The 15 Largest Cybersecurity Companies In The World, And What They Do

Some decades ago, no one knew that there would ever exist something like cybersecurity. However, innovations have made it possible to have things like technology, and as a result, new threats have emerged in the industry.

Cybersecurity is a fast-growing industry that has grown from almost nothing to a $200 billion market in just the last few years. According to the latest prediction from research firm Fortune Business Insights, the global cybersecurity market is expected to reach USD 376.32 billion by 2029.

With cybercrime continuing to grow and new threats emerging every day, there is no sign that the need for cybersecurity companies will slow down anytime soon. 

In this article, we take a look at some of the largest cybersecurity companies in the world today. These are companies whose businesses are almost entirely dedicated to cybersecurity — not just security software as part of their broader business model.

Each of these businesses falls into one of three main categories: software solutions, services providers, and hybrid security businesses that provide both solutions and services.

What Is CyberSecurity?

Cybersecurity is the practise of protecting computer systems and networks from unauthorized access and malicious attacks. It aims to prevent unauthorized people from accessing or manipulating the sensitive information that is held on the computer system. It also involves implementing measures to detect and respond to any potential threat.
