Pinterest LinkedIn Tumblr

Cloud security is not only a hot commodity, but a necessary one, and businesses are steadily increasing their adoption of services provided by the top cloud security companies.

Research firm Markets and Markets estimates that the overall global cloud-managed services market was worth US$99 billion in 2022, and it’s projected to reach US$164 billion by 2027.

According to the firm’s report on the cloud managed services market, the sectors drivers are “(g)rowing demand for cloud managed services among enterprises and inadequate cloud expertise among IT professionals.’

Unfortunately, these services are also vulnerable to the growing number of costly cybersecurity threats and data breaches. Emergen Research sees these threats as fueling growth in the cloud security market to the tune of US$170.51 billion by 2032.

With the industry poised for substantial growth, here’s a look at the top 10 cloud security companies in 2023, according to Emergen Research. Companies are listed in order of market cap, with data current as of market close on September 28, 2023.

Microsoft is making its cloud systems compatible with open-source systems; it is also providing a host of artificial intelligence (AI) applications through Azure, including advanced data analytics, speech recognition and language translation. When it comes to cloud security, Microsoft has a team of cybersecurity threat intelligence experts who have worked with government officials and policymakers. Microsoft leverages its security expertise and experience to create critical cloud infrastructure protections.
