As cloud infrastructure becomes more dynamic and AI-driven, traditional security tools struggle to keep up. Many still use static scans and snapshots, which generate too many alerts without clearly showing what is truly vulnerable.
Upwind is taking a different approach by focusing on real-time activity in cloud environments. Their platform helps security teams identify real risks, cut through unnecessary information, and respond quickly without hindering engineers.
“Cloud infrastructure has changed faster than the security models designed to protect it. The next era of cloud security requires a fundamentally different approach, centred on real-time signals. That’s actually the only way to protect the cloud in the new era of AI. We built Upwind for where the cloud is going, not where it has been. This funding round is a small milestone in our journey, but it marks a big day, and it reflects a growing recognition and validates what customers and the market see,” said Amiram Shachar, CEO & Co-founder at Upwind.
Raised $250M in Series B round
The US-based cloud security startup has raised $250 million in a Series B round, taking its total funding to $430 million. The round was led by Bessemer Venture Partners, with participation from Salesforce Ventures and Picture Capital.
With the new capital, Upwind plans to scale its platform globally and invest more heavily across data, AI, and code security. The company also plans to push its runtime approach closer to developers, aiming to catch risky configurations before they reach production.
Since its $100 million funding round just a year ago, Upwind has expanded rapidly, doubling its headcount to 300+ employees and strengthening its presence in the US, UK, and Israel. It is also seeing growing demand in markets such as India, Singapore, Japan, and Australia.
Upwind has rapidly expanded its platform and accelerated growth, achieving 900% year-over-year revenue growth and 200% logo growth.
Unified vision for cloud and application-layer protection
Founded by Amiram Shachar and the founding team behind Spot.io (acquired by NetApp for $450 million), Upwind brings together a unified vision for cloud and application-layer protection, empowering organisations to run faster, detect threats earlier and secure their environments with unmatched precision.
Upwind says it now protects millions of cloud workloads for global enterprises, including Waste Management, Siemens, Roku, Wix, Nubank, and Peloton. Customers report a 98% reduction in security alerts and significantly fewer irrelevant vulnerabilities, allowing teams to focus on real threats.
“Upwind shows us what is actually happening at runtime and why it matters,” said Jerich Beason, CISO at Waste Management. “That context saves time, reduces cost, and makes our security operations far more effective.”
At present, Upwind secures millions of workloads for global enterprises, including Waste Management, Siemens, Carvana, Roku, ClickUp, Wix, Nubank, Agoda, Peloton, Fiverr and BILL, helping security teams cut through noise and focus on what matters most.
Customers report a 98% reduction in security alerts and 60% fewer irrelevant CVEs, enabling teams to prioritise real risk using runtime context rather than static signals.
Over the past year, the company added 100+ new partners across ISVs, MSPs and resellers, launched a strategic partnership with NVIDIA and deepened collaborations with hyperscalers, including Microsoft Azure and AWS.
Together, these efforts reinforce Upwind’s unified runtime-first approach, positioning the company to continue shaping the future of cloud security as enterprise demand accelerates.
“Cloud security is already one of the largest and fastest growing segments in cybersecurity, and Upwind stood out to us as the right team with the right product in the right time, building for where the market is going. Their modern, runtime-first approach, focus on signal over noise, and battle-tested founding team have translated into a company and product that are trusted and loved by security, engineering and platform (DevOps) teams, and used as a true platform. We’re very proud to partner with Upwind as they build the runtime-first cloud security platform for the next generation of enterprises,” said Elliott Robinson, Partner at Bessemer Venture Partners.
