Two more options.  And for Netflow device - read that to mean Arbor or
its competitors.

5 Ditch the stateful firewall and exclusively use a netflow device

6. Outsource to a hosted DDoS mitigation service (Prolexic etc)

Do you -

1. Have (say) two firewalls in HA config?

2. Back your firewall with routing based measures, S/RTBH, blackhole
communities your upstream offers, etc [the standard nspsec bootcamp
stuff]

3. Simply back the firewall with a netflow based device?

4. Estimate that the risk of a DDoS that exceeds your firewall's rated
capacity is extremely low?  [and yes, 150k ++ connections per second
ddos is going to be massive, and relatively rare for most people]
