Alphabet’s cloud computing unit has secured its largest security deal to date, striking a nearly $10 billion agreement with Palo Alto Networks that deepens a partnership first formed in 2018, the two companies announced Friday. The expanded relationship puts artificial intelligence at the center of how both companies plan to address a sharp rise in AI-related cyber threats among large enterprises.

A source familiar with the agreement told Reuters that Palo Alto Networks will commit to spending that approaches $10 billion over several years on Google Cloud services. Executives at both firms declined to confirm the figure.

“The contract comprises a commitment by Palo Alto to pay a sum “approaching $10 billion” to Google Cloud over several years,” Reuters reported, citing the person with direct knowledge of the matter.

Palo Alto president BJ Jenkins said part of the investment will fund the migration of existing products onto Google’s cloud platform. A large share will go into building new AI-driven security services designed to meet demand that has surged alongside enterprise use of generative AI.

“AI has spawned a tremendous amount of demand for security,” said Matt Renner, Google Cloud’s chief revenue officer.

Security teams now face attacks created with the same generative tools meant to defend against them. Jenkins compared the moment to the early days of cloud computing, when new infrastructure introduced unfamiliar risks. “This is the same as when the cloud began to emerge, and there were new security threats that no one had ever imagined,” he said.

The deal arrives as Google works to sharpen its competitive stance against Amazon Web Services and Microsoft Azure. Renner described the agreement as proof that Google Cloud sits in a strong position as AI reshapes enterprise buying decisions. Security has become a deciding factor for companies shifting sensitive data and workloads into AI-heavy environments.

Google has spent aggressively to expand that position. Its planned $32 billion acquisition of Wiz, now under regulatory review, would add one of the fastest-growing cloud security platforms to its portfolio. Palo Alto has taken a similar path. The company rolled out new AI-based products in October and recently announced plans to buy observability firm Chronosphere for $3.35 billion.

The relationship between the two firms also has a personal history. Palo Alto CEO Nikesh Arora spent years at Google, serving as chief business officer until 2014. That connection helped lay the groundwork for a partnership that has steadily grown in scope over the past seven years.

Cybersecurity now sits at the center of enterprise AI strategy. Businesses want the gains promised by AI systems, yet the risks have multiplied at the same pace. This agreement signals that major cloud providers and security vendors see the next phase of growth in tightly linking AI infrastructure with defense tools, rather than treating security as an add-on. For Google Cloud, the Palo Alto deal stands as its clearest bet so far that AI security will shape the next chapter of cloud competition.
