Billing method

Last Updated: Feb 07, 2018

Billing description

Billing type: Mixed

Unit: USD

Billing item: Basic protection and Elastic protection

Payment option: Subscription or Pay-As-You-Go

Billing cycle: Basic protection bandwidth (Unit: Gbps) and HTTP Flood protection capacity (Unit: QPS) are charged either monthly or yearly. A subscription bill is generated at purchase.

Settlement cycle: Elastic protection bandwidth (Unit: Gbps) and HTTP flood protection capacity (Unit: QPS) are charged daily. A Pay-As-You-Go bill is generated based on the actual attack peak that exceeds the basic DDoS protection capacity or HTTP flood protection capacity (only the larger billing range is counted) on the day before.

Expiry description

You are sent reminder text messages/e-mails to renew your service seven days, three days, and one day before your upcoming expiry service.

If you fail to renew the service after its expiry, the Anti-DDoS Pro service will be restored to the Anti-DDoS Basic protection capability.

Your Anti-DDoS Pro configurations are retained for seven days after your service expires. If you renew the service within seven days, the protection continues without interruption. However, if the service is not renewed during this seven days grace period, your previous Anti-DDoS Pro IP gets auto released and the previous service configurations becomes unavailable.


Basic protection

The monthly subscription pricing of basic protection is as follows.

  • International ISP provides Hong Kong, Singapore, and US East three lines, and supports up to 100 Gbps elastic protection capacity.

  • HTTP flood protection capacity is the protection capacity against HTTP flood attacks. If your normal business consumes a large number of QPS, choose an appropriate package accordingly.

Elastic protection

The daily Pay-As-You-Go pricing of elastic protection is as follows.

DDoS attack peak HTTP flood attack peak Elastic protection fee (daily)
Attack peak≤20 Gb Attack peak≤60,000 QPS Covered by monthly basic protection package
20 Gb<Attack peak≤30 Gb 60,000 QPS<Attack peak≤100,000 QPS 265
30 Gb<Attack peak≤40 Gb 100,000 QPS<Attack peak≤130,000 QPS 463
40 Gb<Attack peak≤50 Gb 130,000 QPS<Attack peak≤160,000 QPS 660

  • Daily Pay-As-You-Go pricing of elastic protection is calculated for each individual Anti-DDoS Pro instance that has the elastic protection capacity enabled. If more than one Anti-DDoS Pro instances are attacked, then all the affected instances are charged.

  • Elastic protection payment is calculated based on the actual attack peak that exceeds the basic DDoS protection capacity or HTTP flood protection capacity (only the larger billing range is counted) one day before.

  • If you do not want to enable elastic protection, set the elastic protection bandwidth to the same as the basic protection bandwidth. After this action, Anti-DDoS Pro instance will no longer have the elastic protection capacity.


The Anti-DDoS Pro service is subject to the following limits:

Specification Limit Description
Bandwidth 100 Mbps/instance Bandwidth consumed by normal business traffic in non-DDoS attack status.
four-layer forward volume 50/IP address Number of entries supported by TCP/UDP forwarding.
Seven-layer forward volume 50/IP address Number of entries supported by HTTP/HTTPS forwarding.
Note: Wildcard domain name forwarding is supported and only occupies one forwarding entry.
Number of servers protected 20 servers/instance The total number of different IP addresses configurable for four-layer and seven-layer configuration.

Note: The preceding plans are only available online. To meet the growing demands of your business, you can Contact sales for a customized solution.
