Having experienced the frustrations of poorly designed/executed interfaces first-hand, one of the most valuable features for me is the graceful, responsive, and compatible web-UI. It works well across all browsers that I’ve tried, and even on mobile browsers. The snort engine, which is the muscle behind the Sourcefire IPS technology, has always been a joy for me to work with. I have almost 10 years of experience with snort and the power, customization, and ease-of-use has yet to be replicated. Lastly, I find great value in the context-sharing behavior across technologies with Sourcefire. Each active technology on the sensor enjoys access to the context of the others, and this has the great benefit of increasing accuracy and efficacy of automated response functions.
