The noun 'die Bedrohung' is derived directly from the verb 'bedrohen' (to threaten). The ending '-ung' turns the verb into a feminine noun that describes the action or the result of the verb.
Er hat seinen Nachbarn bedroht.
He threatened his neighbor.
To express what is endangered, use 'für' + accusative. To name the source of the danger, use 'durch' + accusative.
Die Dürre ist eine Bedrohung für die Landwirtschaft.
The drought is a threat to agriculture.
In this meaning, 'Bedrohung' is often combined with the verb 'darstellen' (to represent/constitute). The phrase 'eine Bedrohung darstellen' (to represent/constitute a threat) is a more formal way of saying that something is a threat.
Armut stellt eine ernsthafte Bedrohung für die soziale Stabilität dar.
Poverty represents a serious threat to social stability.
This meaning describes the concrete act of making threats and is often used in legal or police contexts. Typical verbs here are 'anzeigen' (to report/file charges) or 'ermitteln' (to investigate).
Sie hat die Bedrohung sofort bei der Polizei gemeldet.
She reported the threat to the police immediately.
safety / certainty / security
'die Sicherheit' and 'die Bedrohung' are often opposites. 'Sicherheit' means that you are protected and that there is no major danger. 'Bedrohung' means a threat or something that can harm someone; it can also be an intimidating action. In conversations about people, places, or situations, people often ask whether there is safety or whether a threat exists. So 'Sicherheit' describes the protected state, while 'Bedrohung' describes what endangers that state.

For the guests, the aggressive dog in the park was a real threat.
Nach dem Gespräch fühlte sie wieder mehr Sicherheit.
After the conversation, she felt a greater sense of safety again.
