Delray Beach, Fla. – October 02, 2026 -- The global Extended Detection and Response (XDR) market is projected to grow from USD 10.98 billion in 2026 to USD 38.09 billion by 2031, a compound annual growth rate of 28.2%, according to MarketsandMarkets. The market stood at USD 7.92 billion in 2025, reflecting accelerating enterprise adoption of unified threat detection platforms.
Identity-based attacks drive integration of detection signals
Growing reliance on cloud applications, hybrid identities, service accounts, and machine-to-machine authentication is pushing organizations toward XDR to correlate identity behavior with endpoint and cloud activity. Microsoft notes that non-human identities can carry high privileges, making lateral-movement detection a priority for security teams managing increasingly distributed infrastructure.
Native, single-vendor XDR platforms hold largest market share
Native XDR is expected to maintain the largest segment share through the forecast period as enterprises consolidate telemetry from endpoints, networks, cloud, identities, email, and applications within a single vendor ecosystem. Microsoft Defender XDR and Palo Alto Networks' Cortex XDR are cited as examples enabling centralized investigation and automated response, reducing security-tool sprawl.
Services segment and open XDR post fastest growth rates
By offering, services are forecast to grow at a 29.5% CAGR, with managed services holding the largest market size. Among platform types, open/multivendor XDR is projected to expand fastest at 30.3% CAGR, as organizations seek flexibility across mixed security-tool environments.
SMEs register highest CAGR amid resource constraints
Small and medium-sized enterprises are expected to post the highest CAGR in the market, driven by expanding cyber threats and limited internal security staffing. Increasing XDR availability through MSP and MSSP channels is making enterprise-grade detection accessible to resource-constrained SMEs, with Microsoft highlighting simplified deployment and unified visibility as adoption drivers for this segment.
North America to capture 36.9% share on vendor density
North America is estimated to account for 36.9% of the XDR market in 2026, supported by a mature cybersecurity ecosystem and the presence of major providers including CrowdStrike, Palo Alto Networks, Microsoft, Cisco, and SentinelOne. Canada's 2025 National Cyber Security Strategy, which established the Canadian Cyber Defence Collective, is reinforcing demand for threat monitoring and intelligence-sharing capabilities across businesses and critical infrastructure.
Funding and M&A activity target AI-native telemetry management
In April 2025, Gradient Cyber secured Series A investment from First Analysis to scale its 24/7 managed XDR services combining AI-driven telemetry analysis with human-led investigation. In April 2024, SilverSky raised an investment round to expand its managed XDR platform and global go-to-market strategy. SentinelOne's planned acquisition of Observo AI reflects a broader shift toward AI-native telemetry management, while recent transactions involving Palo Alto Networks and Trend Micro point to platform consolidation extending XDR capabilities toward agentic endpoint security and SOC orchestration.
Twenty-six vendors compete across endpoint, cloud, and identity domains
CrowdStrike (Falcon), Palo Alto Networks (Cortex XDR), SentinelOne (Singularity XDR), Cisco (Cisco XDR), and Microsoft (Defender XDR) lead a field that also includes Check Point Software, Fortinet, Trellix, Trend Micro, Sophos, IBM, Bitdefender, Qualys, Broadcom, Rapid7, Exabeam, and eSentire, among others.
