We aren't allowed to use VGA because it's vulnerable to being sniffed. Everything has to be hdmi or display port/mini display port

It depends on the threat profile. In an emissions secure zone, inside a big metal box like say a ship, the chance of a bug in the monitor's hdmi circuitry can be higher than the risk of the vga being sniffed.

Funnily enough a static configuration HDMI display needs no special circuitry, as it's essentially VGA that didn't pass a DAC and you can spam it directly to LCD matrix.

If theres a chance of there being a bug in the HDMI circuitry isn't there just as much chance of there being a bug in VGA?.
