20 Biggest Cybersecurity Companies In the World

20 Biggest Cybersecurity Companies In the World: "McKinsey shares that companies and organizations spent $150 billion in 2021 on cybersecurity, but it adds that the threat sector is quite dynamic. The firm's survey of 4,000 companies reveals that 80% of the threat groups and 40% of malware in 2021 were completely new. McKinsey adds that the $150 billion is just a hairline fraction of the total addressable market (TAM) in cybersecurity, and even if there was a ten percent penetration, then the market can blossom to $1.5 trillion."
