IDS: RE: IPS Reliability/Availability

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.

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?

Thanks,
Mike
