I manage a network of 60 nodes. We are looking at the watchguard 750 bundle. we currently have an older version of their technology that does not support all of the features. does anyone have any reviews of the gateway spam filter and the mcafee asap service? or can anyone recommend a better product. We looked at sonicwall but the rep told me that she doesnt recommend using the spam filter built in and we should use a seperate device for spam filtering.
