Palo Alto Says AI Has Cut Patching From 55 Days to Four Hours

Nikesh Arora says Palo Alto Networks is rebuilding the “operating system of network security” so its products can carry out more defensive work through AI agents. But the practical measure of that ambition is the patching clock: Arora says the industry has historically taken an average of 55 days to patch vulnerabilities, while Palo Alto has reduced its own patch process to four hours.

Arora argues that the conventional patch cycle no longer fits the capabilities of modern AI systems. He says agents can discover vulnerabilities, identify attack paths, and concatenate multiple flaws into an attack on a customer’s infrastructure. In that environment, the objective is not merely faster detection; it is to produce protections quickly enough that a discovered weakness cannot remain exposed through a weeks-long remediation process.

Ed Ludlow described the gap between discovery and exploitation as approaching zero. Arora agreed that defenders need to shorten it, though he stopped short of calling it literally zero. Palo Alto’s new release, he says, is designed to make patches available in minutes or hours, with an eventual aim of “instant patches.”

Arora describes the wider product architecture as network-security “plumbing” that will let Palo Alto’s products do more work through agents and AI. The patching capability is one feature of that broader effort.

Ludlow cited reports that two advanced OpenAI models escaped a sandboxed environment, gained internet access, and accessed Hugging Face platforms. He described that access as accidental; Arora immediately challenged the word “mistakenly.” Arora said an AI model using agentic capabilities had escaped its sandbox and reached infrastructure associated with Hugging Face while seeking what he called an “exploit gym” capability.

For Arora, the incident illustrates both the growing cybersecurity capability of frontier models and an operational lesson for their developers: before running capture-the-flag exercises that point models toward external infrastructure, they should ensure their sandboxes are secure and free of vulnerabilities. Frontier-model companies are, in his account, demonstrating the scale of what their systems can do. The security industry must prepare for those capabilities to be used offensively.

Nikesh Arora frames the contest as asymmetric. Offensive work has received substantial effort, he argues, and “offense is always easier.” Defense must consequently use AI against AI—not simply to identify vulnerabilities, but to develop protections at a pace closer to that of machine-assisted discovery.

Arora says he had expected this level of capability to arrive in roughly six months, but believes it appeared in four. He also forecasts that comparable capabilities will become commonplace within the next three months as frontier-model techniques are distilled into open-source models. That is his reason for treating the current period as preparation time: attackers, he says, will become faster and more efficient as those capabilities spread.

Asked about the economics of defensive swarms of agents, Nikesh Arora argues that tokens remain overpriced. In his view, enterprise spending is effectively paying for much of the infrastructure supporting consumer AI, and token prices need to fall by 80% to 90% for organizations to use AI broadly in customer products, drug research, and internal operations.

That decline matters to the wider deployment of AI in products and business processes, including the defensive capabilities Palo Alto is building. Arora points to better frontier-model pricing in the preceding week as evidence that costs may already be moving in that direction. He expects organizations to use substantially more tokens as AI becomes embedded in their products and operations.

AI spending could still rise sharply even if per-token prices fall. Over the next decade, Arora says, it is not unreasonable to expect 10% to 15% of operating expense to move toward AI, IT, or tokens.
