Re: Question re: load balancers as a security device
From: bugtraq () cgisecurity net

While I'm not promoting it for a security solution some load balancers do support URL based filtering 
(Netscalers). This can be useful for *very specific* web worms/abuses however is not a WAF (which I'm not
promoting :p)

Load balancers do not provide any type of security.  Load balancers
will only distribute the traffic and not deny it.  If your ISP manages
all the security devices between you and the hosting facility then at
a minimum you will want to put an additional firewall on your side so
you can have some control of what accesses your network over this site
to site tunnel.  This will probably be easier (politically not
technically) in a lager company.

  
Some Load Balancers include IPS in their devices with additional license.

Examples:

Radware: LinkProof and AppDirector --> www.radware.com
Nortel: NAS (Nortel Application Switch - Older Alteon)
