Modern enterprise security teams are locked in an escalating crisis where attackers leverage automation and AI to compress attack lifecycles to an unprecedented scale. According to the Unit 42 2026 Global Incident Response Report, the fastest adversaries now reach data exfiltration in just 72 minutes, moving four times faster than the previous year. Security teams no longer have the luxury of hours to manually investigate, triage, and contain incoming threats.
7 Years of Unrivaled Leadership
To evaluate how enterprise controls hold up against high-speed tradecraft, independent testing body AV-Comparatives put Palo Alto Networks Cortex XDR, entering the test with its base XDR Prevent license through its 2026 Endpoint Prevention and Response (EPR) evaluation.
We’re excited to share that Cortex XDR has earned the AV-Comparatives Certified Leader status for the 7th consecutive year, reinforcing our position as an industry leader in endpoint security. Sustaining a leadership position in independent testing year after year proves that enterprise-level defense isn’t a one-off win: it’s continuous operational excellence. Every test cycle shakes up the landscape, but holding the line year in and year out is what separates baseline tools from battle-tested security.
2026 EPR Performance Highlights
- 100% Attack-Chain Containment: Out of 50 advanced scenarios, zero threats reached Phase 3 (asset breach/data exfiltration).
- Phase 1 Initial Defense: Blocked 94% of threats (47/50) immediately upon initial execution.
- Phase 2 Propagation Interception: Stopped 100% (50/50) of the remaining threats during internal spread, completely eliminating lateral movement.
- Zero Operational Friction: Achieved low operational accuracy costs and zero workflow delay penalties during sandbox analysis.
Uncompromising Security, Proven Operational Value
The AV-Comparatives 2026 EPR Product Validation Report offers clear, independent proof: Palo Alto Networks Cortex XDR seamlessly blends elite breach prevention with high-efficiency cost control. Seven consecutive years of AV-Comparatives certification demonstrate that Cortex XDR’s defenses are not just effective in a single snapshot, but consistently resilient against an accelerating threat landscape. For SecOps teams, this means less alert fatigue, zero operational delays, and complete confidence that threats are stopped before reaching critical assets. Selecting Cortex XDR is more than a security upgrade; it is a long-term investment in streamlined, automated operational excellence.
