: How to Build a Cyber Security CV That Actually Stands Out

If you ask the internet how to get started in cybersecurity, you will get the same tired advice: “Get your Security+ certification, study the OSI model, and apply for 500 helpdesk jobs.”

But here is the reality of the current job market: if your CV only consists of a list of bullet points saying you are “passionate about tech” alongside a generic certification, you are competing with hundreds of other identical profiles. Hiring managers and senior engineers don’t just want to read what you know—they want to see what you can do.

To land your first role, you need to turn your CV from a flat piece of paper into a dynamic portfolio. Here is how to build practical credibility that proves your technical capability before you ever step foot into an interview room.

1. Weaponize Your CTF Profiles

Almost everyone trying to break into the industry has a TryHackMe or Hack The Box account, but very few people actually use them to their advantage on their CV.

Stop just listing your username. Instead, treat your Capture The Flag (CTF) progression as a verified track record:

  • The “Proof of Work” Section: Create a dedicated section on your CV for technical platforms. List your current global ranking, badge achievements, or specific technical paths you’ve completed (e.g., “Completed the Hack The Box Active Directory Track” or “Ranked in the top 1% globally on TryHackMe”).
  • Deep Dives, Not Just Points: If you completed a gruelling pro-lab or a particularly complex standalone machine, highlight what you learned along the way!

2. Publish Public CTF Walkthroughs (Write-Ups)

Getting a flag is only half the battle. In the real world, a penetration tester or security engineer’s actual product is their report. If you can’t communicate how you broke into a machine, the exploit doesn’t matter.

  • Start a Simple Blog: Set up a quick static site or use Medium to post walkthroughs of retired CTF boxes.
  • Show Your Thinking, Not Just the Exploit: Don’t just paste the exploit payload. Explain how you enumerated the service, why you chose a specific methodology, what failed along the way, and—crucially—how to remediate the vulnerability.
  • The Interview Advantage: When a hiring manager sees a link to a well-written, cleanly formatted technical write-up, they immediately see someone who can write professional documentation.

3. Build Public Security Tooling

You don’t need to be a software engineering wizard to contribute to security tooling.

  • Automate Your Own Workflows: Have a messy string of Bash scripts or a Python script you wrote to automate your enumeration or filter logs during a CTF? Clean it up, comment the code, write a decent README.md file, and push it to GitHub.
  • Contribute to Open Source: Look at open-source security projects on GitHub. Check their “Issues” tab for low-hanging fruit—fixing a bug, updating outdated documentation, or adding a small feature. Having your name attached to a merged pull request on a public repository is an instant CV differentiator.

4. Get Involved in the Local Community

The technical community is smaller than you think, and local involvement carries massive weight.

  • Contribute Content: Don’t just attend meetups—offer to contribute. Write a summary of a local event for a community blog, help test a CTF environment for a local group, or volunteer to give a quick 10-minute lightning talk on a tool you’ve been playing with.
  • Network with Intent: When you meet senior engineers or directors at local hubs like BrumSec Connect, you aren’t just looking for an immediate job. You are building relationships. A referral from an engineer who has chatted with you in person will bypass the automated HR filtering systems entirely.

The Bottom Line: Show, Don’t Tell

The phrase “Highly motivated self-starter” means absolutely nothing on a resume anymore.

A link to a clean GitHub repository, a well-reasoned blog post breaking down a vulnerability, and a solid CTF profile mean everything. It shows you have curiosity, discipline, and the communication skills required to excel in a high-velocity technical field.

Stop collecting badges in secret. Start documenting your journey, publishing your logic, and showing the security world exactly what you are building.
