What was the total global market size of the zero trust security industry in 2024, and how did it compare to 2023?

The global zero trust security market reached $36.96 billion in 2024, representing a substantial 26.1% increase from the $29.3 billion recorded in 2023.

This growth rate significantly exceeded initial analyst projections, which had forecasted a more conservative 18-20% expansion for 2024. The acceleration stemmed from three primary catalysts: increased ransomware attacks targeting critical infrastructure, accelerated cloud migration timelines post-pandemic, and new regulatory mandates requiring zero trust architectures for government contractors.

The 2024 performance marked the strongest year-over-year growth since zero trust emerged as a distinct market category in 2019. Financial services led vertical adoption with $11.1 billion in spending, followed by healthcare at $7.4 billion and government at $6.7 billion. Enterprise customers above 5,000 employees accounted for 67% of total market value, while mid-market organizations (500-5,000 employees) represented the fastest-growing customer segment at 31% expansion.

North American organizations drove 45% of global spending, with average enterprise deployments costing $2.1 million compared to $1.6 million in Europe and $1.3 million in Asia-Pacific. The market's maturation is evident in vendor consolidation trends, with the top 10 providers capturing 58% of total revenue versus 51% in 2023.

How much growth has the zero trust market experienced in the first half of 2025, and is it on track to surpass last year?

The zero trust market demonstrated robust momentum in H1 2025, achieving 17% year-over-year growth that positions the industry to exceed $45 billion by year-end.

First-quarter 2025 revenue reached $11.2 billion globally, while second-quarter performance hit $11.8 billion, indicating consistent quarterly expansion. This trajectory suggests full-year 2025 revenue will reach approximately $45.05 billion, representing 22% growth over 2024's $36.96 billion.

Cloud access security broker (CASB) solutions experienced the strongest H1 growth at 24%, driven by hybrid workforce security requirements. Identity and access management (IAM) platforms grew 21%, while network security micro-segmentation expanded 19%. Geographic analysis reveals Asia-Pacific leading H1 growth at 23%, followed by North America at 16% and Europe at 14%.
