Billing
The prices of billable items that are provided in this topic are for reference only. The actual prices on the Anti-DDoS Proxy (Outside Chinese Mainland) buy page shall prevail.
Total fees = Subscription instance fees + Pay-as-you-go fees.
Part 1: Subscription instance fees
Subscription instance fees = Basic instance fees + Fees for upgradable configuration items
Basic instance fees
Instance type | Unit price (USD/month) |
Sec-CMA 1.0 | 15,480 |
Sec-CMA 1.0 (Basic Edition) | 9,288 |
Sec-CMA 2.0 (Insurance) | 15,480 |
Sec-CMA 2.0 (Unlimited) | 36,843 |
The basic instance fees correspond to the default minimum specifications. The four instance types share the same default specifications, as shown in the following table. You can also upgrade the specifications of configuration items as needed.
Specification name | Sec-CMA specifications | Billing method | Description |
Clean bandwidth | 10 Mbit/s | Subscription | The maximum service traffic that the instance can process when no attacks occur. The specification is scalable. |
95th percentile burstable clean bandwidth pattern | Disabled | Pay-as-you-go | Pay-as-you-go charges are incurred if the actual bandwidth is greater than the clean bandwidth but less than the 95th Percentile Burstable Clean Bandwidth. |
Clean queries per second (QPS) | 500 | Subscription | The maximum rate of concurrent HTTP and HTTPS requests that the instance can process when no attacks occur. You can upgrade the specification. Note Set the Clean queries per second (QPS) based on your actual service usage. If your service usage exceeds the purchased QPS specification, packet loss can occur and full logs may be incomplete. |
95th percentile burstable QPS | Disabled | Pay-as-you-go | If the actual QPS is greater than the clean QPS but less than the 95th percentile burstable QPS, pay-as-you-go bills are generated. |
Function plan | Standard | Subscription | Includes Standard and Enhanced function plans. The Enhanced function plan provides advanced service access and DDoS attack mitigation capabilities. For more information, see Differences between the Standard and Enhanced function plans. |
Number of protected domain names | 10 | Subscription | The number of HTTP and HTTPS domain names that the instance supports. This limit is scalable. One root domain is supported for every 10 domain names. For example, if an instance supports 50 domain names, they can belong to a maximum of 5 root domains. |
Number of ports | 5 | Subscription | The number of TCP and UDP ports that the instance can protect. This limit can be increased. |
Fees for upgradable configuration items
Clean bandwidth
Price for every 10 Mbit/s of clean bandwidth increment: USD 1,548 per month
Clean QPS
Clean QPS
Unit price (USD per QPS-month)
0 < QPS ≤ 500
0
500 < QPS ≤ 5,000
1.5
5,000 < QPS ≤ 8,000
1.425
8,000 < QPS ≤ 10,000
1.35
10,000 < QPS ≤ 50,000
1.275
50,000 < QPS ≤ 100,000
1.05
For example, if you set Clean QPS to 6,000 when you purchase an instance, the monthly fee for the Clean QPS specification is calculated as follows:
(500 - 0) × 0 + (5,000 - 500) × 1.5 + (6,000 - 5,000) × 1.425 = USD 8,175
Function plan
Enhanced function plan: USD 1,200 per month
Number of protected domain names

For example, if you purchase an instance that uses the Standard function plan and set the number of protected domain names to 600, the monthly fee for the number of protected domain names is calculated as follows:
(10 - 0) × 0 + (500 - 10) × 4.5 + (600 - 500) × 4.1 = USD 2,615
Number of ports
Number of ports
Unit price (USD/port/month)
0 < Number of ports ≤ 5

50 < Number of ports ≤ 100
26
100 < Number of ports ≤ 500
22
500 < Number of ports ≤ 1,500
18
For example, if you set the number of ports to 80 when you purchase an instance, the monthly fee for the number of ports is calculated as follows:
(5 - 0) × 0 + (50 - 5) × 30 + (80 - 50) × 26 = USD 2,130
Part 2: Pay-as-you-go fees
You can enable pay-as-you-go features as needed. After you enable a pay-as-you-go feature, bills are generated only if the usage meets the billing conditions.
Feature | Billing method | Description |
95th Percentile Burstable Clean Bandwidth | Daily or monthly pay-as-you-go | The burstable clean bandwidth feature provides additional clean bandwidth for your instance. It prevents your service from being rate-limited when traffic spikes exceed the instance's clean bandwidth during peak hours. For more information, see Billing of the burstable clean bandwidth feature. |
95th percentile burstable QPS | Daily or monthly pay-as-you-go | Burstable QPS provides additional clean queries per second (QPS) for your instance. This prevents your service from being rate-limited if traffic spikes during peak hours and your clean QPS exceeds the instance specification. For more information, see Burstable QPS billing. |
Expiration policy
Time period | Service traffic forwarding | Instance configuration |
Within 6 calendar days after the expiration date |
| The instance retains its configuration. |
From 7 to 14 days after the expiration date | The instance no longer forwards service traffic. Warning If you no longer use Sec-CMA, switch service traffic from the Anti-DDoS instance to the origin server at least 7 calendar days before the instance expires. For website services, ensure that your domain name resolution does not point to the CNAME of the Anti-DDoS instance. For non-website services, ensure that your services do not use the exclusive IP address of the instance. Otherwise, your service will be interrupted when the instance expires. | The instance retains its configuration. |
On Day 15 after the expiration date | The instance stops forwarding service traffic. | The instance is released. Warning After all Anti-DDoS Proxy instances under your account are released for 30 days, the system automatically clears all associated domain and port forwarding rules. The 30-day countdown starts from the release of the last instance. |
