Shield Alert Events

Box Shield must be purchased and enabled on a Box enterprise in order to take advantage of the advanced security offerings outlined below.

Threat detection alerts

Shield threat detection delivers context-rich alerts on potential threats, such as compromised accounts and data theft, based on anomalous user behavior.

The possible alerts produced by Shield are for:

  1. Suspicious locations
  2. Suspicious sessions
  3. Anomalous downloads
  4. Malicious content

All Shield threat detection alert events are produced within the enterprise event stream. These events follow the standard event object schema and the event_type value is set to SHIELD_ALERT.
