Basic tools for accountability compliance
The AEPD has developed tools and help material to assist with compliance with general data protection regulation for small businesses, entrepreneurs and developers, and other types of controllers. This section lists those tools that are common to all types of processing. In the section "Guides, reports and technical notes" you can find specific material that extends their scope to specific treatments, technologies or controllers.
In any case, controllers and processors should not forget to verify that they comply with all the requirements and obligations that guarantee compliance with GDPR and national rules on data protection.
Risk management and Impact Assessment regarding Data Protection
