GDPR audit for software: preparation and implementation

Software is ubiquitous in today's digital world. However, with increasing digitalization, data protection needs are also growing.

In specific, the General Data Protection Regulation (GDPR) presents great challenges to companies.

A GDPR audit for software is a decisive step in ensuring compliance and avoiding high fines.

In this post, you will learn how to prepare for such an audit, perform it successfully and why a GDPR-compliant software is essential for your company.

Why is a GDPR audit so important for software?

Software is ubiquitous in today's digital world.

A GDPR audit for software is more than just an annoying duty. It is a strategic need to minimize risks and strengthen the confidence of customers and partners.

The non-compliance of the GDPR can lead to sensitive penalties of up to EUR 20 million or 4% of the global annual turnover.

Such fines can seriously jeopardize the existence of a company. In addition, an audit protects against major reputational damage that may arise due to data breaches.

A single incident can sustainably shake the confidence of customers and business partners and lead to a sensitive competitive disadvantage.

The advantages of a software audit at a glance:

• Legal security: You make sure your software meets the strict needs of the GDPR.
• Risk minimization: You find and fix potential vulnerabilities before they become a problem.
• Confiscation: You show to your customers and business partners that you take the protection of your data seriously.
• Competition advantage: A DSGVO compliant software can be a decisive selling argument.

Preparation: The key to successful audit

A careful preparation is half the rent and sets the foundation for a successful audit.

Before starting the actual audit, you should systematically compile all relevant information and documents. This not only helps the entire process, but also ensures precise and meaningful results.

However, insufficient preparation can lead to delays, incomplete analyses and ultimately to an ineffective audit.

Important steps in the preparation phase:

• **Rating:**Record all software applications that process personal data. These include not only the central business applications, but also smaller tools, plugins and interfaces. Any component that comes into contact with personal data must be identified and recorded.
• Documents check: View existing documentation such as processing directories (VVT), data protection impact assessments (DSFA) and contracts with processors (AVV). Testing.
