Sample Assessment Questions

Get a preview of the types of questions included in this assessment. Our comprehensive questionnaires help you identify gaps and strengthen your security posture.

1

Have you conducted a terrorist threat and vulnerability assessment for your building?

2

Do you maintain adequate standoff distance between the building and potential vehicle threats?

3

Have you implemented vehicle barriers (bollards, planters, walls) to prevent vehicle approach?

4

Do you have blast-resistant design features for high-risk building components?

5

Have you designed building envelope (walls, windows) to resist blast effects?

6

Do you have HVAC protection measures against chemical and biological agents?

7

Have you implemented progressive access control with screening at building entry?

8

Do you have structural redundancy to prevent progressive collapse?

9

Have you trained building personnel on suspicious activity recognition and reporting?

10

Do you have emergency response plans for terrorist attack scenarios?

Note: These are just a few examples. The complete assessment includes comprehensive questions across all control areas, with AI-powered guidance to help you implement improvements.
