Palo Alto Networks has completed its acquisition of Chronosphere, a cloud-native observability specialist. The transaction, first agreed in late 2025, closes a landmark chapter in the cybersecurity vendor’s effort to unify deep data visibility with autonomous threat detection and remediation.
Chronosphere recognised as a Leader in the 2025 Gartner® Magic Quadrant™ for Observability Platforms. Its platform excels at ingesting and analysing vast telemetry streams, metrics, traces and logs, while helping organisations manage costs and complexity in cloud-native and AI-driven workloads.
Under the deal, Chronosphere becomes a wholly owned part of Palo Alto Networks, with co-founder Martin Mao stepping into the role of Senior Vice President and General Manager of Observability within the broader Palo Alto organisation.
Central to Palo Alto’s vision is the planned integration of Chronosphere’s observability capabilities with its Cortex AgentiX platform, an AI-powered security automation engine.
Nikesh Arora, Chairman and CEO, Palo Alto Networks, framed the acquisition as a response to evolving enterprise demand: “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.”
Martin Mao added that the partnership allows Chronosphere’s technology to reach a broader global customer base and sets a “new standard, where observability, security, and AI come together to give organisations control over their most valuable asset: data.”
The acquisition, initially announced in November 2025 as a $3.35 billion transaction to be financed with a mix of cash and replacement equity awards, marks one of Palo Alto’s most significant deals outside of its pending CyberArk acquisition.
Chronosphere reported annual recurring revenue (ARR) of over $160 million with triple-digit year-over-year growth as of September 2025, illustrating strong market traction ahead of the close.
