Value proposition

Enables organizations to deploy advanced AI-driven cybersecurity capabilities while maintaining complete control and sovereignty over sensitive data and operations - removing the traditional trade-off between security innovation and data control

Products and solutions

["AI-Native Cybersecurity Platform","On-Premises/Private Cloud Security System","Hardware-Software Integrated Security Solution","Holistic Data-Driven Security Architecture","Agentic Protection System","Unified Security Platform with Complete Data Visibility"]

Unique value

First cybersecurity platform to deliver complete AI-native, agentic protection while operating entirely within customer-controlled environments (on-premises or private cloud), eliminating the need for public cloud dependency while providing next-generation security capabilities.

Target customer

Highly regulated organizations, governments, defense contractors, and large enterprises that cannot move sensitive data off-premises due to regulatory, operational, or national security constraints

Industries served

["Government and Public Sector","Defense and National Security","Healthcare and Life Sciences","Financial Services","Critical Infrastructure","Highly Regulated Industries","Enterprise Security"]

Technology advantage

Combines three critical differentiators: (1) Holistic architecture with complete visibility across all organizational data and infrastructure layers, (2) Unified platform approach eliminating fragmentation from multiple disconnected security tools, and (3) Full data sovereignty without sacrificing access to the most advanced AI-driven cybersecurity capabilities - all built on a single data foundation with hardware and software components.

How they differentiate

First AI-native cybersecurity platform designed specifically for complete data sovereignty - operates fully on-premises or in private clouds without ANY public cloud dependency, unlike competitors who primarily focus on cloud-first models. Combines hardware-software integrated approach with agentic protection and holistic data visibility across all infrastructure layers, targeting the ~1/3 of the market (governments, defense contractors, highly regulated industries) left behind by cloud-first security vendors.

Main competitors

["Palo Alto Networks","SentinelOne","CrowdStrike"]

Key partnerships

["Greylock Partners (Lead investor - $45M seed round)","Select group of design partners for platform development","Additional experienced technology investors"]

Major milestones

["Company launch announced March 5, 2026 from stealth mode","$45M Seed funding secured - led by Greylock Partners","Founded by Nir Zuk (Palo Alto Networks founder/CTO for 20 years)","Co-founders include Wilson Xu (former Palo Alto Networks engineering lead) and Ehud (Udi) Shamir (SentinelOne co-founder)","Platform architecture defined for AI-native, data-driven cybersecurity with complete data sovereignty"]

Growth metrics

Just launched March 5, 2026 - currently in development phase with select design partners; commercial availability anticipated early 2027. Company is collaborating with design partners during pre-product phase.

Market positioning

Early-stage contrarian challenger targeting underserved enterprise segment - specifically organizations that cannot use public cloud-based security due to regulatory, operational, or national security constraints. Founded by legendary cybersecurity entrepreneur Nir Zuk (Palo Alto Networks founder) to address a 'hundred billion dollar plus opportunity' in on-premises AI security that cloud-first vendors have largely ignored.

Geographic focus

United States (headquartered in Sunnyvale, California), Israel (founder background and likely R&D presence), with planned focus on North America, Europe, and allied nations requiring data sovereignty

Patents and IP

No registered patents disclosed as of launch date
