Bullet Proof + Bullet Resistant

What is the difference?

Bullet Proof
Capable of absorbing the impact of a bullet without any error or shortcoming.


Bullet Resistant
Able to sustain attack to the resistance level specified against a targeted attack.


And what do they mean?

An effective security strategy starts with understanding a key distinction in the different types of terminology you might see online. For most people, the term ‘proofing’ is the accepted specification to be asking and searching for. However, ‘proof’ and especially ‘bulletproof’ implies a level of resistance that is difficult to obtain – as it is a guarantee of protection against ballistic attack. This is impossible as the threat and methodology of crime is always evolving and what is deemed as ‘Bulletproof’ today may not be in the future. Security solutions and resistance from times past do not necessarily hold up as crime and the terror threat continues to become more sophisticated in their attempt to cause unrest and damage.

Security decision-makers often rely on a ‘Deter’ and ‘Delay’ scheme to understand the physical security defence process. Security solutions are designed to deter criminals, delay attacks from causing severe damage, protect staff and assets, and survive until a fully equipped Response Team can arrive on the scene. For this reason, physical security is often built around the idea of delaying major damage, as it is often impossible to prevent completely. With enough explosives, bullet, time and man-power forced against a product, all protection can and will eventually fail.

For this reason, a trained security professional should never label anything as ‘proof’ and instead should use ‘resistant.’ ‘Resistant’ has become term used more frequently by specifiers as it highlights the strength of good security measures, without overstating them.

Bullet Resistance

Bullet Resistance is defined by firearms, including the use of pistols, assault rifles and shotguns. The protection is rated using the European (EN) Standards, which specify the weapons and types of prolonged damage.

Blast Resistance

Blast Resistant tests are frequently conducted and rated by assessing resilience to the use of heavy TNT explosions.
