Upwind Security is Building the Next Wave of Cloud Security

Upwind, building the world’s best cloud security platform, led by Amiram Shachar, Tal Zur, Tomer Hadassi, Rinki Sethi, and others, has raised $250M in a Series B funding round, from Bessemer Venture Partners, Picture Capital, Greylock Partners, Cyberstarts, Craft, Leaders Fund, Swish Ventures, Cerca Partners, Alta Park Capital, TCV, and Penny Jar Capital, bringing the total investment in Upwind to over $430M.

Upwind has raised $250M in Series B, bringing total funding to $430M and cementing its status as a unicorn in cloud security just two years after exiting stealth. The company positions itself as one of the most well-capitalized players in the category, focused on solving cloud security challenges for the next decade, while staying focused on execution and long-term growth.

Upwind’s journey began with a spark of friendship and fast decisions. Early connections with investors like Cyberstarts, Greylock, and Craft provided rapid feedback and support, shaping the company from seed to Series B. This humble, iterative approach continues today with Bessemer Venture Partners and Picture Capital, whose backing allows Upwind to focus on building the right solutions for long-term impact.

Upwind isn’t about incremental improvements. Cloud security was outdated, built for simpler times, while complexity, data growth, and AI-driven risk surged. From day one, Upwind was designed for continuous change, real-world complexity, and the future of cloud infrastructure. This vision guides every decision the company makes.

This Series B validates that cloud, data, and AI have changed the security landscape, and solving it requires a new approach. The funding lets Upwind scale faster, deepen platform capabilities, support more customers, and keep building with discipline. The mission: help security teams operate confidently in a world that never slows down.
