Cybersecurity Market Report Q4 2025

Keypoints

• Annual cybersecurity market reports typically begin with an executive summary or market outlook, followed by sections on total addressable market, current and forecasted spending, major threat drivers, vendor and industry leader analysis, government or regional spending, and broader market definitions or methodology.
• They usually provide forward-looking projections, historical comparisons, and commentary from industry experts to explain growth, budget pressure, and shifts in buyer behavior.
• The “Total Addressable Market” section commonly estimates overall revenue opportunity across global B2B and B2C markets and may expand the scope to include adjacent areas such as cyberinsurance, physical security, surveillance, quantum security, military cyber defense, and space cyber defense.
• In this report, global cybersecurity spending is forecast at $454 billion in 2025, up from $260 billion in 2021, with Cybersecurity Ventures predicting $522 billion in 2026 and $1 trillion annually by 2031.
• IDC forecasts global security spending at $377 billion in 2028, showing continued expansion across security software, hardware, and services, including managed and professional services.
• AI is described as a major force expanding the market, with McKinsey cited as estimating a $2 trillion total addressable market for cybersecurity providers due to AI-driven opportunities.
• Non-CISO cybersecurity spending is gaining importance, already representing nearly 15 percent of corporate cybersecurity spending and expected to grow at a 24 percent CAGR over the next three years.
• The report emphasizes that security budgets are increasingly tied to business risk, critical processes, and strategic objectives rather than being framed only as IT line items.
• A recurring theme is that cyberthreat complexity and frequency are rising, accelerated by generative AI and AI broadly, pushing organizations toward more advanced defensive measures.
• IDC data shows the U.S. and Western Europe will account for more than 70 percent of global security spending in 2025, while Latin America, Central and Eastern Europe, and the Middle East and Africa are expected to see the fastest growth.
• The report notes that traditional “IT security” definitions are too narrow and that true cybersecurity includes non-computer devices and non-IT environments such as IoT, industrial systems, vehicles, medical devices, aviation, and maritime platforms.
• Cybercrime is presented as a major macroeconomic threat, with cited analysis projecting global cybercrime costs of $10.5 trillion by 2025, making it one of the world’s largest economic forces.
• Big tech remains a major buyer and seller in the market, with Microsoft generating around $37 billion in cybersecurity revenue in fiscal 2025 and Google pursuing Wiz in a $32 billion acquisition attempt.
• Security services remain a large and growing segment, with Gartner cited as placing worldwide security services revenue above $77 billion in 2024 and Deloitte holding the largest market share at 16.6 percent.
• The report lists leading pure-play cybersecurity vendors by revenue, led by Palo Alto Networks at $9.22 billion, followed by Fortinet, CrowdStrike, Gen Digital, F5, Zscaler, Okta, and Check Point Software.
• Government defense spending is substantial, with the U.S. spending more than $25 billion annually on cybersecurity for federal systems against hackers, ransomware groups, and state-sponsored actors.
• Deltek’s estimate of the federal cybersecurity market at $18.8 billion in 2026, rising to $20.7 billion in 2028, underscores continued public-sector demand.
• The report highlights cyber-physical resilience as a growing concern, using train and locomotive IoT deployments as an example of how connectivity creates both efficiency gains and new attack surfaces.
• Overall, the report’s central takeaway is that cybersecurity is evolving from a narrow IT function into a broad, cross-sector protection market spanning digital infrastructure, physical systems, national defense, and AI-enabled environments.
