People rely on usernames and passwords to identify them- selves to machines so they can access networks and data. Cryptographic keys and digital certificates identify and au- thenticate machines. As the number of machines increases— driven by digital transformation and the emergence of more machine types, including cloud workloads, virtual machines, containers, and Internet of Things (IoT) devices—these keys and certificates become more critical. Visibility is certainly one of the biggest challenges to effec- tive machine identity management. It’s that very first piece of knowing what’s there and wh
