A GDPR audit for software is more than just an annoying duty. It is a strategic necessity 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 significant 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 requirements of the GDPR.
• Risk minimization: You identify 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.

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 documented.
• Documents check: View existing documentation such as processing directories (VVT), data protection impact assessments (DSFA) and contracts with processors (AVV). Testing
