Practical experience is essential in cybersecurity because it shows how you apply knowledge to real tasks. But the available guidance does not prove that experience universally outweighs formal education. The strongest approach is to combine foundations with hands-on practice, then use credentials or work experience to demonstrate what you can do.
What practical experience teaches that study alone may not
Cybersecurity work involves applying concepts in context: investigating a problem, choosing an appropriate response, and learning from feedback. Labs, exercises, competitions, volunteer work, internships, and related employment can give learners opportunities to practise those skills. They can also help a learner show examples of their work rather than relying only on a list of subjects studied.

In a 2018 NIST interview, Rodney Petersen, then director of the National Initiative for Cybersecurity Education (NICE), recommended hands-on learning and said it should ideally be validated through an academic degree, certificate of study, or certification. He also praised experience gained through competitions, volunteer activities, internships, and part-time or full-time work in a related field. These are enduring recommendations, not results from a current employer survey.

Formal courses and degrees can organize foundational knowledge into a sequence of study. Certifications and other credentials can provide a recognizable way to validate learning, depending on the role and employer. NIST’s guidance treats these as possible complements to practical learning, not as substitutes for it or prerequisites that apply universally.
#1 Best Overall
The right balance depends on the cybersecurity role you are pursuing, your existing knowledge, and the opportunities available to you. The sources here do not establish comparative costs, completion times, or employment outcomes for degrees, certifications, labs, or work experience, so there is no evidence-based universal ranking of those routes.
Ways to build practical skills
Home labs and structured practice
NIST’s NICE FAQ recommends practising in an in-home lab. A lab or structured training environment lets you work through tasks and learn from mistakes in a setting intended for practice. NIST does not prescribe a particular setup or hardware. SANS describes formats it uses for practical training, including course labs, capture-the-flag competitions, cyber ranges, exercises, and hands-on skill-validation exams. Those examples describe a provider’s training formats; they do not establish job-placement outcomes.
Rank #2
Competitions and volunteering
Cybersecurity competitions give learners a structured way to tackle challenges. Volunteer work can create opportunities to contribute to a community organization and learn from practical needs. NIST identifies both as ways to gain experience. Choose work that fits your current skills and has clear boundaries, especially when it involves systems or information belonging to others.

Internships, apprenticeships, and related employment
Internships and related jobs can place learning in a workplace context. Apprenticeships can combine structured, mentored hands-on learning with work experience and portable credentials. In a 2024 article, NIST reported, attributing the figures to the U.S. Department of Labor Office of Apprenticeship, nearly 61,000 participants in registered cybersecurity apprenticeship programs in the United States in 2023, a 254% increase over five years. Those figures describe U.S. registered programs and do not show that an apprenticeship guarantees a job.
A practical sequence for aspiring cybersecurity practitioners
- Learn the foundations. Build knowledge relevant to the kind of work you want to do; formal study may help organize that learning.
- Practise safely. Use a home lab or structured environment to apply concepts without treating systems you do not own or have permission to use as practice targets.
- Keep a record of your work. Document projects, the tasks you attempted, what you learned, and how you addressed problems. Make clear what you actually did.
- Seek feedback. Look for mentors, instructors, or experienced practitioners who can help you identify gaps and improve your approach.
- Choose an experience opportunity that fits your level. Consider competitions, community volunteering, internships, apprenticeships, or related employment as appropriate.
- Validate learning where it helps. Consider a degree, certificate, or certification when it fits your goals or the expectations of the roles you are pursuing.
How to choose between learning options
| Option | What it can contribute | What to check |
|---|---|---|
| Formal course or degree | Organized study of foundational concepts; may provide an academic credential. | How well the curriculum fits the target role and whether it includes opportunities to practise. |
| Certification | A credential that can validate learning or skills. | Whether the credential is relevant to the role and what knowledge or practical work it assesses. |
| Lab, competition, or exercise | Practice applying concepts to tasks; may provide feedback or work to discuss. | Whether the environment is suitable for your level and whether the activity reflects your learning goals. |
| Volunteer work, internship, or related job | Experience applying skills in a community or workplace context. | Scope of responsibility, supervision, learning opportunities, and fit with your current ability. |
| Apprenticeship | Can combine mentored structured learning, work experience, and portable credentials. | Program structure, mentorship, credential, and alignment with the work you want to do. |
The guidance establishes these as different ways to learn or demonstrate capability; it does not provide a neutral head-to-head measure of their costs or career outcomes. Compare specific programs and opportunities against your target role rather than assuming one category is best for everyone.

NIST’s NICE guidance supports hands-on learning, home-lab practice, volunteering, and keeping current on threats, while also recognizing education and credentials as ways to validate learning. It does not establish that practical knowledge generally produces better cybersecurity career outcomes than formal education. A 2018 expert interview is useful career guidance, but it is not a current, representative survey of employers.
Kaspersky’s 2024 article reported survey responses in which 46% of surveyed information-security professionals said they had taken additional cyber education courses later in their careers, and about half considered theoretical knowledge from formal education unhelpful to their current job. Those are vendor-reported opinions from a survey, not population-wide findings or proof that practice beats education. They should not be treated as a universal verdict on degrees.
