The acquisition of Nyx Security expands Upwind’s runtime protection to include application-level insight, helping customers detect and remediate more threats in real time

Upwind, a next-generation cloud security provider, announced today its first-ever acquisition, Nyx Security, an embedded cybersecurity startup. The acquisition accelerates Upwind’s expansion into application runtime security, establishing the company as the leader in runtime security by combining cutting-edge application analysis with its existing strength in protecting cloud infrastructure.

Legacy tools weren’t built for today’s cloud-native world – let alone for real-time AI-driven threats. Security teams are falling behind, buried in noise and blind to what’s really happening inside their applications. The Nyx Security acquisition allows Upwind users to understand application code-level anomalies in runtime, giving them the added ability to identify and mitigate threats to the applications running on the cloud. The more comprehensive offering provides organizations with an additional layer of security across their cloud workloads and applications, without adding tools to their technology stacks. While others focus narrowly on posture or siloed detection, Upwind is leading the next wave – delivering real-time visibility and protection across both infrastructure and application layers.

“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.”

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.

“Upwind’s cloud security platform brings powerful runtime visibility and control across infrastructure,” said Alon Saban, co-founder, Nyx Security. “By combining this with our Application Detection and Response (ADR) capabilities at the application layer, we are delivering what the market urgently needs: true runtime security, capable of detecting and mitigating attacks in real time, exactly where they happen.”

Nyx has developed innovative technology in the field of runtime security for the application layer, which allows it to identify when each function in the application is activated. This capability allows the solution not only to locate vulnerable code that is loaded into memory, but also to identify behavioral anomalies that change the way the code operates in real time. With the acquisition, the Nyx team will be brought on board to strengthen Upwind’s development capabilities in eBPF, runtime detection and application-layer observability.

The acquisition – a first for Upwind – marks a key strategic milestone for the company, underscoring its commitment to building the industry’s most comprehensive cloud-native runtime security platform. The move supports Upwind’s ongoing vision to redefine real-time cloud and application security. To learn more about runtime intelligence and the Upwind Platform, visit upwind.io.
