Top Cyber Security Companies in California: An Insider’s Guide


The business of cybersecurity is thriving, especially considering how young a sector it is. According to this estimate, the global market for cyber security went from being worth $3.5 billion in 2004 to over $138 billion in 2017, and it is anticipated that it will reach $232 billion by 2022.

These sorts of projections come from an imprecise branch of research. The sector of cybersecurity is inherently unstable and unpredictable, and as a result, it is subject to its fair share of market fluctuations as well as turnover as new companies enter and exit the industry.

In contrast, the concept that the cybersecurity industry is experiencing a “bubble” that will one day burst seems almost laughable when viewed against the backdrop of persistent assaults that target governments, nonprofit organizations, and businesses of all sizes across all sectors.

Find out more about the most significant actors in the cyber security industry, which is crucial to the functioning of the economy on a global scale and is continuing to see explosive growth.
