Data Security Center:Billing

Last Updated:Jul 14, 2026

Billing overview

Data Security Center (DSC) provides data security capabilities for your cloud data assets, such as ApsaraDB RDS and Object Storage Service (OSS). These capabilities include sensitive data discovery, data audit, and threat detection.

DSC charges consist of an edition fee and the Value-Added Service Fee. DSC supports subscription (prepaid) and pay-as-you-go (postpaid) billing modes. Subscription is the default mode. After elastic scaling is enabled, when the prepaid quota is exhausted, the system automatically switches to pay-as-you-go billing. Excess usage beyond the prepaid quota is billed daily based on actual consumption.

  • Edition fee: The base fee for using DSC. You select an edition, such as Premium or Enterprise, that determines the data security capabilities available to you.

  • Value-Added Service Fee: An additional fee that applies when the default quotas of your edition, such as the number of database instances or the storage capacity available for scanning, do not meet your business requirements. You can purchase additional capacity or enable extra features as needed.

Postpaid billing items

After elastic scaling is enabled, when the prepaid quota for the following features is exhausted, the system automatically continues to provide the service at pay-as-you-go prices. Excess usage is billed daily based on actual consumption. Currently, only Data Identification - Database Table Quantity, Data Identification - Storage Identification Capacity, AI Text Detection, and AI Image Detection support pay-as-you-go billing. All other features support only subscription billing.

Elastic scaling

After elastic scaling is enabled, when the prepaid quota of your DSC instance is exhausted, the system automatically continues to provide services in pay-as-you-go mode. Identification, detection, and other tasks are not interrupted. Excess usage beyond the prepaid quota is billed daily at pay-as-you-go prices, and bills are pushed the next day.

How to enable

  • New users: Elastic scaling is enabled by default after you purchase a DSC instance. No additional configuration is required.

  • Existing users: Log on to the Data Security Center console. On the Overview page, click Upgrade to upgrade your instance. Elastic scaling is automatically enabled after the upgrade.

  • When elastic scaling is enabled, the system automatically continues services when the prepaid quota reaches the limit. No manual scaling is required. Classification, grading, data auditing, and other tasks run without interruption.

  • When elastic scaling is not enabled, related services are suspended after the prepaid quota is exhausted. Services resume only after you manually Upgrade to add more quota.

  • Pay-as-you-go bills are pushed the next day. You can view detailed usage and charges on the Expenses and Costs console's Bill Details page.

Billing for related products

Adding data assets to DSC may incur fees for reading data and storing audit logs. These fees are charged by the corresponding cloud services to the account that owns the assets.

For example, when you enable native log collection for OSS assets, DSC creates a dedicated project in Simple Log Service (SLS). The default data retention period for the Logstore in this project is 7 days.

  • If the data in the Logstore does not exceed 900 GB and the retention period does not exceed 7 days, no storage fees are incurred.

  • If the retention period exceeds 7 days or the data exceeds 900 GB, storage fees are charged by SLS to the account that owns the assets.

For more information, see Billing for related products.

Bills and cost management

View usage and bills

You can view DSC resource usage and billing details in the Alibaba Cloud console.

  • View usage: Log on to the Data Security Center console. On the Overview page, view the specifications and expiration time of your instances.

  • View bills: Log on to the Expenses and Costs console's Bill Details page. Select Data Security Center as the product to view and download your bills. For specific steps, see Bill Details.

Change instance specifications

  • Upgrade: If your current DSC edition or specifications do not meet your business requirements, go to the Overview page of the Data Security Center console and click Upgrade to adjust instance specifications. You must pay the price difference between the new and existing configurations. For more information, see Upgrade an instance.

  • Downgrade: DSC does not support downgrades. If you have special downgrade requirements, contact your account manager for assistance.

Renew an instance

To ensure continuous security protection, renew your DSC instance before it expires.

  • Expiration reminder: The system sends reminders by text message, email, and other channels 7 days before your instance expires.

  • Impact of expiration: After an instance expires, it enters the Expired state. The system retains all configurations and data for 15 days after expiration. If you renew within this period, the service resumes. If you do not renew within 15 days, the DSC instance and all its configurations and data are permanently deleted and cannot be recovered.

  • How to renew: On the Overview page of the Data Security Center console, click Renew Subscription.

For more information about renewal rules and procedures, see Renew an instance.

Unsubscribe from an instance

  • Newly purchased DSC instances, including the DBAudit (Classified Protection Compliance Edition), are eligible for a 5-day unconditional refund. You can unsubscribe on the unsubscription page. Instances used for more than 5 days are not eligible for unconditional refunds.

  • For renewal orders, you can request a 5-day unconditional refund before the new service cycle begins. After the new service cycle starts, refunds are not supported.

For more information, see Refund policy.

Overdue payments

When your account balance is insufficient, your account enters an overdue state. Since DSC uses subscription billing, existing instances continue to function normally within the subscription period. However, you cannot upgrade instances, renew subscriptions, or purchase other resources until the overdue payment is settled.
