I was wondering what are are using for DDOS protection in your networks. We are currently evaluating different options (Arbor, Radware, NSFocus, RioRey) and I would like to know if someone is using the cloud based solutions/scrubbing centers like Imperva, Prolexic, etc and what are the advantages/disadvantages of using a cloud base vs an on-premise solution. It would be great if you can share your experience on this matter.
On-premise solutions are limited by your own bandwidth. Attacks have been publicly reported at 400Gbps, and are rumored to be even larger. If you don't have that much network to spare, then packet loss will occur upstream of your mitigation. Having a good relationship with your network provider(s) can help here, of course.
If you go with a cloud-based solution, be wary of their SLA. I've seen some claim 100% uptime (not believable) but of course no refund/credits for downtime. Another provider only provides 20Gbps protection, then will null-route the victim.

Also how are folks testing ddos protection? What lab gear,tools,methods are you using to determine effectiveness of the mitigation.
Live-fire is the cheapest approach (just requires some creative trolling) but if you want to control the "off" button, cloud VMs can be tailored to your needs. There are also legitimate companies that do network stress testing.
Keep in mind that you need to test against a variety of attacks, against all components in the critical path. Attackers aren't particularly methodical, but will still randomly discover any weaknesses you've overlooked.
