IPS license

[Jesus_Cano]

Hi,

We have a perimetral FW. We are thinking in buying IPS license in order to avoid attacks from outside. So i would like to clarify the next subjects about IPS license.

-License -> IPS license
- Performance -> Enabling this feature what minimum requisites are needed? We dont want to have issues about CPU/,memory .....
-Administration -> Is it necessary many work hours to configure IPS blade (signatures...)? or is almost "plug a play"

thanks a lot
