July 2025 - Cyber Security Career Preparation

In a competitive field like cyber security, a strong CV isn’t enough. Employers and recruiters want proof that you can do the work—not just say you can. That’s where a professional portfolio comes in.

Think of your portfolio as your digital testimony—a space where your skills, experience, and growth are on full display. Done right, it will not only help you stand out but also serve as a tool for reflection on how your talents can be used for good.

What Is a Cyber Security Portfolio?

A cyber security portfolio is a curated collection of your projects, labs, certifications, write-ups, and tools that demonstrates your hands-on experience and learning journey. It might be hosted as a personal website, GitHub repository, or digital notebook (like Notion or Obsidian).

Unlike a CV, which just tells, a portfolio shows.

What to Include

Hands-on Projects
Include examples such as:
- Vulnerability scans you’ve performed (e.g., using Nmap or Nessus)
- CTF (Capture the Flag) write-ups or challenges you’ve solved
- Scripts you’ve written in Python or Bash
- Home lab configurations or network diagrams

Be mindful of ethics—never post details of real systems or sensitive data.

Certifications and Courses
Don’t just list certificates—write about what you learned, how you applied it, and why it matters. This turns a badge into a story.
Blogs or Write-ups
Even simple posts about what you’ve learned show communication skills and clarity of thought—both prized in security roles.

“Let your light shine before others, that they may see your good deeds and glorify your Father in heaven.”— Matthew 5:16

Don’t hide your growth. Share what you’re learning. It helps others—and glorifies God.

Version Control and Documentation
Use GitHub to share your code or documentation. Even if it’s small, it shows you’re practicing real-world collaboration tools.
Your Faith and Values (Optional)
If you feel led, include a short section or tagline that reflects your desire to work with integrity, purpose, and ethics grounded in your faith. This can gently show employers what motivates you—without preaching.

Building It Step-by-Step

Start Small: You don’t need 10 perfect projects. Begin with one lab or script and build from there.
Stay Consistent: Update regularly. Even a small commit every week shows growth.
Use Templates or Examples: Look at GitHub portfolios or websites of professionals for inspiration.
Keep It Honest: Don’t exaggerate or include copied work. Humility and truth go further than polish.

Bonus Tips for Aspiring Professionals

Buy a domain name and host your portfolio site. It shows professionalism.
Include a résumé download link.
Add a contact form or email so people can reach you.
Link your LinkedIn and GitHub for easy access.

God and Your Portfolio

As Christians, we aim for excellence not for recognition, but as an act of worship and stewardship.

“Whatever you do, work at it with all your heart, as working for the Lord, not for human masters.”— Colossians 3:23

A well-crafted portfolio doesn’t boast—it testifies. It tells the world that you care about doing the job right, learning continually, and using your gifts to make the digital world safer and more just.
