How many IPs are required for this solution – as many as was needed for our SD-WAN package? Are there any hardware upgrades required for an existing environment?

The number of IPs currently used by an existing customer remain the same with the Bigleaf DDoS Mitigation service. No additional hardware upgrades are needed. For customers who subscribe to a new Bigleaf SD-WAN package and add on Bigleaf DDoS Mitigation, the number of IPs required are the same as if they subscribed only to Bigleaf SD-WAN.
