Palo Alto Flags $1 Trillion Cybersecurity Debt
CEO Nikesh Arora says defenses built for human-speed attacks must be upgraded as AI allows vulnerabilities to be found and exploited far faster.

Artificial intelligence could trigger a new cybersecurity spending cycle as companies replace defenses that were not built to withstand automated attacks, according to Palo Alto Networks CEO Nikesh Arora.
“There’s approximately $1 trillion of global cybersecurity debt that must be modernized to defend against automated threats because they operate instantaneously,” Arora said during the company’s earnings call on Tuesday, 1 September.
The figure is Palo Alto’s estimate of aging cybersecurity infrastructure requiring upgrades, rather than a forecast of immediate spending.
“Nothing that was deployed seven or 10 years ago is prepared or ready to handle AI at machine speed,” Arora told CNBC’s Mad Money. “You have to rethink your cyber architecture.”
Arora said cybersecurity could no longer be separated from companies’ broader AI plans. “You cannot deploy AI successfully if you don’t get cybersecurity right,” he said.
The warning comes as increasingly capable AI models are changing the economics of cyberattacks. Tasks that once required teams of skilled hackers can increasingly be automated, allowing vulnerabilities to be searched for and exploited at greater speed and scale.
He identified Anthropic’s April unveiling of Claude Mythos Preview as a turning point. Anthropic said the model had found thousands of previously unknown vulnerabilities and could autonomously develop exploits for flaws in major operating systems and web browsers.

“I’ve been trying for eight years to tell customers they’re not ready, and Dario Amodei did it in one event, just by launching Mythos,” Arora said, referring to Anthropic’s chief executive.
Palo Alto said it had discussed the threat with about 2,000 companies. Its Frontier AI Critical Defense Program, introduced on 19 August, brings together technology companies and critical-infrastructure groups to turn AI-discovered vulnerability intelligence into network-level virtual patches.
The company said frontier AI models had helped it uncover more than 14,000 previously unknown vulnerabilities in open-source software.
Investor sentiment has also shifted. Cybersecurity shares initially came under pressure on concerns that AI could disrupt established security software. Palo Alto’s stock has since more than doubled from 7 April as investors increasingly view AI-driven attacks as a source of additional demand.
Palo Alto’s fiscal fourth-quarter revenue rose 34% to $3.41 billion, while adjusted earnings of $1.02 a share beat Wall Street estimates. The company nevertheless reported a net loss of $282 million under generally accepted accounting principles.
For fiscal 2027, Palo Alto forecast adjusted earnings of $4.16 to $4.19 a share and revenue of $14.1 billion to $14.2 billion. Arora cautioned that the estimated modernization opportunity would unfold over several years rather than translate immediately into spending.
