There are many network traffic analysis tools out there but how many of them understand industrial protocols like Modbus, Profibus or DNP3? More importantly, how effective are these solutions in the industrial control systems environment?

Please note that this space moves quickly so the list may not be up-to-date by the time you are reading this. That being said, I hope it provides a high-level overview of vendors and capabilities in this space.
