What they do

Problem

Security teams lack clear visibility into what infrastructure assets they have and how those assets relate, making it hard to assess and reduce risk.

Solution

A managed, open-core infrastructure mapping platform built on the Cartography open-source project that discovers assets and maps their relationships.

Who it's for

Enterprise security teams responsible for cloud and infrastructure environments.
