The service is billed per usage. Charges are calculated based on actual usage and are included in the invoice for the upcoming billing period. The service is billed as follows:
A fixed monthly fee for each firewall instance
Charges for permitted outbound traffic through the firewall, calculated monthly based on amount of data used (in GB). Rejected traffic is not billed
Outbound traffic is billed separately for the firewall and the dedicated server, with no mutual offset
The service can be canceled at any time. Any outstanding payments must be paid up to the deletion date.
