Billy Hopkins, Country Manager UK at Synguard explores how rising cyber-threats and evolving regulations are reshaping access control infrastructure.
For many years, the debate around cloud versus on-premise access control was largely theoretical.
Security professionals discussed the advantages and drawbacks of each model, often guided by long-standing assumptions about where critical systems should reside.
In particular, the belief that local infrastructure automatically provides stronger protection has remained common across many organisations.
Today, however, the conversation is changing.
Cyber-threats are increasing, regulatory expectations are evolving and organisations are reassessing how their security infrastructure is designed and managed.
In this environment, the architecture of access control systems is no longer simply an IT preference. It has become a strategic decision about resilience, responsibility and operational continuity.
Recent research highlights the scale of the challenge.
According to Cloudflare’s Europe’s Cyber Threat Landscape 2024 report, 72% of European organisations experienced at least one cyber-incident within the past 24 months.
Among those affected, 63% reported financial losses of at least €940,000.
At the same time, only 29% believe they are well prepared for future cyber-incidents.
These figures underline an important point.
Cyber-risk is now an operational reality rather than a theoretical possibility.
As organisations review their exposure to these risks, the way critical systems such as access control are deployed is increasingly coming under scrutiny.
Traditionally, access control software has often been hosted on servers located within an organisation’s own IT infrastructure.
For many companies, this model offers a sense of direct control.
Systems remain within the corporate network, internal teams manage the infrastructure and the organisation retains ownership of the hardware and software environment.
However, the operational responsibilities that come with this model can be significant.
Local hosting requires organisations to maintain servers, manage patch updates, perform backups and ensure that hardware remains secure and operational.
Power redundancy, cooling systems, fire protection and disaster recovery planning also become internal responsibilities.
These tasks are often handled effectively by capable IT departments.
Yet they still require ongoing resources, attention and expertise.
As infrastructure ages, hardware must be replaced, systems must be upgraded and security patches must be applied promptly to prevent vulnerabilities.
Another factor to consider is the relationship between access control systems and the broader corporate network.
When security applications are hosted within the same environment as other business systems, a successful network breach can potentially affect multiple services at once.
In such scenarios, physical access management may become exposed to the same risks that affect other network-connected applications.
Cloud-based access control introduces a different operational structure.
Instead of relying on locally maintained servers, the software runs within professionally managed data centre environments designed for continuous availability and high levels of security.
In these environments, infrastructure is monitored around the clock and designed with redundancy in mind.
Multiple systems can operate in parallel so that if one component fails, another takes over without interrupting service.
Backups, software updates and monitoring processes are typically integrated into the platform itself.
This approach shifts part of the operational responsibility away from the customer’s internal IT team and towards specialised providers whose primary focus is maintaining secure and resilient infrastructure.
Cloud environments also tend to operate under formal security frameworks such as ISO 27001.
These frameworks require structured processes for risk management, incident response, access management and ongoing monitoring.
For organisations facing increasing regulatory scrutiny around cybersecurity governance, such frameworks can provide additional reassurance that security practices are being maintained consistently.
Access control systems occupy a unique position within organisational infrastructure.
Unlike many other applications, they are directly tied to the physical functioning of a building.
If they become unavailable, the consequences are immediate: Staff may be unable to enter facilities, operations can be disrupted and security procedures may be compromised.
For this reason, operational continuity is a central consideration when evaluating deployment models.
Modern cloud architectures are designed to minimise downtime through redundancy and geographic separation.
Data centres typically include multiple power supplies, network routes and failover systems to maintain service availability.
In many cases, systems are distributed across separate locations so that a disruption in one facility does not interrupt the overall service.
For organisations attempting to replicate similar levels of redundancy within their own infrastructure, the cost and complexity can be considerable.
Another aspect influencing the cloud discussion is the management of sensitive information.
Access control systems process personal data relating to employees, visitors and contractors.
As privacy regulations such as the General Data Protection Regulation (GDPR) continue to shape data governance practices, organisations must ensure that this information is handled securely and responsibly.
Professionally managed cloud environments often incorporate features designed to address these requirements.
These may include encrypted communication, controlled data access, automatic backups and defined data residency within specific geographic regions.
Such capabilities can help organisations demonstrate compliance with evolving data protection expectations, particularly when systems are independently audited under recognised security standards.
While cloud adoption is growing, no single deployment model suits every organisation.
Some continue to favour on-premise systems due to internal policies, legacy infrastructure or specific operational needs, while others are moving to the cloud to simplify management and improve resilience.
As access control platforms are long-term investments, flexibility is increasingly important.
Over time, organisational priorities, regulatory requirements and technology strategies can all change.
Platforms that support both cloud and on-premise deployment within the same environment offer valuable adaptability. Users benefit from a consistent interface, while administrators manage the same functions and workflows regardless of where the system is hosted.
This consistency makes it easier to move between deployment models if circumstances change.
For example, an organisation may start with an on-premise system and later transition to the cloud – or vice versa – without extensive retraining or complex reconfiguration.
The cloud versus on-premise access control debate reflects a broader shift in security technology.
Modern platforms are increasingly integrated with systems such as identity management, building management and mobile credentials, often extending beyond a single network.
Cloud platforms support this by enabling secure, encrypted communication across environments, reducing complexity while connecting systems to wider digital ecosystems.
Ultimately, the cloud versus on-premise debate is shifting from a binary choice to a focus on resilience, security and flexibility.
What matters most is the ability to deploy and manage access control in a way that suits each organisation’s needs, with the freedom to move between environments as required.
