PCM+ v4 Immunity Manager question?

[Cajuntank MS]

I know Immunity Manager is now part of the standard PCM+ v4 which I have, but is turned off by default. Some of the documentation for integration into IPS level devices is a little older and since I have my investment with Sonicwall UTM appliances (now Dell), I was wondering if I needed to look at doing something different in the near future. I don't want to keep pumping money into renewals on these appliances if they won't be supported in the future due to them being a direct competitor or HP going into a different direction with the techology.

Anyone using this technology and if so, is it working well for you?
