Google to absorb a key player in cloud security

In March 2025, Google announced(opens in new window) the agreement to acquire the Israeli-US cloud security platform Wiz for a staggering $32 billion. This merger would be the biggest acquisition in Google’s history and another step toward Google’s entrenched power over digital markets.

Wiz is a fast-growing cybersecurity company which started as a cloud-agnostic challenger to both hyperscalers’ native tools and traditional vendors. As a multi-cloud security layer, Wiz provides visibility across Amazon Web Services, Azure, Google Cloud Platform and other environments. If Google acquires Wiz, this neutral multi-cloud visibility could be absorbed into Google’s ecosystem, enabling it to align Wiz’s products and roadmap with its own cloud strategy.

Google expanding into the cloud market

The acquisition of Wiz is not a new move but part of Google’s broader mergers and acquisitions (M&A) strategy over the years. SOMO’s Big Tech M&A tracker revealed that Google acquired at least 43 companies between 2019 and 2025, with more deals added in 2025.

The acquisition of Wiz follows Google’s other recent significant mergers in cloud security, including the acquisition(opens in new window) of Mandiant for $5.4 billion and the acquisition of Siemplify, reportedly(opens in new window) for $500M in 2022. Considering Google’s power in related markets, including cloud services, the proposed merger raises concerns about potential anti-competitive effects.

If approved, the acquisition of Wiz could further strengthen Google’s already significant power in digital markets(opens in new window) , potentially resulting in a “walled garden” in which users and consumers are locked into a single ecosystem. This could undermine competition in the internal market by reducing consumer choice and raising barriers to entry, particularly for smaller cloud providers. The strategic importance of the cloud sector, combined with the sensitivity of security-related issues, further heightens the risk of increased European dependence on a limited number of hyperscalers such as Google, Microsoft and Amazon.

European Commission must act before it’s too late

Given the complexity of the transaction and the potential risks, the Google/Wiz merger warrants a thorough assessment by the Commission. Beyond competition concerns, the deal also raises a geopolitical issue: it would further entrench a US-based tech giant as central to critical digital infrastructure in Europe.

SOMO, with partner organisations Article19, Balanced Economy Project, Rebalance Now and Open Markets Institute, filed a submission to the European Commission(opens in new window) , urging it to open an investigation. The Commission has until 10 February to review Google’s acquisition proposal and decide whether to clear the deal or open an in-depth merger investigation.

Therefore, we urge the Commission to open a detailed investigation into Google’s largest acquisition in its history to keep Europe’s cloud and cloud security markets competitive and resilient.
