I have no idea about that security app, but I bet it's seeing both your 
native and VLAN frames.  A VLAN will have the same MAC address as the 
native.  Your choices would be to see if you can block that VLAN from 
reaching that computer, possibly with a managed switch, or maybe there's 
some option within that app to ignore a specific MAC.
