The Most Common Business Security Mistakes and How to Avoid Them

When it comes to owning or operating a business, the main focus point is usually making profits. While that is an integral part of running a successful business, other areas need just as much attention, such as business security.

When focusing on growth, business security often gets neglected. If you think about it, this is the biggest mistake that businesses can make. Business growth and security go hand in hand. A slip in security could make your business vulnerable to criminals and hamper growth and profit-making.

Every business needs a way to keep its people, property, and assets safe from criminals and protect itself from any form of loss. Luckily, there are several ways you can do so, all the while focusing the major chunk of your time on growth and productivity.

Read on to find out about the most common business security mistakes and ways you can avoid them to make yourself and your business safe and secure:


Let’s start with the basics. The biggest mistake that businesses can make is to not give security its due importance. Sadly, the majority of businesses start to even think about business security only after an incident has taken place. By then, the damage is usually done and it is oftentimes too late to bounce back for some.

As a business owner, you simply cannot ignore the need and importance of business security because, in the majority of cases, the damage could have easily been avoided by taking a few simple steps and security precautions.

According to recent statistics, around 469,000 businesses experienced crime in the past year in the UK. This included all kinds of businesses, from wholesale and retail to transport, food, accommodation, manufacturing, and construction. Some of the most common crimes committed include commercial burglary, vandalism, vehicle theft, robbery, assault, and fraud.

All these statistics and key figures highlight the importance of not only protecting your business from external threats but also internal ones.

How to avoid this?

To avoid this mistake, you need to first understand the importance of business security yourself and then instil it as part of the work culture.

Everyone in the business, including the owners, managers, employers, employees, and visitors needs to play their part in ensuring a safe and healthy environment that is protected from all kinds of security threats.


Many businesses understand the importance of security but one of the biggest mistakes on their part is failure to develop a proper security plan and implement it strategically.

Everything, including business security, requires proper planning. You need to assess your security requirements and clearly outline the goals to achieve. This will not only give a clear direction but also make your security measures all the more effective.

A detailed plan will include everything from highlighting all the risks and determining the best ways to mitigate those risks. The best way to make a detailed plan is to conduct a security risk assessment.

How to avoid this?

A security risk assessment is a process that enables business owners to assess and evaluate their current security measures and get a better understanding of the security risks that lie ahead.

The main role of this assessment is to determine how well the current security measures are at mitigating the risks and keeping everyone and everything safe and secure.

It consists of a variety of different criteria which include what the risks are, where they are taking place, the chances of the risks manifesting, the measures in place to mitigate them, whether they are a priority, and whether the risk has been fixed.

It may be helpful to seek the assistance of a professional security company when creating a security plan for your business. They may either help you with the security risk assessment or conduct it themselves. As a result, you will have a customised business security plan that is made for your unique security needs.


When it comes to security threats, the most common ones that come to mind are usually the ones that come externally. They include burglaries, intrusions, vandalism, and more.

What most businesses fail to recognise is the risk of internal threats, which are a very real and serious matter to consider. Internal threats are those that businesses face from employees, former employees, business associates, or contractors.

They come from someone from within the business who can exploit important data and resources and cause the business all sorts of damage. Some of the most common types of internal threats include unauthorised employee access, accidental disclosure of data, social engineering, physical theft, and vandalism.

Internal threats can oftentimes be much more dangerous and damaging than external threats because they are unexpected for many businesses and come from someone that they thought they could trust.

How to avoid this?

To avoid this issue, it is very important to give as much importance to internal threats as you give to external threats. Both can be damaging to your business and need to be eliminated as much as possible.

A simple solution for this is to have a proper pre-employment screening process that thoroughly vets new employees, including conducting criminal background checks on everyone.

In addition to that, make sure you have all the required information on the individual before making them a part of your team. It is also very important to have proper security checks such as implementing a proper access control system, limiting the number of keys you hand out to the employees, and using monitoring systems in high-risk areas.


Failing to secure access points, which include all the entrances to your business must be secured against unauthorised access. If your business has more than one access point, every single one must be secured.

Sadly, to save a bit of money, what many businesses do is that they secure the main entry points while neglecting the rest. This is a grave mistake that could severely cost them in the long run.

Opportunist criminals are on the lookout for a slip-up on your part and your inability to secure every access point, including the doors, windows, and emergency exits, gives them the perfect chance to carry out their malicious plans.

Some areas of your business might be more at risk than others, and you must determine which areas need an extra layer of security. Certain rooms within the premises may hold valuable assets or information and will need extra attention on your part.

How to avoid this?

To avoid this issue of unauthorised access to your business premises, you need to focus on more than just the front door. Be sure to lock all the doors and windows to restrict access and provide comprehensive security to keep people and property safe.

You may want to seal off access to certain areas of the business, and for that, the most effective form of security is to install an access control system. This will not only grant access to specific employees but also give you much more control over who gained access to which area of the business and when.

You may control access within your business premises by using various types of access control systems such as key codes, key cards, fobs, and biometric access control.

To make the system even more effective, you may install alarms, put the access points under constant surveillance of CCTV cameras, and even station physical guards to deter threats at each entry point.


Installing CCTV cameras on business premises is an important and effective security measure to prevent theft, vandalism, unauthorised access, and other types of security threats. Coupled with professional CCTV monitoring services, it gives businesses much more control and peace of mind and allows them to focus on growth and productivity instead of worrying about security threats.

The issue arises when businesses do not give importance to the placement of CCTV cameras and are unable to determine the most efficient places to position them. This includes figuring out the right place and also the best height and angles for optimal viewing.

If the CCTV cameras are not placed in strategic locations, they will fail to provide protection and won’t work as effectively as they should. To get the best use out of them, strategic positioning is key.

How to avoid this?

The best way to avoid the wrong placement of CCTV cameras is to discuss the right angles and positions with a professional security company that can guide you best regarding the full use and potential of the surveillance system.

The installers need to consider all the crucial access points as well as those areas that are high-risk, for instance, the locker rooms, vaults, and server rooms. The best height and angles need to be used, and all blind spots need to be avoided to make your CCTV camera a worthy investment.

When installing CCTV cameras at the entrances and exits, it is important to place them in strategic, visible spots so that visitors are always aware that they are being monitored. A visible CCTV camera acts as an effective deterrent against thieves, vandals, burglars, and trespassers since they fear getting recorded and caught.

It is also important to consider proper lighting when installing CCTV cameras so that the resultant footage is clear. Adequate lighting is key, but also make sure to avoid direct light sources as they may produce blurred footage. Infrared and night vision cameras are a good option when looking to monitor dark areas with minimal lighting or for night-time surveillance.


One of the biggest mistakes that business owners make is that they have state-of-the-art security systems installed on their premises and then completely forget about them. While it is true that modern systems work mostly on auto-pilot and require minimum human input, the systems do require regular maintenance.

Proper and regular maintenance of security systems such as intruder alarms, CCTV cameras, and access control systems is just as important as installing the right systems. The inability to have them properly maintained leads to malfunctioning or system failure, both of which can put the business and everyone and everything in it at risk.

Some of the most common faults that these systems can develop include faulty sensors, battery issues, loose cables and connections, and faulty control panels or keypads. Out-of-date security systems such as CCTV cameras can also be targeted for hacking to access sensitive data.

How to avoid this?

The best way to avoid these issues from arising is to have the security systems regularly maintained and serviced. To avoid faults from developing, make sure to check the systems periodically so that they stay in good working order.

If the security systems are not working properly, they are just a waste of money and can leave you and your business unprotected.

Make sure you protect your security systems from extreme heat and moisture that may cause them to rust and get damaged. In addition to that, objects that might act as obstructions to the sensors must be kept away such as moving objects, fans, and curtains.

You should make it mandatory to gently sweep the security systems and check their angle and positioning to make sure they work properly. For a thorough check-up though, it is recommended to call a professional so that the system can be cleaned inside out and any potential faults can be fixed before they become an issue.

Some security companies like Calder Security also offer maintenance contracts for businesses that ensure the system will be looked after and all its servicing needs will be taken care of, leaving you, the owner and user, carefree and at ease.

To prevent CCTV cameras and other security systems from being hacked, make sure you keep their software updated at all times and avoid installing cheap knock-offs that are available easily everywhere.

Do your research and ask your security company for suggestions. Without a properly maintained and up-to-date security system, you will be leaving your business vulnerable to theft, break-ins, and other kinds of threats.


Integration of security systems is a key factor in security. Sadly, it is one that most businesses tend to overlook. Although standalone security systems are effective as well, when integrated, they pack quite a punch.

For instance, maybe you have CCTV cameras installed on your property, but some areas within the business get little to no coverage. Or maybe you have alarm systems installed in all the key areas but there is no way to monitor your property.

This leaves loopholes in the security measures, which is something that criminals are always on the lookout for. Such circumstances are just what they need to carry out their illegal acts without getting caught.

How to avoid this?

The best way to avoid this is to diversify your security measures and use overlapping systems to provide more comprehensive security coverage.

Integrating different security systems is a great way to increase security at your business and deter intruders and other criminals from targeting your property and assets.

It is very important to integrate all of your security systems such as the cameras, alarm systems, and access control so that you can use all the systems’ unique features in case of a threat. You may even consider supplementing your security systems with security guards for on-the-ground surveillance and quick response.
