Threat levels

The VIGILNAT plan is at the heart of the national framework to protect against the terrorist threat. It was designed as a tool to identify the terrorist threat. The possibility of a terrorist attack is therefore constantly subject to evaluation.

The different threat levels laid out in the plan are:

Level 1 LOW

  • when the terrorist threat that is subject to analysis is judged to be possible, but improbable;

Level 2 MEDIUM

  • when the terrorist threat that is subject to analysis is judged to be real, but abstract;

Level 3 SERIOUS

  • when the terrorist threat that is subject to analysis is judged to be probable and concrete;

Level 4 VERY SERIOUS

  • when the terrorist threat that is subject to analysis is judged to be concrete and imminent, or if a terrorist attack has been committed.
