Cisco IPS 4255 fail-open

[rakyomin78]

I am looking at the datasheet of IPS 4255 and found that for automated fail-open a third party product is required I do not understand what third party is needed does this mean that IPS4255 does not do fail-open when the sensor fails? I could not find the recommended third party product from the datasheet as well... Perhaps someone can enlighten me?
