Who can know the personal data processed by the KELER Group?

All KELER Group employees are bound by secrecy. The KELER Group places strong emphasis on ensuring with internal regulation and strict IT rights management that the data it controls and processes are known only to the employees to the job of whom the data concerned is related to, in the case of personal data, for example:

  • personal data of job applicants can be known to the HR Department and the colleagues and heads of the units posting the position,
  • data related to security purposes can be known to the colleagues of KELER Security Management and the Chief Security Officer,
  • data related to business development can be known to the colleagues and managers responsible for business development.

There are jobs at the KELER Group that promote compliance with regulations (Legal and Compliance, Internal Audit, Data Protection Officer). In order to perform work, the colleagues and managers of these units need to know the data processed or controlled by the KELER Group related to certain tasks.


To whom can the KELER Group forward personal data?

Data can be forwarded to meet the requirements of regulations, for example, in the following typical cases:

  • responding to requests by authorities or reporting to administrative or investigating authorities,
  • reporting suspected money laundering to the Finance Intelligence Unit of the National Tax and Customs Office (NAV),
  • in order to fulfil a contract, to the party involved (e.g. in the case of cross-border transactions or nominated ordering clients).

The KELER Group can forward to its partners performing outsourced activities the personal data related to the subject of the outsourcing. In certain cases, KELER and KELER CCP can forward personal data to the cooperating law firms*, for example in order to finalize a contract or related to a legal dispute. In this case, the law firm is required to manage the transferred data in line with the contract for legal services and the applicable regulations (in particular the secrecy stated in Act LXXVIII of 2017 on the Profession of Lawyer).

In other cases not regulated by law, when the need to transfer data to third parties arises, data is transferred subject to the written consent of the parties concerned, after prior information is given on the legal basis of data forwarding and the transferee. For example: filling a position at the KELER Group requires a test related to which KELER or KELER CCP wish to involve a third party service provider.

(*KELER Legal Department acts as the counsellor of KELER and KELER CCP.)


Security of data at the KELER Group

By law the systems of the KELER Group are considered system elements of vital national interest in the financial sector. Accordingly, the security environment is standard and operates in line with strict legal and regulatory requirements*, and is subject to ongoing and regular external and internal control and supervision.

(*E.g. Act L of 2013 on the Information Security of State and Local Municipality Organizations, Act CLXVI of 2012 on the Identification, Designation and Protection of Systems and Facilities of Vital Importance and related regulations, regulations of the financial sector and documents of the supervisors.)

Consequently, the KELER Group places great emphasis on the security of personal data it processes or controls, that is to say, to avoid violation of data security resulting in adventitious or unlawful destruction, loss, change, unauthorized communication of data or unauthorized access to data (data protection incident).

However, should a data protection incident nevertheless occur, the KELER Group has internal regulation that determines the method of incident investigation, involvement of the Data Protection Officer, informing the parties concerned and the National Data Protection and Information Security Authority (Authority), and the method of documenting and managing incidents without any delay.

Related to outsourced activities, the KELER Group cooperates with partners that guarantee the security of the personal data they come to possess. The provision of appropriate guarantees related to the security of data is a priority aspect when partners performing outsourced activities are selected.

The KELER Group manages physical documents containing personal data subject to strict security requirements. It is not possible to recover the destructed physical documents.

The KELER Group provides data protection training to employees to ensure data protection awareness, to facilitate the prevention and proper management of data protection incidents of IT or non-IT nature.
