Every organization handling European Union citizens’ personal data faces a regulatory framework so comprehensive and punitive that a single violation can result in fines reaching 4% of global annual revenue—or €20 million, whichever is higher. Since its implementation in May 2018, the General Data Protection Regulation has fundamentally transformed how businesses worldwide approach data privacy, with cumulative fines reaching €5.88 billion by January 2025, including the record-breaking €1.2 billion penalty against Meta Platforms Ireland Limited.
The General Data Protection Regulation (GDPR) Implemented on May 25, 2018, replaced the 1995 Data Protection Directive and established uniform data protection standards across all 27 EU member states plus Iceland, Liechtenstein, and Norway within the European Economic Area.
The GDPR’s territorial scope extends beyond EU borders through its “extraterritorial effect,” meaning that any organization processing EU residents’ personal data must comply regardless of their physical location. This global reach has made GDPR a de facto international standard, influencing privacy legislation worldwide and forcing multinational corporations to adopt comprehensive data protection programs.
At its core, GDPR is built on seven fundamental principles that govern all data processing activities: lawfulness, fairness, and transparency; purpose limitation; data minimization; accuracy; storage limitation; integrity and confidentiality; and accountability. These principles work together to ensure that personal data is processed ethically, securely, and with full respect for individual privacy rights.

Lawful Bases for Processing
Article 6 establishes six lawful bases for processing personal data:
| 1. Consent | 2. Contract |
| – Must be freely given, specific, informed, and unambiguous – Requires clear affirmative action (no pre-ticked boxes) – Must be easily withdrawable – Children under 16 require parental consent (Member States may lower to 13) | – Processing necessary for contract performance – Includes pre-contractual measures – Must be genuinely necessary, not just convenient |
| 3. Legal Obligation | 4. Vital Interests |
| – Required by EU or Member State law – Must specify the legal provision – Cannot be used for voluntary compliance | – Necessary to protect life or prevent serious harm – Typically reserved for emergency situations – Rarely applicable to commercial processing |
| 5. Public Task | 6. Legitimate Interests |
| – Processing by public authorities – Exercise of official authority – Must be established by law | – Most flexible but requires balancing test – Must demonstrate legitimate business need – Cannot override data subject rights – Requires impact assessment |

FAQs
What are the main differences between GDPR and other privacy laws?
GDPR differs from other privacy laws in several key ways: its extraterritorial scope applies globally to any organization processing EU residents’ data, regardless of location; the penalty structure allows fines up to 4% of global revenue or €20 million; it grants comprehensive individual rights including data portability and the right to be forgotten; and it requires explicit consent rather than implied consent for data processing.
How long do organizations have to respond to data subject requests?
Organizations must respond to data subject access requests within one month of receipt. This timeline can be extended by an additional two months for complex requests or high volumes, but the organization must inform the data subject of the extension and reasons within the initial one-month period. The first copy of personal data must be provided free of charge.
What constitutes a personal data breach under GDPR?
A personal data breach is any security incident that leads to accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access to personal data. This includes cyberattacks, employee errors, system failures, and physical theft of devices containing personal data. Organizations must notify supervisory authorities within 72 hours and affected individuals without undue delay if the breach poses high risk.
When is a Data Protection Impact Assessment required?
DPIAs are mandatory when processing is likely to result in high risk to data subjects, including: systematic and extensive profiling with legal effects; large-scale processing of special category data; systematic monitoring of publicly accessible areas; use of new technologies; processing that prevents data subjects from exercising rights; or when combining datasets from different sources.
Can organizations transfer personal data outside the EU?
Yes, but only with adequate protection measures. Data can be transferred to countries with EU adequacy decisions without additional safeguards. For other countries, organizations must implement appropriate safeguards such as Standard Contractual Clauses, Binding Corporate Rules, or obtain explicit consent. The transfer must also have a lawful basis under Article 6.
What are the requirements for valid consent under GDPR?
Valid consent must be freely given, specific, informed, and unambiguous. It requires a clear affirmative action (no pre-ticked boxes), must be easily withdrawable, and should be separate from other terms and conditions. For children under 16 (or lower age set by Member States), parental consent is required. Consent must be documented and renewable.
How does GDPR apply to artificial intelligence and automated decision-making?
GDPR Article 22 grants individuals the right not to be subject to purely automated decision-making with legal or significant effects. When such processing occurs, organizations must provide meaningful information about the logic involved, implement human oversight, and allow individuals to challenge decisions. AI systems using personal data must comply with all GDPR principles including data minimization and accuracy.
What are the key elements of privacy by design?
Privacy by design requires embedding data protection considerations from the earliest stages of system development. Key elements include: implementing appropriate technical and organizational measures; considering the state of technology and implementation costs; ensuring data minimization and purpose limitation; providing transparency and user control; maintaining full functionality while protecting privacy; and demonstrating accountability through documentation.
