GDPR Security for Spanish Websites: Protect Your Customers' Data.

Practical guide to comply with GDPR on your website and avoid fines of up to 20 million euros.

The General Data Protection Regulation (GDPR) requires all websites that process data of European citizens to apply strict security measures. At SEO7ES, with 9 years of experience in Valencia, we help you put privacy, cookie and consent policies in place. Compliance avoids fines and, on top of that, builds trust with your customers.

Quick answer

To comply with GDPR on your Spanish website, you need: 1) An accessible privacy policy, 2) A cookie banner with granular consent, 3) SSL/TLS encryption, 4) Forms with explicit acceptance checkboxes, 5) A right of access, rectification and erasure (ARS) that is easy to exercise. Penalties can reach 20 million euros or 4% of annual turnover. At SEO7ES we advise you from Valencia for all of Spain.

In this guide we break down the key GDPR requirements for Spanish websites. We answer the most frequently asked questions: what does the law say? How do you obtain consent? What happens if you do not comply? We include a table with penalties by severity, practical steps to adapt your website and a quote from the AEPD on the importance of data protection. At the end, a summary and an FAQ with 13 essential questions. All designed so you can apply the measures right away, whether your business is in Valencia or anywhere in Spain.

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 collecting 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, that means clearly informing the user about what data you collect and why, obtaining their explicit consent (silence or pre-ticked boxes do not count), letting them withdraw consent at any time and guaranteeing data security through technical and organizational measures. You must also address the ARS rights (access, rectification, erasure) and the rights to restriction, portability and objection. For Spanish websites, the supervisory authority is the Spanish Data Protection Agency (AEPD), which has published specific guides on cookies, privacy policies and breach notification.

GDPR security Spanish website: cookie banner with accept and reject options
Example of a cookie banner compliant with the AEPD guide.
  1. 1Identify all personal data collected by your website (forms, cookies, analytics).
  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 sets out a tiered penalty system. Infringements fall into two levels. Minor ones (such as failing to inform properly) can bring fines of up to 10 million euros or 2% of total worldwide annual turnover, whichever is higher. Serious ones (such as processing data without consent or ignoring user rights) reach 20 million euros or 4% of total worldwide annual turnover. In Spain, penalties are imposed by the AEPD, which has stepped up its activity in recent years. For example, in 2023 it fined several companies for breaching cookie rules. Beyond fines, non-compliance damages your brand's reputation and breeds distrust among your customers. That is why it pays 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 that guide, consent must be free, specific, informed and unambiguous. That means the banner appears before any non-essential cookie is loaded, offers clear options to accept, reject and configure, and does not use designs that nudge the user toward accepting (for example, a large 'Accept' button and a small 'Reject' one). Withdrawing consent must be as easy as giving it. Technical cookies (needed for the website to work) are exempt from consent. Analytics and advertising cookies require prior consent. We recommend using a consent management platform (CMP) that meets the AEPD requirements, such as Cookiebot or OneTrust, and checking periodically that the banner works properly.

Expert opinion

«A consent banner works only when refusing is as easy as accepting. If the reject button hides on a second screen you do not have consent, you have an imitation of it, and a regulator sees that immediately.»
