    Hi David,

    A standard PCI bus (PCI-X, 133Mhz) is only capable of 1.06Gbps. This means
    530Mbs in, and 530Mbs out, not taking into account things like hard-disks,
    logging/reporting and any packet inspection, which only serve to pull this
    number down further.
    It is architecturally impossible for a standard Intel platform to attain a
    throughput of anything higher than 530Mbs, let alone the 2Gpbs you claim
    below?
    A further explanation of these figures may help clear things up?

    Regards,

    Tim

    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.

    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.
