Most of these devices are pretty good for reliability. The only exception I would make is SourceFire, which back when we sold it had abysmal reliability (3 out of 4 boxes we sold to a customer show up dead or died soon after installation).
TippingPoint sells a zero-power bypass add-on for their IPS. If the IPS fails 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: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, February 02, 2006 8:27 AM To: [email protected] 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 IntruShield Have you had any issues with the availability of these devices, such as fail close crashes or do you have any experience with bypass switches that would mitigate the availability issue?
