GDPR penalties: what to expect and how to avoid them

GDPR penalties, which can reach €20 million or 4% of a company's turnover, affect businesses, local authorities, banks, and subcontractors. These penalties are often the result of avoidable breaches, such as missing records, excessive data collection, and failure to meet deadlines. With Adequacy compliance software, however, you can structure your processes, secure your data, and reduce the risk of penalties, including those related to DORA compliance.

GDPR legal penalty

GDPR penalties can reach €20 million or 4% of a company's global turnover.

These penalties apply to companies, local authorities, banks, public organizations, and subcontractors, including those involved in DORA compliance.

Often, avoidable oversights are to blame :

  • No register
  • Excessive data collection
  • Delayed response to requests for rights

With Adequacy's GDPR compliance software, you can minimize risk.
You save time, organize your approach, and prepare for audits.

What does the GDPR say about penalties?

  • Administrative fines may be up to €20 million or 4% of global turnover
  • Formal notices requiring compliance within a specified timeframe
  • Suspension of illegal processing
  • Publication of decisions on the CNIL website or that of the competent authority

These GDPR penalties apply to all organizations, including financial institutions that are subject to banking GDPR or DORA compliance.

Example:

In 2023, a technology company was fined €1.2 billion for transferring personal data to the United States without a valid legal basis or sufficient oversight.

This type of breach can affect not only multinationals but also SMEs if there is no register or if standard contractual clauses (SCCs) are neglected.

Who is affected by GDPR sanctions?

  • All companies, including SMEs, mid-cap companies, and startups
  • Banks, insurance companies, and financial institutions
  • Local authorities, hospitals, schools, and town halls
  • Associations or foundations that collect personal data.
  • Subcontractors, including service providers, publishers, and hosting providers, if GDPR contractual clauses are absent or not complied with.

What mistakes trigger a GDPR penalty?

The top five frequent breaches are:

  • Missing, incomplete, or outdated processing register
  • The legal basis for processing is not defined
  • Inconsistent or undocumented retention periods
  • Insufficient information is provided to data subjects
  • Requests for access, rectification, or erasure are ignored or processed after the deadline

Key takeaway: collecting personal data without a clear framework can result in penalties, even in the absence of a data breach.

The sectors most affected by GDPR sanctions are tech, healthcare, banking, and local authorities

Key takeaways:

  • Employee surveillance, particularly in simplified procedures, regularly emerges as the most targeted sector (video surveillance, geolocation).
  • Commercial prospecting, including emails, cookies, and brokerage, is another frequently sanctioned sector, often due to a lack of consent and failure to provide information.
  • Non-cooperation with the CNIL is also a recurring reason for simplified penalties in 2024 and 2025.

How to avoid a GDPR penalty:

Simple preventive measures to implement:

  • Keep an up-to-date and accessible record of processing activities
  • Conduct PIAs (AIPDs) for all high-risk processing activities
  • Respond to requests for rights within 30 days
  • Train business teams in compliance
  • Secure subcontractor contracts with GDPR clauses


These actions are also required for financial sector players under DORA compliance.
