The threat level stated by MI5 – currently set at “Substantial” – is a generic term that’s meant to suit everyone. The simple word and its definition is meant to set the frame of events.
If it’s likely to take place, which at present it is, it’s supposed to be met with efficient use of force. The target could be anything but the response meets the use of physical intimidation.

The nature of cyber attacking, for example, goes beyond a virus per se, to the way in which a demand is made. The fact of a digital disease isn’t it. The level of immunity is the point here.
If the threat level is high enough, efforts to destabilise us happen most of the time. Our ability to challenge it varies. The threat level says what’s involved in avoiding it in part, or entirely.
