Cybersecurity vs Computer Science: Which One to Choose in 2025?

Every time you send an email, stream a movie or shop online, you are relying on the work of computer scientists and cyber security experts.

These fields are so deeply ingrained in our lives that it's hard to imagine a world without the advancements brought by computer science, which power the technology we use every day. Equally important is the role of cyber security, ensuring that the vast amount of data we produce is safe and protected from threats. 

Both fields are crucial. But if you're deciding on a major, which one should you choose? Keep reading to discover the key differences between computer science vs. cyber security and find out which might be the best fit for you.

Key Takeaways

• Computer science covers the broad foundations of computing, from programming to AI, while cyber security focuses specifically on protecting systems and data from attacks.
•  A degree in computer science leads to careers like software development and data analysis, while a degree in cyber security opens doors to roles like ethical hacking and network protection.
• Whether you choose computer science or cyber security, UND offers programs that combine theoretical knowledge and hands-on experience to prepare you for a high-demand, future-proof career.

What is Computer Science?

Computer science is essentially the backbone of everything tech-related. Although most people associate it with only code writing—though that's a big part of it—computer science is also about understanding the theory behind computation, designing efficient systems, and exploring exciting areas like artificial intelligence, machine learning, and data science.

What is Cyber Security?

Cyber security, on the other hand, is all about reducing the risk of cyberattacks for individuals and organizations. At its core, it's the practice of protecting the devices we use every day—like smartphones, laptops, tablets, and computers—as well as the online services we rely on from being hacked, damaged, or stolen and ensure that only the right people have access to it.

What is the Difference Between Computer Science and Cyber Security?

The difference between computer science and cyber security, at its simplest, is that one is broad and foundational, touching on everything related to computing, while the other is specialized and laser-focused on protecting systems and data. 

But of course, it's not just that straightforward because once you start considering things like curriculum structure, credit hour requirements, the kinds of job opportunities each one leads to, and even just how challenging one might be compared to the other, you quickly realize that while they share common ground, they each carve out their own distinct paths.

Head-to-head Comparison

The main differences, as you will see in the table below, revolve around their focus and career opportunities. 

Keep in mind that these specifics don't make one better than the other—it all depends on your career aspirations. Our goal is simply to help you understand the distinctions so you can make an informed decision.

Important Certifications for Cyber Security and Computer Science

Having a degree is a great foundation, but certifications can set you apart, proving to employers that you have specialized skills and up-to-date knowledge in your field. 

Whether you're pursuing computer science or trying to get into cyber security, earning the right certifications can increase job opportunities and even lead to higher salaries. While some certifications are more technical and role-specific, others focus on broader industry standards, making them valuable no matter where you are in your career.

Here are some of the most important certifications you can pursue to increase your chances of success:

Keep in mind that these certifications aren't always required. Check the specific work requirements before committing to any of them.

Are Degrees in Cyber Security and Computer Science Worth It?

Whether a degree in computer science or cyber security is worth it depends on what you're looking for because while both open doors to solid careers with good salaries and plenty of job opportunities, the real question is whether the time, effort, and cost of getting that degree align with what you actually want to do, how you prefer to learn, and what kind of work excites you enough to keep doing it for years to come.

For some, the structured learning, networking opportunities, and credibility that come with a degree make it a no-brainer, especially since employers still value formal education. Still, for others, especially in tech, where skills and hands-on experience can sometimes outweigh credentials, alternative paths like certifications, boot camps, or self-study might make more sense, particularly if the goal is to get into the workforce quickly without spending much time in school.

And then there's the ever-changing job market—both fields are in high demand, with cyber security arguably growing even faster due to increasing cyber threats, but at the same time, tech is one of those industries where rapid change is the norm, meaning what's valuable today might shift in a few years, so the worth of a degree isn't just about whether it gets you a job now, but whether it gives you a strong enough foundation to adapt, grow, and stay relevant in the long run.

However, one thing is certain—technology is our future. If you're considering a degree in cyber security or computer science, you're making a smart choice. With the growing demand for tech professionals, your skills will be in high demand, opening doors to exciting and well-paying opportunities.
