There are varying techniques in achieving performance, and FPGAs/ASICs
are not the only way.
The company I work for, iPolicy Networks, put the development effort on
the front end to optimize rules, signatures, and processing rather than
building a better ASIC. We've been able to achieve 140Mbps - 2Gbps on a
single standard Intel platform without FPGAs by pre-compiling the rules
into a state engine, and pushing them down to an Intel platform.
On the high end to reach 4Gbps we used clustered Intel Network
Processors. Again, no custom ASICs required, just intelligent parallel
processing, and pre-compilation with bounded rules.
As to the total number of vendors, Gartner said last year there were
over 700 vendors in the security space. And it seems everyone messages
the same thing whether or not they can do it.

Subject: Re: IPS technology question.
I don't get, what do you mean by "Percentage", since we have uncounted
number of vendors/brands of IPS today.
If you look at the technology angle, the vendors who are offering both
Software and Appliance versions of the same IPS, falls into the first
category. To take a look back at the market, we find only very few
vendors, like ISS, Snort, Dragon, ...hmmm.. Can somebody help to
fill-up the list.
Whether it is IDS or IPS, it is important to look at the Detection
Technology. If it cannot detect, how can it alert or prevent?
In an IPS world, firewall plays behind the scenes; since the IDS is
configuring the built-in firewall feature to block.

Greetings.
What percentage of the IPS systems are out there, which does not use
co-processors/FPGA etc..
What percentage of the IPS systems depend on firewalls like iptables
and ip filter ?
I am just trying to get an idea of what is the state of art in the IPS
technology space.
Any information is appreciated.
Thanks
