Delray Beach, Fla. – – October 07, 2026 -- The global AI Cybersecurity Market is set to grow from $31.25 billion in 2026 to $95.25 billion by 2031, a 25.0% compound annual growth rate, according to MarketsandMarkets. The market stood at $22.07 billion in 2025, underscoring an accelerating pace of enterprise adoption as organizations race to counter machine-speed cyberattacks.
AI-powered threats force defenders to automate at scale
Microsoft reported in 2026 that attackers are embedding AI across the entire attack lifecycle, increasing the tempo, precision, and scale of intrusions, from phishing and reconnaissance to vulnerability discovery and malware development. In response, enterprises are deploying AI-driven detection, threat intelligence, and automated response systems capable of matching adversarial speed. The threat detection and anomaly detection application segment is projected to hold the largest market share through 2031, as organizations correlate signals across endpoints, networks, identities, cloud workloads, and applications to catch threats that bypass signature-based tools.
OT/IoT security and automation emerge as fastest-growing segments
By security function, OT/IoT and cyber-physical security is forecast to post the highest CAGR at 34.2% through 2031. By application, security automation and orchestration is expected to expand fastest at a 36.1% CAGR, reflecting enterprise demand for agentic systems that perform alert triage, investigation, and remediation with minimal human intervention.
SMEs to outpace large enterprises in AI security adoption
Small and mid-sized enterprises are projected to register the fastest organizational CAGR, at 29.3%, as cloud-based AI security platforms lower the cost of entry. The World Economic Forum found that 46% of small organizations report insufficient cybersecurity skills, compared with 29% of large enterprises, widening the capability gap that AI-enabled, low-overhead security tools are designed to close.
North America holds 41.7% market share on hyperscaler and vendor concentration
North America accounted for 41.7% of the AI Cybersecurity Market in 2026, the largest regional share, driven by the concentration of major cybersecurity vendors and hyperscale cloud providers in the US. Federal initiatives are expanding access to AI-powered cybersecurity tools for government agencies and critical infrastructure operators, while NIST advances guidance on AI-enabled cyber defense. Canada is also strengthening AI-driven cyber resilience in response to increasingly sophisticated threats.
Funding rounds signal investor confidence in agentic security platforms
Capital inflows into the sector have been substantial. Cyera raised $400 million in Series F funding in January 2026, pushing total funding above $1.7 billion to expand its AI-native data security platform globally. Torq secured $140 million in Series D funding the same month at a $1.2 billion valuation to scale its agentic AI security operations platform. ReliaQuest raised more than $500 million in March 2025 at a $3.4 billion valuation, while Dropzone AI closed a $37 million Series B in July 2025 to accelerate autonomous SOC agent development. Abnormal AI previously raised $250 million in a Series D round.
Consolidation accelerates as Palo Alto Networks, Google, CrowdStrike pursue M&A
Mergers and acquisitions between January 2024 and September 2026 have concentrated on strengthening AI-driven security operations, cloud security, and agentic detection-and-response capabilities. Recent transactions involving Palo Alto Networks, Google, and CrowdStrike reflect a broader push by established vendors to embed autonomous investigation and machine-speed response across their portfolios, intensifying competition with Microsoft, Cisco, and Fortinet.
