AI is expanding a $2 trillion total addressable market (TAM) for cybersecurity providers, according to a 2024/2025 study by McKinsey, a global management consulting firm and trusted advisor to the world’s leading businesses, governments, and institutions.
“One of the areas that is extremely compelling is the opportunity to build a security layer around agentic AI,” says Richard Seewald, founder and Managing Partner at Evolution Equity Partners. “If you think about the volume of agents that will be put into the market, the opportunity to create cybersecurity companies that defend and protect that layer are significant.”
TAM is the total revenue opportunity available to a product or service if 100 percent market share is achieved. TAM does not represent actual dollars spent, or expected to be spent. The TAM figures from McKinsey are global and primarily focused on B2B, but not B2C or other markets converged with cybersecurity such as physical security and surveillance, automotive security, and others.
Global spending on cybersecurity products and services is expected to reach $454 billion annually (USD) in 2025, up from $260 billion in 2021, according to Cybersecurity Ventures.
