As its largest acquisition to date, Palo Alto will pay $670 million in cash and stock and approximately $130 million in equity awards.

Expanse’s platform provides customers with a vulnerability map of externally exposed and untracked assets and helps evaluate and mitigate risk.

Following the acquisition, Expanse’s attack surface management capabilities will be integrated into the Palo Alto Cortex suite to help security operations stitch together external and internal threat data and provide customers with an integrated view of the enterprise.
