SubImage
Clear maps for complex cloud environments
SubImage builds maps of your cloud environment to give you visibility on what assets you have and how they relate to each other. This enables any security team to deeply understand their environments and reduce risk.
SubImage is a managed offering built around the Cartography open-source project, and is founded by members of Cartography's original team.
