Palo Alto's CEO calls for new cybersecurity stack as AI buildout nears $5 trillion

According to Palo Alto Networks CEO Nikesh Arora, businesses need to develop an entirely fresh security framework to support the roughly $5 trillion in capital expenditure on AI infrastructure that he anticipates over the coming half-decade.

Arora made the remarks during an appearance on CNBC's Mad Money on Tuesday, following the cybersecurity company's release of fiscal fourth-quarter results that outperformed Wall Street projections.

Arora Details the Calculation Behind $1 Trillion in Cybersecurity Debt

The CEO noted that artificial intelligence is compelling organizations to upgrade approximately $1 trillion in outdated cybersecurity infrastructure that cannot respond to attacks occurring at machine speed.

“There’s approximately $1 trillion of global cybersecurity debt that must be modernized to defend against automated threats because they operate instantaneously,” he stated during the earnings call.

He derived that figure using straightforward math. Security hardware typically has a lifespan of around seven years, with annual spending ranging from $200 billion to $300 billion.

“You’re going to see $5 trillion of capex spend in the next five years with people building AI data centers and having tons and tons of agents running around. You also have to build a net new security stack for that,” he said.

Arora pointed to the debut of Anthropic’s Mythos model earlier this year as a transformative moment for cybersecurity. The model's capacity to detect and exploit software weaknesses prompted companies to treat cybersecurity more seriously.

Financial Results Support the Argument

That heightened sense of urgency is already reflected in Palo Alto’s performance. Quarterly revenue stood at $3.41 billion, climbing 34% year over year, compared with analyst forecasts of $3.35 billion. Adjusted earnings reached $1.02 per share, exceeding expectations by four cents.

Next-generation Security annual recurring revenue hit $9.10 billion, representing a 63% gain. Remaining performance obligations increased 34% to $21.2 billion.

The company issued guidance for fiscal 2027 revenue between $14.10 billion and $14.20 billion, above the $13.79 billion that analysts had projected.
