# Third-Party Blackhole

When an anti-DDoS device detects that the traffic of a specified IP address exceeds the blackhole threshold, the ATIC notifies the third-party device of executing a blackhole policy on the upstream network.

- Triggering a Blackhole Policy for the Third-Party System Through the RESTful API
  When an anti-DDoS device detects that the traffic of a specified IP address exceeds the blackhole threshold, the ATIC system sends an RESTful API notification to the third-party system for executing a blackhole policy on the upstream network.
- Triggering a Blackhole Policy for the Third-Party Device by Sending Syslogs
  Upon detecting that the traffic of a specified IP address exceeds the blackhole threshold, the anti-DDoS device automatically sends syslogs to the third-party device and the third-party device performs the action.
