by Roger WehbeSecurity breaches can cost Australian businesses far more than the initial investment in preventing unauthorised access. The impact can extend beyond stolen equipment or damaged property to include business disruption, lost productivity, reputational damage, regulatory obligations and compromised information.
For many organisations, this raises a practical question: is investing in access control systems more cost-effective than dealing with the consequences of a security incident?
In many cases, the answer is yes, particularly for workplaces and facilities where sensitive information, valuable equipment, critical infrastructure or large numbers of people are involved. The right access control strategy can reduce opportunities for unauthorised entry while giving organisations greater visibility over who is entering restricted areas.
This is increasingly relevant in Australia. The Australian Bureau of Statistics reported that 21% of Australian businesses experienced a cyber security incident during 2024–25. Businesses affected by incidents reported consequences including financial losses, downtime, lost productivity and reputational damage.
Physical security is only one part of a wider security strategy, but it remains an important layer of protection.
The Real Cost of Security Breaches for Australian Businesses
When people think about security breaches, they often picture stolen laptops, forced doors, or someone entering a restricted area. The financial impact can be much broader.
A breach may interrupt normal operations while staff investigate what happened. Access may need to be restricted, equipment replaced, and affected systems reviewed. If personal information is involved, an organisation may also have privacy and notification obligations.
The Office of the Australian Information Commissioner reported 1,205 data breach notifications during 2025, the highest annual number since Australia’s mandatory Notifiable Data Breaches scheme began in 2018. Malicious or criminal attacks accounted for 716 of those notifications.
Cyber incidents can also create significant financial pressure for Australian businesses. The Australian Signals Directorate reported that Australian businesses continued to experience substantial losses from cybercrime during 2024–25.
These figures do not mean every security breach will result in major financial losses. They do, however, demonstrate why organisations should consider security as a risk-management investment rather than simply another operating expense.
There is also a less obvious cost: uncertainty.
After an incident, management needs to determine how someone gained access, what they reached, how long they were inside, and whether the weakness still exists. Security systems that provide better control and visibility can make those questions easier to answer.
How Access Control Systems Can Reduce Security Risks
Access control systems are designed to regulate who can enter a building, zone or restricted area. Depending on the environment, this may involve cards, credentials, mobile devices, biometric authentication, turnstiles, speed gates or other controlled entrance technologies.
The important distinction is that modern access control is not simply about locking a door.
A well-designed system can establish different levels of access for employees, contractors, visitors and other authorised users. Someone working in an administration area, for example, may not need access to a server room, secure archive or high-value storage area.
This principle of limiting access to what a person actually needs is also reflected in Australian Government cyber security guidance. Cyber.gov.au recommends using access controls to limit the files, accounts and systems a staff member can access, reducing potential damage if an account or device is compromised.
Physical access works in a similar way.
Rather than treating an entire building as equally accessible, organisations can create controlled zones. This can be particularly useful for data centres, healthcare facilities, government buildings, transport infrastructure, warehouses and corporate offices.
Businesses exploring different approaches can review access control solutions to understand how controlled entry can form part of a broader security strategy.
What Should Businesses Consider When Choosing Access Control?
There is no single access control solution that suits every Australian organisation. The right system depends on the building, number of entry points, security requirements, traffic levels and existing infrastructure.
Installation complexity, authentication technology, integration with other security systems and ongoing maintenance can also influence the overall investment.
This is why businesses should avoid comparing access control purely on its initial installation cost.
A better question is:
What level of risk are you trying to reduce, and what could happen if that risk becomes an actual security incident?
For a small office with limited access requirements, a straightforward solution may be appropriate. A data centre, transport facility or critical infrastructure site may require several layers of security and more advanced entrance control.
The wider range of entrance control products demonstrates how different technologies can be used for different environments and security requirements.
Businesses should also consider the system’s long-term reliability and ability to integrate with existing or future security infrastructure. A solution that cannot adapt as the organisation grows may become less effective over time.
Security Breaches Can Affect More Than Your Balance Sheet
Financial loss is an obvious consequence of a security incident, but it is rarely the only one.
Consider a business where an unauthorised person gains access to a restricted staff area. Even if nothing is stolen, employees may lose confidence in the workplace. Management may need to investigate the incident, review procedures and explain what happened.
In a healthcare environment, the stakes can be considerably higher. Sensitive areas may contain medicines, patient information, specialist equipment and restricted clinical spaces.
In education, access control can help separate public areas from staff-only and student-only zones. In transport and critical infrastructure, controlled movement can form part of a wider operational and security strategy.
Australian Government guidance on physical security recommends defence-in-depth, where multiple security layers work together to protect facilities, systems and people.
This is an important point: access control should not be viewed as a standalone solution to every security problem.
It is one layer within a broader security framework.
When Investing in Access Control Makes the Most Sense
The business case for access control becomes stronger when the consequences of unauthorised entry are high.
For example, a data centre may need to protect critical infrastructure and restrict access to highly sensitive areas. A financial organisation may need controlled movement between public, employee and secure zones. A warehouse may need to protect valuable stock while managing staff and contractor access.
High-traffic buildings have another challenge: security cannot come at the expense of efficient movement.
Traditional security measures can create queues or encourage people to bypass controls when they become inconvenient. Modern entrance control systems can be designed to manage pedestrian flow while maintaining controlled access.
This is particularly relevant in offices, stadiums, transport hubs, education facilities and other environments where large numbers of people need to move through entrances quickly.
Gunnebo Entrance Control Australia provides entrance control solutions for a range of Australian environments, including commercial buildings, critical infrastructure, transport, education, leisure and healthcare.
The objective is not simply to make entry more difficult. It is to make authorised access straightforward while making unauthorised access significantly harder.
The Honest Limitation: Access Control Cannot Prevent Every Breach
It is important to be realistic about what access control systems can achieve.
Installing a sophisticated entrance system does not make an organisation immune to security breaches. An authorised employee could lose a credential, allow someone to follow them through an entrance or deliberately provide access to another person.
Cyber attacks can also occur without anyone physically entering a building.
The OAIC continues to identify malicious or criminal attacks as a major source of reported data breaches, demonstrating why organisations need more than physical security alone.
This is why physical access control should sit alongside cybersecurity, staff training, identity management, surveillance, visitor management and appropriate operational procedures.
There is also a risk of over-specifying a system. Installing technology that is unnecessarily complex for a low-risk site can create avoidable expenses, while choosing an inadequate solution for a high-risk facility can leave important vulnerabilities.
The right approach is to match the level of protection to the actual risk.
How to Assess the Value of Access Control
Businesses can make the decision more objectively by looking beyond the initial investment.
Start by identifying what could realistically be affected by unauthorised entry. This might include equipment, stock, confidential information, intellectual property, personal information or critical operational systems.
Then consider the operational consequences. How much disruption could an incident cause? Would employees be unable to access important areas? Could customers or suppliers be affected? Could the organisation face regulatory or contractual consequences?
Finally, consider the likelihood of the threat.
A facility with valuable assets, numerous entry points, high staff turnover or large visitor numbers may have a very different risk profile from a small office with limited physical access.
The assessment can be viewed simply:
Potential breach impact = direct loss + downtime + investigation + recovery + reputational impact + regulatory or legal consequences.
Security investment = equipment + installation + integration + maintenance + future upgrades.
Neither figure can be predicted perfectly. However, comparing the potential impact of an incident with the investment required to reduce the risk can help decision-makers make a more informed choice.

Why Prevention Is Usually Better Than Recovery
The strongest argument for access control is not that it guarantees prevention. It is that it can reduce exposure before an incident occurs.
Once a breach has happened, the organisation is responding rather than choosing.
That may mean investigating the incident, repairing damage, replacing equipment, dealing with affected customers or employees and restoring normal operations. The business may also need to review why existing security measures failed.
By contrast, a properly planned access control system provides a proactive layer of protection that can be managed, maintained and improved over time.
For Australian organisations, the decision should therefore be based on risk rather than fear: what needs protection, who should have access, where are the vulnerabilities, and what would a successful breach mean for the organisation?
The answer will vary from one facility to another, but for many organisations, strengthening physical access is a practical way to reduce the potential impact of security incidents.
Ultimately, effective security is not about making every entrance difficult to use; it is about making authorised movement easy while making unauthorised access significantly harder.
