New capabilities extend real-time application protection and visibility across runtime environments

Upwind, a next-generation cloud security provider, today announced the full integration of Nyx into its product offering, following the successful completion of its acquisition in April 2025. This marks a major milestone in Upwind’s mission to unify cloud infrastructure and application security. With Nyx’s function-level runtime visibility fully embedded in the Upwind platform, customers gain unprecedented depth in threat detection and vulnerability prioritization from infrastructure to the application layer.

Upwind Completes Integration Of Nyx Technology

Upwind is now the first platform to offer true Cloud Application Detection and Response (CADR), delivering a single runtime-native solution that spans process behavior, network activity, API usage, and application function execution. This establishes Upwind as the only CNAPP with fully integrated application-layer runtime protection.

“We acquired Nyx because we believe that runtime is where the real battle for cloud security is happening,” said Amiram Shachar, CEO and co-founder of Upwind. “And now that it’s fully integrated, we’re delivering a single platform that’s purpose-built to observe, understand, and stop attacks across cloud infrastructure and applications in production in real time.”

Live, real-time protection, from the inside out

Attackers are evolving faster than the tools designed to stop them. Traditional cloud security, focused on scanning infrastructure and posture, often misses what happens when code is running and services are live. That’s where attackers are now operating, and it’s where Upwind is uniquely positioned to respond.

Upwind was built from day one to secure live cloud environments through lightweight, high-fidelity runtime telemetry. With the integration of Nyx’s eBPF-based engine, Upwind’s capabilities extend to observing and correlating function-level application behavior, enabling two key capabilities:

• Function-aware vulnerability prioritization: By identifying whether vulnerable functions in third-party packages are invoked at runtime, Upwind can suppress over 60% of false-positive vulnerability alerts, improving triage and reducing alert fatigue for developers and security teams.

• Application-layer threat detection: Combined with Upwind’s existing baselines for process, network, syscall, and API activity, Nyx’s technology adds a new layer of activity-based anomaly detection and runtime forensics, enabling deeper, real-time insight into application-level threats.

These capabilities provide customers with a more accurate view of real risk, faster incident response, and better alignment between AppSec, DevOps, and cloud security teams.

A strategic move in the CNAPP landscape

With this integration, Upwind becomes the first CNAPP provider to offer integrated runtime protection across cloud infrastructure and applications, carving out a differentiated position in a market that has seen rapid expansion but limited innovation in application-layer defense.

While competitors have made moves into shift-left code scanning and static vulnerability analysis, runtime-focused Application Detection and Response (ADR) remains underserved. Upwind now uniquely delivers both in one platform, enabling runtime-first protection from the infrastructure level to the code path.

According to Shachar, the integration was fast-tracked thanks to a shared architectural foundation. Both platforms were built from the ground up for scale, low latency, and zero impact on production environments. Their shared philosophy of “live, in-line security” ensures customers can deploy quickly and gain immediate protection without compromising performance or agility.

“Security has to keep up with the speed of production,” said Shachar. “You can’t wait hours or days to act. Upwind, now with Nyx, provides real-time signal, context, and action - from the infrastructure to the process level. Mergers and acquisitions in the software industry are never easy. A perfectly executed integration, across both culture and technology, is essential to deliver a seamless user experience and a resilient architecture. That’s exactly what we’ve achieved with Nyx.”

Why runtime is now the foundation of modern cloud security

The shift toward runtime exploitation is accelerating. As threat actors become more adept at bypassing traditional guardrails, organizations need more than posture and policy - they need visibility into what’s happening as applications execute. That means seeing every process, connection, and user interaction in real time, with the ability to act before damage is done.

By anchoring security in runtime, Upwind empowers teams to:

• Detect novel threats that static scanners miss

• Prioritize and respond to incidents with full context

• Prevent exploitation as it happens

With the integration of Nyx complete, Upwind now offers a unified platform that combines deep runtime telemetry across cloud infrastructure and applications. Looking ahead, Upwind is committed to expanding into Data Security and AI Security, through both organic execution and strategic mergers and acquisitions, to protect the next generation of cloud-native workloads.

About Upwind

Upwind is the next-generation cloud security platform built to lead the runtime revolution. With rapid momentum and a bold vision to unify cloud and application-layer protection, Upwind helps organizations run faster, detect threats earlier, and secure their environments with unmatched precision. Upwind was founded by Amiram Shachar and his founding partners from Spot.io (which was sold to NetApp for $450 million) and is backed by top cybersecurity investors Greylock, Cyberstarts, Leaders Fund, Craft Ventures, Cerca Partners, and Sheva, a VC fund founded by former NBA player Omri Casspi. The company has secured $180 million in funding since its founding in 2022. For more information or to schedule a demo and see the future of runtime security firsthand, visit www.upwind.io.
