Note: All third-party API integrations that are part of the Arctic Wolf® Managed Detection and Response (MDR) offering are designed with a polling frequency of approximately 15 minutes. Time-based events are polled with a 5-to-40-minute delay to ensure data availability within the third-party API endpoint. For new deployments, after the API integration is successfully configured with the necessary credentials, we begin polling and reviewing activity from approximately 1 hour prior to configuration success.

If credentials fail, for example, due to expired credentials, we notify you and request a new set of API credentials. After a polling failure, we only replay data for a period of 12 hours starting from when the refreshed credentials are provided.
