Fortunately, online learning platforms offer flexible and affordable free cyber security courses with certificates.
But with so many online learning platforms out there, it’s not always easy to decide which one is right for you. In this article, we’ll compare Alison and Udemy, two popular platforms, to help you choose the best option for gaining cyber security certifications, whether you’re a beginner or a professional.
Whether you’re budget-conscious, just starting your career, or switching to a fast-growing field, this guide will help you choose the right cyber security certifications for beginners with confidence.
Why Cyber Security Is a Top Career in 2025
The global shift towards digitisation has created an urgent need for skilled cyber security professionals. Statistics show that there are 2,200 cyber attacks every day, with one happening every 39 seconds. Businesses, governments, and individuals have become more open to sophisticated cyber attacks, including phishing, ransomware, and data breaches. Cyber crime is projected to cost the world $23 trillion by 2027.
The numbers don’t lie. It’s clear that cyber security skills are not only valuable, they’re a gateway to a future-proof career, and it is necessary for businesses and individuals alike to be educated on this. Cyber security roles like Information Security Analysts, Ethical Hackers, and Computer Security Specialists offer competitive salaries, job security, and growth opportunities, especially in the new digital era.
Factors behind the growing demand for cyber security skills:
- Increased cyber attacks: The number and complexity of cyber attacks, including ransomware and phishing, are steadily increasing.
- Data sensitivity: Many organisations handle sensitive customer data, like credit card details and addresses. Cyber security is a critical priority for these organisations.
- Digital transformation: Everything has become digital. Remote work and cloud computing have increased the number of ways hackers can access company systems, which creates a greater need for cyber security.
- Skills gap: The demand for cyber security professionals far outweighs the supply.
- Economic impact: Cyber attacks have major financial implications such as direct loss, legal fees and reputational damage.
