A cybersecurity assessment system is provided for monitoring, assessing, and addressing the cybersecurity status of a hierarchy of target networks. The cybersecurity assessment system may scan individual target networks and produce data regarding the current state and properties of devices on the target networks. The cybersecurity assessment system may generate user interfaces to present cybersecurity information regarding individual target networks, and composite cybersecurity information regarding a hierarchy of target networks or some subset thereof. The cybersecurity assessment system can generate access configurations that specify which cybersecurity information of the hierarchy can be accessed by individual target networks of the hierarchy.
