Security Center:[Notice] Changes to Cloud Threat Detection and Response (CTDR) billing

Last Updated:Jun 08, 2026

Security Center updates the billing model for Cloud Threat Detection and Response (CTDR). Analysis and handling capabilities (alerting, event handling, and SOAR) are now decoupled from log storage, so you can purchase log storage capacity separately.

Effective date

09:00 on April 22, 2024 to 18:00 on April 26, 2024 (UTC+8).
