Upwind Security announced a $400 million funding round, significantly increasing its valuation to $3.8 billion. The round was led by Bessemer Venture Partners, with continued support from Greylock Partners and Craft Ventures.
The company, founded by Amiram Shachar, Tal Zur, and Lavi Ferdman, has raised a total of $830 million since 2022. It currently maintains a global workforce of approximately 600 employees.
Upwind's core product focuses on identifying threats and vulnerabilities within cloud environments. Recently, the company expanded its capabilities to include monitoring for AI-related threats and protecting AI applications and autonomous agents during runtime.
Why it matters
The funding reflects a broader market trend where venture capital is increasingly flowing into security firms as AI-driven threats become more sophisticated and frequent. Upwind’s platform, which monitors cloud environments for malware and vulnerabilities, has expanded to specifically address AI-related risks, including the monitoring of AI applications and autonomous agents. CEO Amiram Shachar noted that the barrier to entry for malicious actors has effectively dropped to zero due to the availability of AI tools, leading to a significant surge in security incidents and zero-day vulnerabilities over the last three months.
The surge in funding highlights the critical need for security infrastructure capable of defending against AI-powered cyberattacks. As AI tools lower the technical barrier for malicious actors to conduct reconnaissance and manipulation, the demand for automated, real-time security monitoring has intensified.
CEO Amiram Shachar reported that the last three months have seen more security activity than the previous four years combined, underscoring the urgency of the threat landscape. This environment is driving significant capital into startups that can provide specialized defense mechanisms for AI-integrated systems.
The company's reported annual recurring revenue of nearly $100 million serves as a for the commercial viability of AI-focused cybersecurity platforms in the current enterprise market.

What to watch next
Upwind plans to utilize the new capital to scale its engineering efforts and expand its sales and marketing operations. The company is currently on track to reach nearly $100 million in annual recurring revenue by the end of the year. Observers should monitor how the company integrates its AI-specific security tools into broader enterprise cloud environments and whether its growth trajectory continues to outpace the rising demand for AI-native security solutions.
The company's ability to scale its engineering and sales teams will be a key indicator of its long-term market position. With the new capital, Upwind is positioned to accelerate its product development cycle.
Market analysts will be watching to see if Upwind can maintain its growth rate as it competes with both legacy security providers and other emerging AI-native security startups.
The effectiveness of Upwind's tools in mitigating zero-day vulnerabilities and protecting autonomous agents will be a critical factor for enterprise adoption in the coming year.
