SubImage is a San Francisco–based company providing an open-core cloud security graph to enterprise security teams. The platform automatically maps an organization’s entire cloud infrastructure, highlighting exposed assets, misconfigurations, and prioritized issues. Security teams leverage the graph to remediate vulnerabilities, assign ownership, and respond to incidents faster. The company was co-founded by security veterans Alex Chantavy and Kunaal Sikka, who previously worked on security teams across government, enterprises, and hypergrowth startups. With its recent $4.2 million seed financing, SubImage plans to grow its engineering organization, expand customer pilots, and roll out new product features. No revenue, user, or other operating metrics have been disclosed.
