Effective date

September 03, 2025 (UTC+8)

New billing rule

Under the new billing structure, The billing rules for the SecurityAudit have been adjusted; billing rules for other items remain unchanged.

All instances are billed based on actual usage × unit price, with a minimum hourly charge of USD 0.1042 per instance. If the calculated hourly charge is below the minimum, it will be automatically adjusted to the minimum (for example, if an instance’s calculated hourly charge is USD 0.10, it will be billed at USD 0.1042). Minimum daily charge: each instance is billed at least USD 2.50 per day (USD 0.1042 × 24 hours).

For unit pricing details, see Billing details.

Justification

Resource assurance and service stability

The security audit service requires dedicated cloud computing, storage, and network resources to provide real-time analysis and processing capabilities. These resources are allocated on a per-instance basis. Even for instances with low log volumes, a minimum amount of resources must be reserved to maintain normal operation and ensure service stability and immediate availability.

Improved service quality

A more reasonable minimum billing rule allows for continuous investment in optimizing the performance, reliability, and analysis capabilities of the security audit service. This ultimately provides you with a better security experience.

Impact on customers

This change applies to all instances using the DAS Enterprise Edition security audit feature.
