Access control in the company: Requirements, data protection and practice for HR

Access control in the company | ZMI

Why access control is an HR issue today

Access control in companies is often still seen primarily as a security or IT issue. In reality, however, it is closely linked to HR processes, working hours, data protection and compliance. Medium-sized companies in particular face the challenge of managing access rights in an efficient, legally compliant and traceable manner – from onboarding to offboarding.

Digital access control systems do much more than just open doors. They support companies in combining security requirements with modern personnel processes and clearly mapping responsibilities.

What is access control in a company? 🔒

Access control refers to all organizational and technical measures that regulate who has access to buildings, rooms or company premises, when, where and under what conditions.

Typical areas of application

  • Company premises, parking lots/parking garages/underground garages and outdoor areas
  • Administration building and offices
  • Production and logistics areas
  • Server and technology rooms
  • Sensitive areas such as personnel files, research and development

Access control and HR: the most important points of contact

Onboarding and offboarding of employees 

HR is responsible for ensuring that new employees receive the correct access rights in good time and that employees who have left are blocked immediately. Manual processes with key handovers, lists or individual reconciliations are prone to errors and pose a security risk.  

Role and authorization-based access 

Modern access control systems enable differentiated access rights according to role, department or location. Temporary access, for example for temporary workers, service providers or external partners, can also be controlled in a targeted manner. This makes it much easier for HR to manage authorizations in a structured manner.

Link to working time and attendance

In many companies, access events, attendance times and working time recording overlap. It is important to note that access control does not replace time tracking, but can be usefully integrated – as long as the legal framework is complied with and the purposes are clearly delineated.


Access control and data protection: What is allowed? 

A key aspect of digital access solutions is data protection in accordance with the GDPR. Companies must ensure that personal data is only processed for a specific purpose, transparently and to an appropriate extent.

As a rule, the following are permitted

  • the storage of access events to ensure operation
  • logging for a limited period of time
  • access to data only by authorized persons

It becomes critical with

  • Permanent performance or behavior control
  • Changes to the purpose of the data, for example for secret working time evaluations
  • Lack of transparency towards employees

Transparent information, clear company agreements and defined deletion periods are therefore absolutely essential.


Access control and co-determination of the works council

As soon as access data is processed on a personal basis, the works council must generally also be involved. Companies should therefore determine the purpose of the system at an early stage, which data will be processed, who will have access and how a separation of access and performance data can be ensured.


Digital access control vs. manual access control in comparison ↔️

 
Criterion Manual (key) Digital
Administration Complex Centralized and automated
Security Rather low High
Traceability Hardly available Can be documented in an audit-proof manner
HR integration Not possible Very good
Scalability Limited High

👉 Digital access control is significantly more efficient and easier to manage in the long term, especially for growing companies.


Typical errors in practice

Many medium-sized companies make similar mistakes when introducing and using access control systems:

  • Access rights are not checked regularly
  • Former employees retain access to buildings or sensitive areas
  • There is no clear accountability between HR, IT and management
  • Data protection is only taken into account retrospectively

👉 These points not only pose security risks, but also organizational and liability-related problems.


Best practices for companies ✅

  • Define access rights based on roles
  • Standardize processes for entry and exit
  • Involving data protection and the works council at an early stage
  • Integrating access control with HR systems
  • Carry out regular checks of authorizations

Conclusion: Access control is part of modern HR compliance

Digital access control is no longer just a security issue. It is an important part of an integrated HR and compliance strategy for SMEs.  

Companies benefit from greater security, clear responsibilities, more efficient HR processes and better traceability in internal and external audits. 

Those who consider access control as part of their HR digitalization at an early stage create resilient processes and reduce risks at a central interface between personnel, organization and security.
