Palo Alto Networks Acquires Chronosphere to Unite Observability and Security
Delivers real-time visibility, monitoring, and protection for the massive data volumes that power AI-driven digital operations
As enterprises increasingly rely on AI to run digital operations, protect assets, and drive growth, success depends on one critical factor: trusted, high-quality, real-time data. Palo Alto Networks the global cybersecurity leader, today announced it has completed its acquisition of Chronosphere addressing a core challenge of the AI era: the inability to see and secure the massive data volumes running modern businesses.
Chronosphere, a Leader in the 2025 Gartner® Magic Quadrant™ for Observability Platforms,1 was purpose-built to handle this scale. While legacy tools break down in cloud-native environments, Chronosphere gives customers deep visibility across their entire digital estate. With this acquisition, Palo Alto Networks is redefining how organizations run at the speed of AI — by enabling customers to gain deep, real-time visibility into their applications, infrastructure, and AI systems — while maintaining strict control over data cost and value.

The planned integration of Palo Alto Networks Cortex® AgentiX™ with Chronosphere’s cloud-native observability platform will allow customers to apply AI agents that can now find and fix security and IT issues automatically — before they impact the customer or the bottom line. AI security without deep observability is blind; this acquisition delivers the essential context across models, prompts, users, and performance to move from manual guessing to autonomous remediation.
Nikesh Arora, Chairman and CEO, Palo Alto Networks:
“Enterprises today are looking for fewer vendors, deeper partnerships, and platforms they can rely on for mission-critical security and operations. Chronosphere accelerates our vision to be the indispensable platform for securing and operating the cloud and AI. We believe that great security starts with deep visibility into all your data, and Chronosphere provides that foundation for our customers.”
Martin Mao, Co-founder and CEO, Chronosphere is joining Palo Alto Networks as SVP, GM Observability and comments:
“Chronosphere was built to help the world’s most complex digital organizations operate at scale with confidence. Joining Palo Alto Networks allows us to bring AI-era observability to a global audience. Together, we’re delivering a new standard — where observability, security, and AI come together to give organizations control over their most valuable asset: data.”
The Chronosphere Telemetry Pipeline remains available as a standalone solution, enabling organizations to eliminate the ‘data tax’ associated with modern security operations. By acting as an intelligent control layer, the pipeline can filter low-value noise to reduce data volumes by 30% or more and has been shown to require 20x less infrastructure than legacy alternatives. This will be key to Palo Alto Networks Cortex XSIAM® strategy, ensuring customers can scale their security posture—not their spending—as they transition to autonomous, AI-driven operations.
