MX and OT Protocols

[INTERNAL-MX]

Hi Team, I hope you are well.

Please your comments in the following question:  Is there any reference about the applications and protocols supported by MX ?   I would like to know if the MX is able to detect and filter industrial protocols (OT).  Any links with protocol list or application list ? 

Thx in advance

Guillermo.

The MX (like any firewall) can pass all network traffic.

The MX uses NBAR for traffic/application classification. You can see a list of NBAR protocols at the link below.

If it is based on IP it will be able to pass it.  It probably won't be able to filter it unless it uses a specific TCP/UDP port.
