Upwind, the runtime-first cloud security leader, announced that it has raised $250 million in Series B funding, bringing its total funding to $430 million. The round was led by Bessemer Venture Partners, with participation from Salesforce Ventures and Picture Capital. Existing investors include Greylock, Cyberstarts, Leaders Fund, Craft Ventures, TCV, Alta Park, Cerca Partners, Swish Ventures and Penny Jar Capital. The Series B marks the beginning of what Upwind calls “The Next Wave,” its next phase of growth focused on scaling runtime-first cloud security to enable a new era of AI and real-time cloud applications for enterprises globally.
“Cloud infrastructure has changed faster than the security models designed to protect it,” said Amiram Shachar, CEO & Co-founder at Upwind. “The next era of cloud security requires a fundamentally different approach, centered in realtime 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.”
Cloud security remains a massive and still maturing market, and within that, Cloud-Native Application Protection Platform (CNAPP) has emerged as a core category for securing modern cloud environments. According to Frost & Sullivan, the global CNAPP market is projected to reach $18.79 billion by 2029, growing at about 28% per year. Gartner also predicts that by 2029, 40% of enterprises that successfully implement zero trust in cloud service provider environments will rely on CNAPP solutions for advanced visibility and control. As cloud and AI adoption accelerate, cloud-native architectures have outgrown approaches based on posture snapshots and static signals, which drive heavy alert volume without clearly showing what is truly exploitable.

Upwind was founded on a different belief: cloud security must be built on runtime evidence, the only way to secure the new world of cloud applications, helping teams reduce noise, prioritize real risk and move faster without slowing the business. Today, Upwind is one of the fastest-growing independent cloud security companies in the market, emerging as a challenger to legacy approaches amid rapid industry consolidation.
“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.
“Upwind is incredibly impressive. We are honored to invest in and partner with them, as their pace of innovation is relentless. If you have seen them before, I strongly suggest you meet with them again. If you haven’t seen them yet, you owe it to your organization and architecture to see what they’ve built,” said Rakesh Loonkar, Managing Partner at Picture Capital.
Upwind’s momentum reflects more than rapid growth. It signals a broader shift in how enterprises are approaching cloud security as environments become more complex and teams demand stronger context for faster decisions. Since its $100 million funding round just a year ago, Upwind has rapidly expanded its platform and accelerated growth, achieving 900% year-over-year revenue growth and 200% logo growth.
During this period, Upwind scaled its global footprint significantly, expanding its workforce from 150 to more than 300 employees, and deepened its presence across core markets including the U.S., U.K. and Israel – with momentum building in Australia, India, Singapore and Japan. Today, 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 prioritize real risk using runtime context rather than static signals.
“Cloud security has been missing real context for too long,” said Jerich Beason, CISO at Waste Management. “Upwind changes that by showing us what is actually happening at runtime and why it matters. The agent built on top of the platform lets us interrogate our own data in real time, which saves us time and money while making our cloud security operations more efficient and effective. They are building the future of cloud security, and we are glad we got on board early.”
