D/DoS mitigation hardware/software needed.

[jeffrey.lyon at blacklotus.net (Jeffrey Lyon)]

We have substantial direct experience with both RioRey and IntruGuard.
RR is more plug and play while IG is more robust but both are great.
Use a robust firewall such as a Netscreen in front of your mitigation
tool.

Best regards, Jeff
