Top 8 Online Courses to Learn Cyber Security and Information Security in 2025 - Best of Lot

If you want to learn Cyber Security and Information Security and looking for the best Cyber Security online courses, then you have come to the right place. In this post, I have shared the free Cyber Security and Web Security Courses for beginners.  There is no doubt that Cyber Security and Information Security are essential for business in today's environment, where companies face high risk from malware and other kinds of software viruses and online threats. It's also one of the most overlooked areas from programmers, especially from India and South East Asia, where most computer engineers want to go into application development. 

There is a massive demand for Cyber Security experts, and many computer engineers and computer science graduates can make a promising career in this field. If you already like this field and are looking to get a Cyber Security job, you are in the right place.

 In this article, I will share some of the best courses to learn about Cyber Security from websites like Udemy, Pluralsight, Coursera, and others.

Online training courses are probably the most affordable and best way to develop in-demand skills. 20 years ago, it wasn't that easy to learn advanced Security concepts and techniques, but today you have access to many resources created by Cyber Security experts.

You can join these online courses from the comfort of your office or home and learn the Cyber Security concepts at your own schedule; the only thing required is the willingness and commitment to put in a sincere effort.

I feel sad when I see a Computer Engineer, mainly from India, who doesn't have a job after completing his 2 or 4 years degree just because he doesn't have in-demand tech skills, the tech industry, and market needs.

A part of the blame lies in the Education system, but I prefer to do more than complain and encourage people to learn in-demand skills online to further boost their chances and develop their profiles.

There are many online and offline opportunities, particularly in the IT sector and E-commerce, and all you need is to put some effort to grab them, and Cyber Security is one of them. There are not many Cybersecurity experts out there, and that's why good knowledge in this field can be really good from Jobs and Career perspective.
