How a data protection audit works

What is a data protection audit?

A data protection audit is a voluntary, systematic review of a company's level of data protection. It evaluates how GDPR requirements are implemented in documentation and operational processes. Depending on the scope, the audit can cover the entire company or specific business units.

Clarity regarding your data protection status

When is a data protection audit useful?

A data protection audit helps companies systematically assess their current data protection status and identify potential gaps in GDPR compliance. Typical reasons for a GDPR audit include:

  • A data protection audit conducted some time ago
  • Reviewing existing data protection processes
  • Targeted auditing of specific business units or projects
  • Preparation for certification
  • A general assessment of your current data protection level

Key areas of focus

What is assessed during a GDPR audit?

Depending on the scope of the audit, we set different priorities. Key audit objects include, among others, the following documentation and processes.

01
Record of Processing Activities
The ROPA maps out which processes involve the processing of personal data. During the data protection audit, existing information is cross-referenced with GDPR requirements.
02
Technical and Organizational Measures
TOMs describe how personal data is protected both organizationally and technically. The GDPR audit verifies whether these measures are documented and implemented within the company.
03
Data Processing and DPA Contracts
The documents reviewed also include completed data processing agreements with external service providers. This involves verifying whether existing DPA contracts meet GDPR requirements.
04
Deletion, Role, and Access Concepts
This covers how long data is retained and when it is deleted. It also examines who is authorized to access specific data and how these permissions are managed.
05
Data Protection Impact Assessment
The DPIA process is one of the potential subjects of a GDPR audit. It concerns processing activities that are likely to result in a high risk to the rights and freedoms of natural persons.
06
Handling data protection incidents
The data protection audit also examines existing procedures for data breaches. This involves reviewing which external and internal processes are in place for such incidents.

How Proliance supports your data protection audit

We align the focus of the GDPR audit with your specific situation and the agreed scope of the assessment. The implementation follows a clearly structured process.

Structured inventory

We use a questionnaire to record the current status in your company, taking into account existing measures, documentation, and relevant processes.

Professional assessment by data protection experts

Our experienced data protection experts compare the recorded status quo with the requirements of the GDPR. In doing so, they identify and assess vulnerabilities and risks.

Individual audit report

The report documents the established status quo and measures already implemented. This ensures that the results of the GDPR audit are consolidated and easy to follow.

Concrete recommendations for action

We derive concrete recommendations for action from the results and prioritize the measures accordingly. This provides you with clear guidance for your next steps.

Frequently asked questions

Frequently asked questions about data protection audits

What documents are required for a data protection audit?

The documents required for a GDPR audit depend on the specific audit framework. Typical documentation includes the record of processing activities, internal data protection policies, signed data processing agreements, training records, and documentation of technical and organizational measures. Before the audit begins, the specific documents and information relevant to the assessment are defined.

What is the difference between a data protection audit and data protection certification?

A data protection audit reviews and assesses the current state of data protection and identifies potential areas for improvement. Certification under Article 42 of the GDPR goes a step further: it provides official confirmation that established certification criteria are being met. Such certifications may only be issued through the designated procedure by appropriately accredited certification bodies.

What is checked during a GDPR audit?

The areas covered depend on the agreed scope of the data protection audit. Key audit subjects include, for example, the record of processing activities, technical and organizational measures, data processing agreements, as well as deletion, role, and access concepts. Processes for data protection impact assessments and the handling of data breaches can also be part of the audit.

How does a data protection audit work?

At the start of a GDPR audit, we define the objectives and the audit framework. This is followed by an inventory and review of all relevant documentation and processes. The insights gained are then analyzed and evaluated to identify existing vulnerabilities and risks. Finally, you will receive an audit report containing the findings and concrete recommendations for your next steps.

How much does a data protection audit cost?

Costs depend on the size of your company and the complexity of your processes. For this reason, it is not possible to provide a flat rate for a data protection audit. During our free initial consultation, we will determine the exact scope and provide you with a customized quote based on those requirements.

Who is authorized to conduct a data protection audit?

A data protection audit can be conducted by internal or external auditors. The key requirements are appropriate qualifications, experience, and the necessary independence from the processes being audited. If the audit is intended to be part of an official certification under Art. 42 GDPR, additional requirements apply to the relevant certification body.

Is a GDPR data protection audit mandatory?

No, a data protection audit is generally voluntary. Companies can use it to review how they are implementing GDPR requirements and identify potential vulnerabilities. For example, the audit can serve as an internal assessment, help optimize existing data protection processes, or assist in preparing for certification.
