Today, every modern business owner faces a unique security threat at every turn, and unauthorized access is the most common of all. It is considered one of the major risk factors for information compromise. And, the traditional ways once used to eliminate it, pose a greater threat due to various loopholes. Since keys can be stolen and/or copied, badges lost, they can create a security gap that can easily be taken advantage of. 

So, in this blog, we will go through common ways unauthorized access is gained at industrial sites. Let’s get started, shall we?


Tailgating is one of the most common ways to gain unauthorized access. It happens when an unauthorized individual follows the authorized personnel without providing their credentials through a door.


Known as a more intentional form of tailgating, the authorized personnel purposefully act to let the unauthorized individual who otherwise wouldn’t gain access through a secure door exposing the facility to risk.

Door Propping: 

Unlike collusion, door propping is often used by employees to gain quick access back to the building. This can lead to unauthorized individuals gaining access to the building and potentially risk everyone’s life and assets within.

Levering Doors: 

Common courtesy or user errors contribute to the possibility of unauthorized access, but so does a criminal’s ability to break in through the door. You’ll be surprised how easily doors can be levered using a small screwdriver. 

Lost, Stolen, Or Loaned Keys: 

Difficult to track when lost, keys can pose a major problem when an employee needs them to access the facility occasionally. Re-keying locks could prove expensive in such scenarios and also time-consuming when it is reported missing.

Access Cards: 

With the added advantage of identifying the authorized user, these cards act as a great alternative to traditional keys. Yet they are prone to similar risks of being lost, stolen, or shared, leading to unauthorized access to the building.

Industrial sites because of unauthorized access are subjected to physical theft of valuable devices and pieces of equipment, compromise of crucial information, vandalism, and even risk to human lives. The companies, therefore, must address existing loopholes to prevent possible threats, and one affordable way to do that is to contract security guard services from a reliable security guard company.
