Ive never seen ISS. I just remember a few years back seeing Sentarus and it seemed like the technology they were using modified snort and spade was very good but they had the ugliest management console with like pink and puke green colors.

I was impressed with what I could see demarc has done to it. Im using the 1.6 and the management console and it seems like they adopted that into Sentraus. The coloring scheme seems to be a big improvement too.
I realy not that bent on colors its just nice when you have a management console thats appealing and intuitive.
