Thank you for your support of Alibaba Cloud. The Security Center will undergo a server-side public IP address change on October 12, 2026. After the change, the Security Center servers will use new public IP addresses.

If you have configured network policies to control the network path from your protected hosts to the Security Center servers, you must update these policies to allow traffic to the new public IP addresses. Otherwise, the host security capabilities of Security Center will become offline and ineffective.

If no such network policies are configured, no action is required.
