Furthering its mission to address the critical data demands of the AI era, Palo Alto Networks® (NASDAQ: PANW), the global cybersecurity leader, today announced it has entered into a definitive agreement to acquire Chronosphere, a next-generation observability platform built to scale for the AI era. This acquisition will strengthen Palo Alto Networks’ ability to help organizations navigate a world where modern applications and AI workloads demand a unified data and security foundation.
The growth of these applications and workloads requires constant uptime and resilience, making real-time, always-on observability mission-critical for success. Chronosphere was built precisely for these current needs: a next-generation architecture designed to scale for the AI era and handle vast cloud data volumes with cost-efficiency and reliability at the forefront. It has already proven its reliability and cost-efficiency in production with some of the category-defining companies leading the AI revolution, including two of the premier LLMs.
Nikesh Arora, Chairman and CEO, Palo Alto Networks:
“The foundational requirement for every modern AI data center is constant uptime and resilience, which demands real-time, always-on observability delivered at the right cost. Chronosphere was built to scale for the data demands of the AI era from day one, which is why it is chosen by leading AI-native and born-in-the-cloud organizations. And once we leverage AgentiX with Chronosphere, we will take observability from simple dashboards to real-time, agentic remediation. We are excited to not just enter this space, but to disrupt it.”
Combining Chronosphere’s purpose-built, optimized architecture that can handle some of the largest and most complex digital environments with Palo Alto Networks’ AgentiX™ will transform the value proposition of observability from passive monitoring, to offering a ground-breaking autonomous remediation platform. The new solution will deploy AI agents on the massive amounts of data monitored by Chronosphere’s platform to not only detect performance issues, but also to autonomously investigate the root cause, and close the loop with agentic remediation. Customers will be able to achieve deeper visibility across both security and observability data at petabyte scale, while simultaneously realizing significant cost efficiencies due to Chronosphere’s optimized data ingestion architecture.
Martin Mao, Co-founder and CEO, Chronosphere:
“We founded Chronosphere to provide scalable resiliency for the world’s largest digital organizations. Palo Alto Networks is the perfect strategic partner for our customers, partners, and employees. It allows us to combine our disruptive observability platform with the world’s best security company, accelerating our momentum in solving the most complex data and resiliency challenges. Together, we look forward to continuing to partner with industry-leading cloud and AI-native customers across the world on their mission-critical observability and security needs.”
Chronosphere is recognized as a Leader in the 2025 Gartner® Magic Quadrant™ for Observability Platforms, and will also bring innovative telemetry pipeline capabilities to Palo Alto Networks’ industry-leading platforms to drive powerful data transformation, optimization, and routing that will enable customers to make massive data ingestion economically viable at scale.
Under the terms of the agreement, Palo Alto Networks will acquire Chronosphere for a total consideration of $3.35 billion, to be paid in cash and replacement equity awards, subject to adjustments. Chronosphere reports generating annual recurring revenue (“ARR”) of over $160 million as of the end of September 2025, growing ARR triple-digits year-over-year. The acquisition is subject to customary closing conditions, including regulatory approvals, and is expected to close in Palo Alto Networks’ second half of fiscal 2026.
