“True runtime security requires understanding the complex interplay between cloud infrastructure and the applications running on it,” said Amiram Shachar, co-founder and CEO, Upwind. “The acquisition of Nyx Security solidifies our position as the leader in runtime security. Nyx brings groundbreaking technology that tracks which functions in an application are actually executed in runtime, allowing for surgically precise detection of exploited vulnerabilities and behavioral anomalies. The team brings deep expertise in application-layer analysis, embedded systems and low-level threat detection. Building on Upwind’s leading capabilities in cloud runtime security, we are now uniquely equipped to provide holistic, future-proof protection for modern cloud-native workloads.”
Upwind seeks to streamline the overwhelming volume of alerts generated by threat detection tools, aiming to reduce them by 90%. This reduction allows security operations teams to concentrate on genuine threats, enabling quicker understanding and response times.
Founded by Amiram Shachar and his founding partners from Spot.io (sold to NetApp for $450 million), Liran Polak, Lavi Ferdman, and Tal Zuri, Upwind Security says that its mission is to empower organizations to run cloud environments and accelerate their businesses by focusing on what is next — helping make cloud-native security simple, effective, and easy to consume.
Nyx Security was founded in 2024 in Tel Aviv by Gili Yankovich and Alon Saban. Yankovich was previously a technology leader at Check Point Software after the acquisition of his company Cymplify Security. He brings deep expertise in embedded software and low-level research. Saban has extensive cybersecurity leadership experience, including serving as an EVP at HUB Security and holding senior roles within elite military cybersecurity units.
“As we advanced our technology to detect and respond to threats at the runtime level – where applications actually execute and where attacks unfold – we understood that scaling this innovation required the right strategic partner,” said Gili Yankovich, co-founder, Nyx Security.
