-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1So Andrew, are you saying that most of our customers routinely experience 75% hardware failure rates and we're somehow managing to cover this up or do you think this was an isolated incident? Can you imagine the cost to us in in terms of overhead for our customers with 100+ sensors if that were a true indication of the reliability of our gear?
BTW, our IPS appliances offer zero power fail-open NICs as well. -Marty On Feb 6, 2006, at 11:04 AM, Andrew Plato wrote:
Most of these devices are pretty good for reliability. The only exception I would make is SourceFire, which back when we sold it hadabysmal reliability (3 out of 4 boxes we sold to a customer show up deador died soon after installation).TippingPoint sells a zero-power bypass add-on for their IPS. If the IPSfails in anyway, traffic is passed through the zero-power device. Its very easy to add. Juniper does something similar. ----------------------------------------------- Andrew Plato, CISSP, CISM President/Principal Consultant Anitian Enterprise Security ----------------------------------------------- -----Original Message----- From: geek_brigades () yahoo com [mailto:geek_brigades () yahoo com] Sent: Thursday, February 02, 2006 8:27 AM To: focus-ids () securityfocus com Subject: IPS Reliability/Availability I am working on a big IPS project and I am very concerned about installing an inline device in a core enterprise network, where these devices have the potential to create big time network outages. Can you, please, share your possible bad experiences about the reliability of the following inline IPS products: ISS TippingPoint Juniper IPS Sourcefire McAfee IntruShieldHave you had any issues with the availability of these devices, such asfail close crashes or do you have any experience with bypass switches that would mitigate the availability issue?
