What does the GDPR say about data security on websites?.

Key GDPR obligations for websites

The General Data Protection Regulation (GDPR) establishes that any website that collects personal data from EU citizens must comply with a series of principles: lawfulness, fairness, transparency, purpose limitation, data minimization, accuracy, storage limitation, integrity and confidentiality. In practice, this means you must clearly inform the user about what data you collect and why, obtain their explicit consent (silence or pre-ticked boxes are not valid), allow them to withdraw consent at any time, and guarantee data security through technical and organizational measures. In addition, you must address the ARS rights (access, rectification, erasure), as well as the rights to restriction, portability and objection. For Spanish websites, the Spanish Data Protection Agency (AEPD) is the supervisory authority and has published specific guides on cookies, privacy policies and breach notification.

  2. 2Draft a privacy policy that complies with Article 13 of the GDPR.
  3. 3Implement a cookie banner that allows acceptance, rejection and configuration by categories.
  4. 4Add unchecked checkboxes in contact and subscription forms.
  5. 5Install an SSL/TLS certificate to encrypt the connection.
  6. 6Establish a procedure to handle ARS rights requests within a maximum of 30 days.
  7. 7Conduct a risk analysis and document the security measures applied.
  8. 8Periodically review AEPD updates and adapt your website to regulatory changes.

Fines and consequences of non-compliance

The GDPR establishes a tiered penalty system. Infringements are classified into two levels: minor (such as not informing properly) can result in fines of up to 10 million euros or 2% of the total worldwide annual turnover, whichever is higher. Serious (such as processing data without consent or not addressing user rights) can reach 20 million euros or 4% of the total worldwide annual turnover. In Spain, the AEPD is responsible for imposing penalties, and its activity has increased in recent years. For example, in 2023 it fined several companies for non-compliance with cookie regulations. In addition to fines, non-compliance can damage your brand's reputation and generate distrust among your customers. Therefore, it is crucial to invest in compliance from the start.

How to implement cookie consent according to the AEPD?.

Practical guide for the cookie banner

The Spanish Data Protection Agency (AEPD) updated its guide on the use of cookies in 2023. According to this guide, consent must be: free, specific, informed and unambiguous. This implies that the banner must appear before any non-essential cookie is loaded, must offer clear options to accept, reject and configure, and cannot use designs that induce the user to accept (for example, a large 'Accept' button and a small 'Reject' button). In addition, the user must be able to withdraw consent as easily as they gave it. Technical cookies (necessary for the functioning of the website) are exempt from consent. For analytics and advertising cookies, prior consent is required. We recommend using a consent management platform (CMP) that meets the AEPD requirements, such as Cookiebot or OneTrust, and periodically check that the banner works correctly.
