XSIAM bookings over the trailing 12 months are nearing $1B, signaling growing enterprise adoption.
Palo Alto Networks (PANW - Free Report) has revolutionized the Security Information and Event Management (SIEM) space since the launch of Extended Security Intelligence & Automation Management (XSIAM) in 2022. XSIAM can rightly be called the successor of the SIEM technology.
XSIAM was launched as Palo Alto Networks' advanced SIEM solution, with significant upgrades like AI-driven analytics, automation, enhanced threat detection and response, MITRE ATT&CK Coverage Dashboards and streamlined alert prioritization.
Palo Alto Networks’ Cortex XSIAM is cloud native, whereas the traditional SIEM operates on-prem with siloed data. Traditional SIEM solutions function on signature and correlation rules, while XSIAM uses AI and ML techniques to detect and mitigate risks. Moreover, XSIAM comes with indefinite scalability features as it operates on Palo Alto Networks’ unified cloud platform.
The feature-rich solution gained traction amid rising cyberattacks, resulting in Cortex XSIAM’s annual recurring revenues growing 200% year over year in the fiscal third quarter of 2025. Cortex XSIAM is deployed across more than 270 customers with an Average ARR of $1 million per XSIAM customer. Moreover, the trailing 12-month XSIAM bookings are now close to $1 billion.
For fiscal 2025, Palo Alto Networks expects revenues between $9.17 billion and $9.19 billion. The Zacks Consensus Estimate for fiscal 2025 revenues is pegged at $9.18 billion, indicating year-over-year growth of 14.4%.
How Competitors Fare Against Palo Alto Networks
Other cybersecurity players are also enhancing their traditional SIEM offerings. For instance, CrowdStrike (CRWD - Free Report) offers Falcon Next-Gen SIEM with features like fast search, AI integration, a cloud-native offering with scalability of up to one petabyte of data ingestion per day. CrowdStrike, in its first-quarter 2026 results, reported that its Next-Gen SIEM ARR grew by more than 100% on a year-over-year basis.
International Business Machines (IBM - Free Report) is also enhancing its SIEM capabilities with the introduction of QRadar SIEM Suite, which is cloud native and has added features of XDR, SOAR, and threat detection. The solution seamlessly integrates with IBM Security services, reducing barriers to adoption.
As the traditional SIEM market is getting backdated and under-equipped to handle advanced cyber threats, companies like International Business Machines, CrowdStrike and Palo Alto Networks are upgrading their offerings. The total addressable market for XSIAM or Next-Gen SIEM is large enough to accommodate the growth of multiple players. This is the reason why Cortex XSIAM might become the growth engine for PANW.
