A timeline view of network and asset change events

Logbook shows you a timeline view of network and asset change events. When someone spins up a host anywhere in the world that is connected to your organization in any way, Censys detects that host and reports it in the timeline view.

Logbook quickly reveals any new or suspicious assets tied to your company.

Complex IT Infrastructure

Your IT infrastructure is complex, distributed, and dynamic - more groups in your organization now have the authority to make changes to IT. In order to be both compliant and as secure as possible, you need to stay on top of these updates. Logbook automatically tracks changes to your IT for you.
