Security features do exist, and they're mostly common with other switches. What makes these switches unique is the ability to see application layers on the switch, but not directly through the switch. There are tools from Extreme Networks that allow visibility of such traffic, which other switches lack.
Extreme CloudIQ analytics can analyze all the traffic on Extreme Switches up to layer seven, offering full visibility. However, this tool is necessary for such detailed analytics and might not be compatible with some third-party products.
