Perimeter Security

The perimeter of your office or building is a property line or boundary that distinguishes what’s yours and what’s not. It is often the first line of defence against criminal activity. After all, an unsophisticated intruder who is seeking to enter your business secretly will initially cross the perimeter. But a perimeter can take many forms, from a wall or boundary to a security fence or even just a change of landscaping. So, what’s the best way to protect your business and what perimeter or barriers should you use?

In most cases, a perimeter is designed to form a barrier or channel legitimate users through a controlled entry point. They can be man-made, such as a fence or gate, or they can be natural such as a cliff or river. A perimeter of any kind will not deny access to a determined intruder, however, when defining a perimeter, it should:

  1. Protect employees from hostile actions.
  2. Reduce the number of entry/ exit points.
  3. Delay intruders so that the threat can be assessed.
  4. Channel intruders into pre-planned safe zones.
  5. Allow for the effective use of security guards.

Having looked at what a perimeter should do, it is also worth looking at ways a perimeter can be compromised. This will ensure that your perimeter is up to the task.

  • Accidentally. A person or persons inadvertently trespass onto private land.
  • Force. The perimeter barrier is forced apart to allow entry.
  • Stealth. The perimeter barrier is overcome without leaving evidence of entry.
  • Deceit. Guards or receptionists are tricked into allowing entry.

So, what’s the best way to protect your business and what perimeter or barrier should you use? We have put together some guidance and advice to consider:

  1. A properly designed perimeter should be clearly obvious, where it starts and ends and where the correct points of entry/ egress are. It should clearly warn a potential intruder to “keep out”.
  2. Consider the threats against your business. Is it single intruder breaking in through a door or window? Or could it be a “gross attack” on your external walls or shutters? The nature of your perimeter will greatly depend on those threats.
  3. Consider using a layered perimeter. If a perimeter is being penetrated by stealth, an intruder will attempt to go around or through it without being detected. Supplementary countermeasures, such as CCTV and alarm sensors should be integrated to ensure the integrity of the perimeter.
  4. Think, “do all my staff know their role in protecting the business?” Ensure all members of your staff, particularly guards and receptionists, are fully trained and aware of their roles.

The right perimeter for your business will greatly reduce criminal activity and getting it right the first time will greatly reduce the amount of money you need to spend on it. If you would like to know more about protecting your business, or you have any questions, then please get in touch.
