Largest Security Deal of All-Time Aims to Boost AI-Driven Multi-Cloud Solutions

Google plans to make the largest cybersecurity acquisition in history, purchasing Wiz for $32 billion to enhance multi-cloud security and further integrate AI into cybersecurity.

The Silicon Valley-based search and public cloud giant said buying New York-based Wiz underscores its commitment to multi-cloud solutions, and it plans to ensure Wiz is compatible with Amazon Web Services, Microsoft Azure and Oracle Cloud. The deal announcement comes just eight months after Wiz turned down a $23 billion offer from Google, citing a desire to become an independent, public company.
“Organizations are looking for cybersecurity solutions that improve cloud security and span multiple clouds,” Google CEO Sundar Pichai told investors Tuesday. “Wiz is an innovative, leading cloud security platform trusted by more than 50% of Fortune 100 companies who already use their products and services. It continues to deliver new products with strong adoption, defining entirely new categories.”
This will be the largest-ever purchase of a pure-play cybersecurity firm, dwarfing Advent and Permira’s $14 billion buy of consumer cyber vendor McAfee in March 2022. It’s also the biggest deal in Google’s quarter-century history, besting the company’s $12.5 billion purchase of Motorola Mobility in 2012. Alphabet’s stock is down $3.37 – or 2.03% – to $163.20 per share, the lowest it has traded since October 2024.
Google’s security platform includes SIEM capabilities developed in-house with Chronicle, which have been supplemented by the $500 million purchase of SOAR provider Siemplify in early 2022 and the $5.4 billion acquisition of incident response and threat intelligence vendor Mandiant in late 2022. Wiz most recently received a $12 billion valuation after closing a $1 billion Series E funding round in May 2024.
Wiz has spent $800 million on a pair of acquisitions over the past year, purchasing cloud detection and response startup Gem for $350 million in April 2024 to address security operations and incident response use cases. Then in November 2024, Wiz bought application security posture management startup Dazz for $450 million to address vulnerabilities from code to cloud. Google’s buy of Wiz is expected to close in 2026 (see: Why Google Is Eyeing a $23B Buy of Cloud Security Phenom Wiz).
What Google Cloud and Wiz Can Achieve Together
Joining Google Cloud’s AI-driven threat intelligence with Wiz’s real-time attack detection will give firms more visibility into their cloud environments. Wiz’s automated security tools will help companies cut operational costs while enhancing their overall security posture. The deal will provide businesses with additional flexibility in how they secure their infrastructure by supporting multiple cloud providers.
“We believe Wiz and Google Cloud can accelerate the ability of organizations to improve their security, lower the cost to do so, and ultimately spur the adoption of multi-cloud and cloud computing for customers, partners and the industry as a whole,” Pichai told investors Tuesday. “I’m super excited about this announcement and what it means for the future.”
By integrating Wiz into Google Cloud, the company aims to provide a cybersecurity platform that can prevent, detect and respond to threats at every stage of the software development life cycle. Google also plans to further use AI to detect, investigate and respond to security incidents with minimal human intervention, which will reduce the workload on security teams and help businesses act faster.
“Our commitment to multi-cloud means that new IT projects an organization does with Google Cloud can work with their existing IT investments and allows them to choose different vendors for projects in the future,” Google Cloud CEO Thomas Kurian told investors. “Customers don’t want to be locked into one vendor. They want to use a number of clouds, and we’re helping them with this every day.”
With the acquisition of Wiz, Kurian said Google’s AI will be able to scan security logs, detect anomalies and prioritize critical threats before attackers exploit them. AI will help automate security response, reducing the manual workload on security teams and enabling faster mitigation of breaches, while helping businesses analyze cyberattack trends to predict future threats, which will help with preparation efforts.
“To help scale cybersecurity professionals and teams, we will continue to integrate AI-powered cybersecurity tools to assist in summarizing and prioritizing threats, analyzing cloud security configurations for risks and vulnerabilities, AI-powered analysis, and automated AI-powered remediation workflow,” Kurian told investors.
What Makes Wiz’s Approach to Cloud Security Unique
By buying Wiz, Kurian said Google is reinforcing its commitment to multi-cloud solutions, ensuring that customers can secure workloads across multiple cloud platforms without restrictions. This helps clients choose the best cloud providers for specific workloads while maintaining a unified security posture. Kurian said Google Cloud will also expand its security marketplace, boosting access to security tools.
“After close, Wiz will maintain full support as a multi-cloud solution, continuing to partner with all major clouds, including AWS, Azure, Oracle and others,” Kurian told investors Tuesday. “This continues our strategy with Google security operations, which today provides the ability to analyze information and logs from all these major clouds and on-premise environments.”
Wiz’s platform continuously scans an organization’s code, infrastructure and applications, mapping out potential attack paths and prioritizing risks based on real-world impact, CEO Assaf Rappaport said. The platform not only identifies threats but also provides actionable insights throughout the development life cycle that help developers and security teams work together to fix vulnerabilities proactively.
“Developers now have the freedom to choose their own tech stack and move fast, driving innovation in an unprecedented pace,” Rappaport told investors on Tuesday. “But this agility also broke traditional security models, leaving organizations vulnerable. We took a fresh approach, creating a new operating model for modern, multi-cloud development.”
Google’s zero trust security model is used internally and integrated into its cloud security offerings, Pichai said, ensuring that every access request is verified and limited based on context. While AI can enhance threat detection and automate responses, Pichai said it also introduces new risks such as adversarial AI techniques that can be used by hackers.
“We protect users and customers using the same technologies and approaches we use to fortify our own operations, and we build products with the latest security built in so that they are always protected,” Pichai said.
