Command Zero is a cybersecurity company that develops an AI-powered investigation platform designed for Security Operations (SecOps) teams. The platform focuses on accelerating and standardizing cyber incident investigations by combining expert content, large language model (LLM)-based automation, and a user-led interface. The core product addresses what the company identifies as a bottleneck in security operations: the investigation phase of incident response. Unlike traditional SOAR (Security Orchestration, Automation and Response) solutions, which rely on predefined playbooks for known alert patterns, Command Zero is built to handle novel and previously unseen threat patterns. The platform aggregates and operationalizes institutional knowledge from past investigations, enabling analysts of varying skill levels to conduct expert-quality investigations. Key capabilities include automated and user-led investigation workflows, LLM-based reasoning trained on real incident data, structured verdicts with detailed timelines and audit-ready reports, and integration across hybrid enterprise environments including cloud and SaaS. The platform captures and encodes incident response knowledge — including hundreds of common investigator questions — and makes this expertise available at scale without requiring a dedicated security engineering team for maintenance. Command Zero's target market includes enterprise security operations teams and managed security service providers. The company is backed by venture capital firms Andreessen Horowitz (a16z) and Insight Partners, along with a number of individual investors from the cybersecurity industry. The founding team includes Dov Yoran (CEO), Dean De Beer (CTO), and Alfred Huger (CPO).
