Plans of Anti-DDoS Premium
- Insurance Plan
Each month, Anti-DDoS Premium Insurance Plan offers two advanced mitigations by default, featuring unlimited mitigation capabilities. This protects your businesses against DDoS attacks with full capacity within 24 hours after an attack has been detected, and consumes one advanced mitigation. The number of advanced mitigations is reset to two at the beginning of every month during the service period.Note To purchase more advanced mitigations, see Global advanced mitigation.For example, a protected IP suffers DDoS attacks at 11:20:00 (UTC+8), September 12, and an advanced mitigation is triggered. Within 24 hours, Anti-DDoS Premium provides unlimited mitigation capacities for this IP. The protected IP suffers another DDoS attack at 18:50:00 (UTC+8), September 13, and an advanced mitigation is triggered again. 24 hours later, the advanced mitigation stops and the two advanced mitigation of the Anti-DDoS Premium Insurance Plan instance in September are exhausted. The number of advanced mitigations is automatically reset to two at the beginning of the following month, October 1.
Insurance Plan is a basic solution of Anti-DDoS Premium and applies to users who are less vulnerable to attacks.Note Only when the DDoS attack against your business exceeds a specific threshold, namely the basic mitigation threshold, will the advanced mitigation of Anti-DDoS Premium be enabled.
