Bulletproof is often used to describe something that is strong and resistant to damage or failure. For example, a bulletproof vest is a type of clothing worn by police or soldiers to protect them from bullets. It can also be used to describe software or technology that is highly secure and resistant to hacking or other cyber attacks. Outside of a literal sense, it can also be used metaphorically to describe a plan or strategy that is very effective and cannot be easily disrupted.
