Since the introduction of the GDPR, organisations are legally obliged to handle personal data with care. Many companies focus on data processing agreements, technical security, and privacy policies. However, a large share of data breaches comes from something seemingly simpler: incorrect or poorly managed access control.

Who has access to personal data ultimately determines whether privacy is protected or not. And that makes IAM a crucial pillar under GDPR compliance. It not only protects data but also shields the organisation from fines, reputational damage, and unnecessary risks.

Access control is a topic that many organisations underestimate. As long as systems are working, it doesn't seem a priority. Until an audit comes, a data breach is reported, or an employee accidentally accesses information they should not be able to see.

IAM ensures that the organisation enforces data privacy not through Excel lists or ad-hoc actions, but via a logical, policy-driven, and automated process. Exactly what the GDPR demands.

Why access control is central to the GDPR

The GDPR outlines numerous principles, but three of them directly relate to IAM: data minimisation, authorisation, and accountability.

Data minimisation

Organisations may only process personal data when it is necessary. This also applies to access. An employee may not have more rights than necessary to perform their role. In practice, rights often increase due to turnover, temporary projects, or manual decisions. This leads to over-access, which increases risks.

Authorisation

The GDPR requires organisations to take appropriate technical and organisational measures to limit access. If accounts are not promptly closed or external parties retain extensive rights, an organisation does not meet this obligation.

Accountability

Organisations must be able to demonstrate compliance with the law. Not just in theory, but with evidence. This means every access decision, change, and closure must be reproducible.

Without IAM, it is almost impossible to meet these requirements without huge administrative burdens.

The reality: where things often go wrong

Many data breaches are not caused by hackers but by human errors or outdated processes. Consider:

• employees retaining access after a job change

• external parties still active after a project is completed

• accounts that remain because offboarding is not uniform

• SaaS applications where rights are manually maintained

• shared accounts where no one knows exactly who is using them

These situations pose direct GDPR risks because personal data is not protected according to the principles of necessity and proportionality.

In addition, organisations are increasingly using cloud applications, causing data to be spread across multiple systems. As long as there is no central IAM process, it becomes unclear where data is accessible and to whom.

How IAM strengthens data privacy

IAM ensures that access to personal data does not depend on good intentions, but on clear rules and automatic processes. Joinly plays a key role in this by synchronising identities from the HR system and determining access according to RBAC and ABAC.

One source of identity

HR registers employees as usual. Joinly automatically retrieves this data and creates a correct identity foundation. No more separate administrations, no unknown accounts.

Access determined by policy

In Joinly, access is not granted by individual decisions but by RBAC and ABAC:

• RBAC determines access per role, such as HR employee or manager

• ABAC determines access based on attributes, such as location, contract type, or team

This structurally prevents employees from gaining access to more data than necessary.

Automatic provisioning and deprovisioning

Once someone starts, changes roles or leaves, Joinly processes this automatically. Rights are assigned or withdrawn at the right time. This eliminates the greatest GDPR risks because accounts do not linger.

Complete traceability

Every access decision is automatically logged and reproducible. In the event of a data breach, the organisation can immediately show who had access, when access was granted, and why it was so.

Management of external access

External parties pose a significant privacy risk. Joinly manages external identities the same way as internal employees, including automatic deprovisioning.

IAM makes GDPR compliance not theoretical but demonstrable.

Joinly as a foundation for privacy-friendly access control

Joinly is designed for organisations that depend on many cloud applications, external parties, and dynamic teams. The platform makes access control logical, scalable, and reliable.

With Joinly, the GDPR does not become a recurring challenge but a structurally secured process where:

• access can be predicted

• data minimisation is automatically enforced

• external parties are managed securely

• accounts never remain unnecessarily

• audits run smoothly

• evidence is one click away

Thus, IAM not only makes systems safer but also organisations future-proof.

Protecting data starts with the right access

GDPR compliance is not a one-time effort. It is an ongoing process in which access control plays a central role. Organisations that take IAM seriously not only protect personal data but strengthen their entire operation.

Joinly provides the technology needed to do this in a controlled and explainable manner.
