Re: IPS - Cisco vs. McAfee vs. Tippingpoint

[Gary Halleen <ghalleen () cisco com>]

Hurgel,

While I think you'll be happy with the features and performance of Cisco's
IPS (especially if you are using 7.0 software, which comes with Reputation
Filtering and Global Correlation capabilities), you should keep in mind that
an IPS is not always the best solution for DDoS protection.

Depending on the type and severity of the DDoS attack, the IPS may provide
what you are looking for, especially if you configure it to block or
rate-limit on an upstream device, like a router, switch, or firewall.

You may also want to take a look at Arbor's Peakflow products, as well as
Cisco's Guard/Detector products.  Both of these are designed with DDoS
protection as primary features.  They also are typically deployed both at
the customer's site, as well as upstream, so that DDoS traffic is never
eating up your bandwidth to the Internet once an attack is detected.
