SubImage is a fully managed offering built around the Cartography open-source project, created at Lyft in 2019 and donated to The Linux Foundation in 2024.

Founded by members of the original Cartography team, SubImage helps organizations focus limited resources on the risks that matter by mapping attack paths and weak points leading to sensitive data in the same way an attacker would.
