Cylake Raises $45M to Deliver AI-Powered Security Inside Enterprise Infrastructure

In a cybersecurity environment, organizations generate massive amounts of security telemetry across networks, endpoints, cloud systems, and security tools. While many companies have embraced cloud-delivered security platforms to analyze this data, a growing group of organizations simply cannot move sensitive information outside their own infrastructure.

This is the problem Cylake is aiming to solve. Emerging from stealth with an impressive $45 million seed round led by Greylock Partners, the company is introducing a new approach to AI-driven security analytics designed specifically for organizations that require strict control over their data.

Cloud-native security platforms have become the industry standard over the past decade. They allow organizations to centralize telemetry, apply large-scale analytics, and leverage advanced AI capabilities.

However, sectors such as government, defense, critical infrastructure, and highly regulated industries often face strict data sovereignty and compliance requirements. Exporting sensitive logs, network data, or investigation details to the public cloud can create regulatory and operational risks. Cylake is building a platform tailored for these environments.

Instead of sending security telemetry to the cloud, Cylake enables organizations to run AI-powered security analytics entirely within their own infrastructure. This architecture allows enterprises to leverage advanced detection and investigation capabilities while keeping sensitive data under their direct control.

Vision Behind Cylake

Modern security teams struggle with fragmented visibility. Data from network monitoring tools, endpoint protection platforms, identity systems, and cloud environments often exists in separate silos. This fragmentation makes it harder to detect threats and investigate incidents effectively.

Cylake’s platform is designed to unify these data sources through a single analytics layer. Key capabilities include:

• AI-driven security analytics for faster detection and investigation
• Correlation of network, endpoint, cloud, and security tool data
• A unified data layer for security operations and threat analysis
• Deployment fully inside the customer’s environment

By bringing these elements together, Cylake aims to give security teams a comprehensive view of their environment without compromising data privacy or regulatory compliance.

A Founding Team With Deep Cybersecurity Roots

Cylake’s founding team brings significant experience from some of the most influential companies in cybersecurity.

The company was founded by Nir Zuk, the founder of Palo Alto Networks and a pioneer of modern firewall technology. He is joined by Wilson Xu, a former engineering leader at Palo Alto Networks, and Ehud Shamir, co-founder of SentinelOne.

Together, the team has decades of experience building security platforms that have shaped the modern cybersecurity landscape.

Why This Matters for the Cybersecurity Industry

Cylake’s launch highlights an important shift in how organizations will adopt AI-driven security in the coming years.

While many enterprises will continue to rely on cloud-native security platforms, others, especially those operating in highly sensitive environments, will require AI security solutions that run entirely within controlled infrastructure.

As AI becomes central to threat detection and response, the real competitive advantage will come from having access to the most complete and contextual view of security data. Cylake is positioning itself to help organizations achieve that visibility without exporting sensitive information to external platforms.

Looking Ahead

With $45 million in seed funding and a founding team with deep cybersecurity expertise, Cylake enters the market with strong momentum. Its infrastructure-first approach reflects the growing demand for security platforms that balance AI innovation with strict data control.

Execweb congratulates Cylake on this milestone. The company’s launch highlights an emerging category of cybersecurity solutions designed for organizations that require powerful AI analytics while maintaining full ownership of their data and infrastructure.
