AWS GuardDuty is a threat detection service that continuously monitors AWS accounts and workloads for malicious activity, unauthorized behavior, and anomalies using machine learning and threat intelligence.

GuardDuty is available in AWS China regions; however, threat intelligence feeds and automated detection rules may lag slightly behind global regions. It operates under separate terms, and intelligence updates are region-localized. Companies working cross-border use GuardDuty China supplemented by local security services.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
