How Is WAF Billed?

Cloud WAF is billed on a yearly/monthly basis (prepaid), and dedicated WAF instances are billed on a pay-per-use basis. So WAF standard, professional, and enterprise editions are billed yearly/monthly as they are cloud WAF editions. For cloud WAF billed yearly/monthly, domain name, bandwidth, and rule expansion packages are provided at an extra cost. You will be billed for the WAF instance and expansion packages you selected based on the billing mode you specified.
