Oh, I didn't say they didn't exist.
A good way to get started w/scalable DDoS mitigation is to implement S/RTBH
on one's hardware-based edge routers, and then make use of open-source
NetFlow tools for visibility.
There are commercial solutions as well - in the interests of full
disclosure (pardon the pun, heh), I work for a vendor of such intelligent
DDoS mitigation (IDMS) solutions.
These slides may be of interest in hardening/leveraging one's network
infrastructure and gaining the ability to
detect/classify/traceback/mitigate DDoS:

There was also a relevant talk at the latest NANOG (a synopsis of
discussions on nanog-l and cisco-nsp):

and other relevant presentations at various NANOGs in the past.
To answer the previous respondent's question, Cisco acquired Riverhead and
its Guard in early 2004:

I also highly recommend this book by Dave Smith and Gregg Schudel of Cisco
- it's the best (and only!) book on real-world opsec out there, available in
dead-tree, Kindle, and Adobe Reader formats:

[Full disclosure again; I'm cited in the book, but received and continue to
receive no renumeration of any kind due to same.]
But before going the commercial route, folks should work on hardening their
hosts/OSes/apps and leveraging their existing infrastructure and open-source
as noted in the presentations above - in many cases, this is all that's
needed, as outlined here:
