Command Zero Platform is an AI-augmented security investigation and threat hunting platform designed for tier-2 and tier-3 security analysts, incident responders, and threat hunters in medium-to-large enterprises. The platform connects to an organization's existing cyber and non-cyber technology stack via read-only APIs using a federated data model, enabling analysts to query and investigate across data sources without requiring direct access or technology-specific expertise. Investigations are guided by embedded expert knowledge, which includes industry best practices, investigation templates, and organizational knowledge packs. Analysts can use pre-built or custom "facets" (dynamic playbooks) to automate investigative steps and standardize workflows. Large language models (LLMs) are integrated to assist analysts in interacting with connected systems, bridging knowledge gaps, and supporting decision-making across experience levels. Analysts can replay past investigations to support learning and development of best practices. The platform supports collaborative investigation workflows, allowing teams to build on each other's work, coach junior analysts, and pivot to relevant data sources during complex cases. Automated reporting, timelines, and verdict generation are included, enabling analysts to document findings, articulate impact, and present results to both technical and executive audiences. Use cases supported include general cyber investigations, identity-based investigations, business email compromise (BEC) and email investigations, and threat hunting. Pricing is based on the environment and team size; no free trial is available without contacting the vendor.
