Cloud security start-up Upwind has raised $400 million in a Series C round at a $3.8 billion valuation. According to TechCrunch, the company had earlier turned down an acquisition offer from Datadog at roughly the same valuation, choosing to stay independent. The new money will go towards protecting cloud infrastructure and AI systems. The funding was announced on 28 October.

What it means: The funding shows that investors see security for AI workloads as a separate and growing market, beyond classic cloud protection. Companies now run models, AI agents and data pipelines with access to credentials, databases and internal systems, and traditional tools were not designed to watch such flows. Upwind's rejection of Datadog also shows how intense consolidation in the sector has become: large monitoring and security platforms buy smaller ones to offer everything in one package. For Greek businesses using AWS, Azure or Google Cloud, the trend means more choice but also more complex decisions. Before buying a new tool, it is worth checking what the cloud provider's native security services already offer, as they often cover the basic needs. For smaller teams, correct permissions, encryption and event logging are often worth more than an expensive specialised tool. Consolidation in the sector may also change the prices and terms of services already in use.
