Palo Alto beats estimates, eyes AI security boom

Palo Alto's results and guidance point to a broader trend in cybersecurity: the rise of capable AI models is creating a new class of threats. CEO Nikesh Arora cited breaches like the OpenAI-Hugging Face hack as proof that AI agents can increasingly plan attacks autonomously, pushing customers to spend on new defenses.

The company has responded with an aggressive acquisition strategy to deepen its AI security offerings. In just over a year, it announced a $25 billion deal for identity security firm CyberArk and a nearly $3.4 billion deal for Chronosphere, its largest acquisitions to date. It also announced the acquisition of AI startup Console in the same quarter, and Arora said the startup ecosystem serves as a "large lab" for potential buys.

Investor appetite for AI security is broad. Last week, rivals CrowdStrike and Okta also saw their shares surge on strong earnings as customers spend more on cyber tools. Palo Alto's shares have nearly doubled this year, though they fell 5% in the regular session before the earnings release, possibly reflecting high expectations baked into the price.
