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.

What Is CyberSecurity?

Cybersecurity is the practice of protecting computer systems and networks from unauthorized access and malicious attacks.
