The shortage of skilled workers is forcing authorities and municipal institutions to take action: recruiting processes must be made more efficient, more digital and more attractive. At the same time, the requirements for proof of IT security, data protection and compliance are increasing – both internally and to external auditing bodies.
At the latest when IT, data protection or the staff council are involved, a software decision becomes a fundamental question: How secure is the system used?
Recruiting is no longer an isolated process. Job advertisements, applicant data and coordination processes are displayed in cloud-based systems. This is exactly where it is decided whether a solution is not only functionally convincing, but can also be operated responsibly and in accordance with the rules.
ISO 27001: An established foundation
ISO/IEC 27001 is a central reference point in many selection processes.
It proves that a provider organizes information security in a structured manner – with clearly defined responsibilities, risk management and verifiable processes.
This represents an important basis for HR managers. However, in practice it often becomes clear that it is necessary, but not always sufficient, proof.
The crucial question remains: How are security requirements actually implemented during ongoing operations?
A look into practice
This is where the distinction becomes relevant. There is often a gap between the definition of processes and their actual application in everyday life, which is only partially visible in classic provider presentations. This is where the C5 criteria catalog from the Federal Office for Information Security comes in. It was developed specifically for cloud services and creates transparency about security-relevant processes in operations, for example in the areas of:
- Access and authorization management
- Change and configuration processes
- Logging and traceability
- Dealing with security incidents
C5 thus supplements existing safety evidence with a more operational perspective.
What does this mean specifically for HR?

For HR managers, the focus is less on the technical depth of detail than on the quality of the basis for decision-making. A C5 report can help:
- Evaluate providers in a more structured manner
- To facilitate coordination with IT, data protection and co-determination
- Identify risks early on
- To make selection processes more comprehensible
What remains important is that a C5 attestation supports the assessment, but does not replace an organization-specific examination.
Conclusion: Security is a prerequisite
Cloud security is no longer an optional addition, but a fundamental requirement for successful digitalization in recruiting. When selecting systems, not only functionality and user-friendliness, but also certificates and attestations should be systematically taken into account.


- ISO 27001 shows that information security is organized in a structured manner
- C5 creates transparency about implementation in cloud operations
Particularly in the German market, a C5 Type 2 attestation is considered meaningful proof of cloud security and a relevant component for reconciling innovation and compliance.
