Unannounced data protection audits: How companies can best prepare
A surprise at the door: What do spontaneous checks mean?
Most of us have experienced it: sudden tests or checks often trigger a feeling of uncertainty. This applies not only to school exams, but also to unexpected checks by authorities – whether in road traffic or on public transport. It becomes particularly unpleasant when inspectors from the data protection supervisory authority suddenly show up at the door of companies or public institutions.
This situation is likely to become more common in the future: data protection supervisory authorities are increasingly using unannounced on-site checks to verify compliance with data protection regulations. The aim is to identify weaknesses in internal processes directly on site, eliminate deficiencies and minimise the risk of data protection violations. During such visits, they not only check who has access to sensitive areas, but also whether data protection concepts, procedure directories and order processing agreements are in place and up to date. Both managers and employees may be questioned. These checks are no longer limited to public bodies, but can affect any company.
Why are these checks legally possible in the first place?
Legally, data protection authorities are authorised to carry out comprehensive audits under the General Data Protection Regulation (GDPR) and supplementary national provisions. Not only are they allowed to inspect all necessary documents, but they also require access to a company's premises, IT systems and data processing equipment in the course of their duties.
However, the authorities must always observe the principle of proportionality – this means that an inspection should have a legitimate reason, should not unduly disrupt business operations and should preferably take place during regular working hours.
Depending on the federal state, special provisions apply to public institutions governing access to service and business premises. In some cases, fundamental rights – such as the protection of the home – are even partially restricted if there is a risk of serious data protection violations. Overall, however, the regulations leave little room for manoeuvre: those responsible must expect checks and make the necessary preparations.
How to successfully handle on-site inspections: tips and measures
Important for companies: verify identities and clarify procedures
If your company or public authority is targeted by an unannounced inspection, it is advisable to act quickly and deliberately. First, you should consistently check at reception whether the visitors are actually employees of the supervisory authority – ask for official identification. This will help you avoid falling for social engineering, as criminals often use similar tactics to gain access and steal data.
Next, you should ask for a clear explanation of the scope of the inspection: Which areas or documents are affected? Does it concern specific projects, IT systems or general processes? This allows you to inform the most important contact persons and avoid bottlenecks in your operations as far as possible. If an inspection cannot be accompanied or answered because no employees who can provide information are present, this should also be documented and explained to the authority.
Documentation and training: your key to successful control
A fundamental part of preparing for unannounced audits is the structured and centralised documentation of all data protection-related documents, concepts and processes. More sensitive areas – such as server rooms, personnel file management or monitoring systems – should also be continuously checked for data protection compliance.
An internal data protection officer – such as a data protection coordinator or data protection officer – should always be available to provide information to the authorities and accompany the inspection. If possible, establish a written internal process that sets out clear steps for inspections: from identity verification and notification of management to documentation of the entire process and the inspection results.
It is also advisable to regularly raise awareness among employees and familiarise them with the procedures in the event of an inspection. This will avoid uncertainty and ensure a swift, professional response.
Conclusion: Preparation is everything – and pays off in an emergency
See unannounced audits as an opportunity
Even though spontaneous visits by data protection authorities can initially cause stress, they offer a valuable opportunity to review your own structures and processes. Companies and authorities that regularly work on their data protection organisation and establish clear responsibilities see such audits less as a threat and more as an opportunity for optimisation.
However, it is essential to check the identity of the inspectors, keep documents readily available and ensure that trained contact persons are available. An open, cooperative attitude towards the supervisory authority helps to identify any weaknesses and find quick solutions together – in the interests of protecting personal data, but also to minimise risks and damage.
