Personal data protection has become an essential obligation for any organization that processes information about individuals—whether companies, self‑employed professionals, public administrations, associations, or nonprofit organizations.
In today’s digital environment, where every action generates data (online shopping, apps, healthcare services, banking, video surveillance, social media, etc.), ensuring compliance with the law is both a legal responsibility and a key factor in building trust.

This guide explains what the law requires, how to comply with it, and which measures must be implemented in practice.

Fundamental principles of the general data protection regulation (GDPR)

What is personal data?

Personal data is any information that identifies or could identify a natural person. Certain special categories of data—such as health information—require enhanced protection.

1. Basic principles

Several basic principles must be followed:

1. Lawfulness, fairness, and transparency
2. Purpose limitation
3. Data minimization
4. Accuracy
5. Storage Limitation
6. Security, integrity, and confidentiality
7. Proactive accountability

2. Inventory and record of processing activities

The first practical step toward compliance with the GDPR is to identify what personal data the organization processes (customers, suppliers, employees, etc.)

Based on this, the Record of Processing Activities (RPA) is created. This document—mandatory under the GDPR—contains, among other details, the identity of the Data Controller and the characteristics of each processing activity.

This is one of the most scrutinized documents in data protection audits.

3. User information: obligation of transparency

Whenever personal data is collected, organizations must inform individuals about their rights regarding the data, the purpose of the processing, etc.

4. Valid consent

Consent must be freely given and informed, allowing individuals to choose which information they agree to share.

5. Contracts with data processors

When a third party processes personal data on behalf of the controller, a data processing agreement (DPA) must be signed. This agreement must include applicable security measures, confidentiality obligations, and instructions for data deletion.

6. Mandatory security measures

The GDPR requires the implementation of measures proportionate to the risk, both at the technical level (encryption, etc.) and the organizational level (procedures, etc.). In this regard, JakinCode has developed a risk analysis tool to comply with the requirements of data protection law.

These measures are typically aligned with standards such as ISO 27001 or the National Security Scheme (ENS).

7. Data protection officcer (DPO)

The Data Protection Officer acts as an advisor, supervisor, and liaison with the Data Protection Authorities.

8. Security breach management

A breach is any incident that compromises personal data. It must be reported within 72 hours of becoming aware of it.

9. Required documentation

To comply with the GDPR,  specific documentation must be in place. This includes, among other things, the record of processing activities, a risk analysis, policies, internal protocols, etc.

10. Penalties: one of the strictest regulatory frameworks in the world

The GDPR can impose very substantial fines for violations such as security breaches, misuse of data, or failure to uphold rights.

Complying with data protection legislation is not only a legal requirement but a key factor in building digital trust.

Organizations that integrate data protection into their processes demonstrate maturity, professionalism, and respect for individuals—key elements in the digital economy.
