In today’s hyperconnected and AI-enriched enterprise landscape, the security paradigm has fundamentally shifted. As companies continue to depend on cloud services such as Salesforce and Google Drive, and workers increasingly use AI tools, traditional perimeter defenses have become obsolete. Modern hackers no longer need to breach systems and encrypt files when they can simply intercept valuable data as it moves across platforms. This evolution in attack methodology has created an urgent, unaddressed gap in enterprise security, at a pivotal moment in which AI has cemented data as the lifeblood of every organization.
This challenge demands a fundamentally new approach, one that understands data not as static assets behind walls, but as dynamic resources constantly in motion across the digital ecosystem. As new communication channels emerge and AI reshapes daily work, enterprises need far more than a rules-based system — they need context and automation that operate at the speed of modern business. Enter Orion Security: The AI-powered data protection platform.
We’re thrilled to announce that Underscore VC has invested in Orion Security‘s $6 million Seed round alongside PICO Partners, FXP, and several cybersecurity leaders including the founders of Perimeter 81 and the CISO of Elastic. Based in Tel Aviv, Orion has emerged from stealth with a groundbreaking AI-powered approach to data protection that’s already being deployed by leading technology companies like Aqua Security and Incode.
Redefining Data Protection for the AI Era
Orion Security is fundamentally reimagining how organizations protect their sensitive information. While traditional Data Loss Prevention (DLP) tools rely on rigid rules and manual policies, Orion takes a revolutionary context-aware approach. Their platform automatically learns and understands the natural flow of data within an organization by connecting to cloud services, browsers, and devices to create a comprehensive map of business processes.
This innovation couldn’t come at a more critical time. With the proliferation of generative AI tools, data exfiltration risks have escalated dramatically — just ask Samsung, which banned employees from using ChatGPT after internal source code was leaked. The financial stakes are enormous: the average cost of breaches has risen to nearly $5 million in 2024, making data protection the top challenge for CISOs in dynamic cloud environments.
What makes Orion’s approach so transformative is their focus on understanding the operational DNA of each organization. By leveraging AI to map normal data flows and business contexts, their technology can accurately distinguish between legitimate activities and potential data theft, whether intentional or accidental, all without overwhelming security teams with false alerts. In an era where security teams are overwhelmed by alert fatigue, this is a crucial differentiator.
Orion’s architecture is designed to connect with existing security tools and modern cloud environments, making it easy to layer on top of current security infrastructure. This simplicity reduces friction for security teams already juggling a multitude of platforms.
The Team Securing Enterprise Data’s Future
At Underscore, we’re founder-first in our investment approach, and Orion’s founding team exemplifies the perfect combination of problem space expertise and solution execution. CEO Nitay Milner brings invaluable experience as a former product leader at Cisco-acquired Epsagon, giving him deep insight into observability and data tracing. CTO Yonatan Kreiner complements this perfectly with his background as the former application security lead at WalkMe. Together, they bring a rare combination of domain expertise, entrepreneurial grit, and a keen understanding of how AI can augment human intelligence.
Beyond their impressive backgrounds, Nitay and Yonatan have a shared commitment to building a product that’s both robust and user-friendly, which is a hallmark of startups that successfully navigate the enterprise security market. Their humility, adaptability, and relentless focus on customer needs give us full confidence they’re the right team to lead this transformation.
We were introduced to Nitay and Yonatan through our relationship with FXP. As Gil Zimmermann, Partner at FXP and former founder of CloudLock (acquired by Cisco), notes: “Orion’s AI-powered approach solves the core challenges we faced for years—the lack of business context and overwhelming manual work. This is the future of data security we envisioned but which couldn’t be built a decade ago.”
The team has already demonstrated impressive traction, securing adoption from technology leaders like Aqua Security and Incode. Their proprietary Indicators of Leakage (IOL) engine, which utilizes reasoning models to analyze patterns in data movement while leveraging LLM classification to understand context, represents a genuine breakthrough in the field.
What’s Next For Orion Security?
With this funding, Orion will expand their team and accelerate product development to address the growing demand for their solution. If you’re interested in joining Orion’s mission to transform data protection, they’re actively hiring across engineering, data science, and go-to-market roles. And if your organization struggles with protecting sensitive data across cloud platforms, we encourage you to explore how Orion’s innovative approach can help secure your business. Learn more here!
