It continually\nanalyzes and evaluates your security telemetry against Indicators of Compromise\n(IoCs) curated by Mandiant threat intelligence.\n\nWhen ATI is enabled, Google Security Operations ingests IoCs curated\nby Mandiant threat intelligence that have an [Indicator Confidence Score](https://cloud.google.com/chronicle/docs/detection/understand-ic-score) (IC-Score) greater than 80. When a match is found, an alert is generated. You can then investigate the IoC on the **IoC matches** page, which displays possible IoC matches for domains, IP addresses,\nfile hashes, and URLs. Information about the IoC is displayed, including:\n\n- GCTI priority\n- IC-Score\n- Associations\n- Campaigns\n\nYou can also view detailed information about the events that triggered the IoC match, information from the threat intelligence source,\nand the rationale for the IC-Score. For more information, see [View IoCs using Applied Threat Intelligence](/chronicle/docs/detection/ati-view-ioc-page).\n| **Important:** Applied Threat Intelligence in Google SecOps is available with a Google SecOps Enterprise Plus license.\n\nGoogle SecOps curated detections evaluate your event data against\nMandiant threat intelligence data, and generates an alert when one or more rules\nidentify a match to an IoC with an *Active Breach* or *High* priority.\n\nTo use Applied Threat Intelligence, do the following:\n\n1. Enable the [Applied Threat Intelligence curated detections](/chronicle/docs/detection/ati-curated-detections).\n2. Investigate alerts using the [**IOC matches** page](/chronicle/docs/detection/ati-view-ioc-page).\n\nYou can also learn more about how the IC-Score is assigned in the [IC-Score overview](/chronicle/docs/detection/understand-ic-score).\n\n**Need more help?** [Get answers from Community members and Google SecOps professionals.](https://security.googlecloudcommunity.com/google-security-operations-2)"]]
