Can Rising Network Security Demand Boost PANW's Long-Term Growth?
Read MoreHide Full Article
Key Takeaways
Palo Alto Networks' next-generation firewall bookings grew nearly 40% amid AI data center buildouts.
Software firewall ARR rose 25% as customers expanded capacity to inspect cloud and AI workload traffic.
Palo Alto Networks expects data center expansion and higher traffic volumes to drive Network Security growth.
Palo Alto Networks (PANW - Free Report) is seeing stronger growth in its Network Security business as enterprises increase spending on AI and cloud infrastructure. Network Security is the company's largest business, accounting for about 70% of total revenues. In the third quarter of fiscal 2026, management said Network Security had its strongest quarter in several years, with growth across hardware, SASE and software firewalls. This gives the business a large base from which to benefit from higher security spending.
Next-generation firewall bookings grew nearly 40% year over year in the third quarter. PANW said demand was supported by its latest Gen 5 appliances and AI data center buildouts. The company is also seeing demand from AI labs and sovereign infrastructure providers, which are new customer groups for its firewall business. Hardware revenues represent about 10% of total revenues, but the business had its best quarter in a decade and ended the quarter with a record backlog. This suggests that AI infrastructure spending is creating an additional demand opportunity for PANW's firewall business.
Software firewalls are adding another source of growth. Software firewall ARR increased 25% year over year as customers expanded their capacity to inspect traffic between cloud and AI workloads. PANW expects AI adoption to create more machine-to-machine traffic, increasing the need for security inspection. Management said customers are using more of its security products, with an average of more than four subscriptions per device in its installed base. This gives PANW another way to increase revenues as customers expand their security deployments.
The increase in AI-related traffic could support Network Security growth over the next several quarters. PANW expects data center expansion and higher traffic volumes to remain key growth drivers for the next few quarters, and potentially several years. With firewall bookings up nearly 40%, software firewall ARR up 25% and Network Security accounting for most of PANW's revenues, continued AI infrastructure spending could make this business an important driver of overall growth.
How Competitors Fare Against PANW
Competitors like CrowdStrike (CRWD - Free Report) and Zscaler (ZS - Free Report) are also gaining ground through platform expansion and AI innovation.
CrowdStrike is also benefiting from rising AI-related cybersecurity demand. CrowdStrike is seeing strong demand for its AI Detection and Response (AIDR) solution. CRWD's AIDR solution is designed to help companies monitor and secure AI applications, agents and workloads as AI adoption grows across enterprises. Management highlighted AIDR as one of the company's fastest-growing products in the first quarter of fiscal 2027. In the first quarter, AIDR's ending ARR grew more than 250% sequentially. Further, AIDR has already secured a pipeline of more than $50 million for the second quarter of fiscal 2027.
Zscaler is seeing strong adoption of its Zero Trust Everywhere strategy, which is helping the company expand beyond its traditional user security offerings. The strategy combines security for users, cloud workloads and branch locations on a single platform. The company ended the third quarter of fiscal 2026 with more than 700 Zero Trust Everywhere enterprises, up from over 550 in the previous quarter. As more customers adopt multiple products across the platform, Zero Trust Everywhere could help Zscaler increase customer spending, win larger deals and support long-term growth.
