## Summary

Open-core cloud security graph platform mapping attack paths to sensitive data as open alternative to Wiz; built on Lyft's Cartography used by 70+ companies with no-agent read-only API setup.

## Company Overview

SubImage is a cloud security posture management (CSPM) platform built as the open-core alternative to enterprise security tools like Wiz — mapping cloud infrastructure to visualize attack paths to sensitive data and helping security teams prioritize which risks to fix first based on exploitability and blast radius. Built on top of Cartography, the open-source security infrastructure graph used by 70+ companies including Lyft, which open-sourced it, SubImage provides a fully hosted solution that connects to cloud accounts via read-only API access (no agents, no invasive installs) to immediately surface exploitable attack paths.

SubImage's graph-based approach models cloud infrastructure as a connected network — AWS accounts, GCP projects, IAM roles, EC2 instances, S3 buckets, databases, Kubernetes clusters — and traces the relationships between components to identify paths an attacker could follow from an exposed service to sensitive data stores. Rather than generating thousands of individual vulnerability findings (the alert fatigue problem plaguing security teams), SubImage prioritizes findings by showing which vulnerabilities are on the critical path to the organization's most sensitive assets.

In 2025, SubImage competes in the cloud security posture management (CSPM) and attack path analysis market with Wiz (the $12B cloud security unicorn), Orca Security, Lacework (acquired by Fortinet), and Prisma Cloud (Palo Alto Networks) for cloud infrastructure security visualization. Wiz achieved $350M+ ARR remarkably quickly by making cloud security accessible to security teams who aren't deep cloud experts — SubImage's "open-core alternative to Wiz" positioning targets the same buyer who wants Wiz-like functionality without the enterprise contract and complexity. The Cartography open-source foundation gives SubImage a credible technical lineage. The 2025 strategy focuses on the mid-market security teams who need Wiz-equivalent attack path analysis at a more accessible price point, deepening the open-source Cartography community, and building the remediation workflow integrations.
