It safeguards natural persons' personal data across the EU and beyond, replacing the 1995 Data Protection Directive. GDPR employs a principles-based, accountability-driven approach with extraterritorial scope, applying to any entity processing EU residents' data.
Key Components
- **Seven core principleslawfulness/fairness/transparency, purpose limitation, data minimization, accuracy, storage limitation, integrity/confidentiality, accountability.
- **Data subject rightsaccess, rectification, erasure ('right to be forgotten'), portability, objection, restriction.
- Obligations include DPO appointment, DPIAs for high-risk processing, ROPA maintenance, 72-hour breach notifications.
- Enforced by DPAs via fines up to €20M or 4% global turnover; no formal certification but demonstrable compliance required.
Why Organizations Use It
Mandatory for EU data processors worldwide, minimizing legal risks and fines. Enhances trust, supports Digital Single Market, sets global 'gold standard' influencing laws like LGPD/CCPA. Drives risk management, innovation balance, reputation.
Implementation Overview
Gap analysis, policy/tech updates, training, audits. Applies universally by org size/industry if handling EU data. Resource-intensive, 18-24 months typical; ongoing DPA oversight.
ISO 20000 Details
What It Is
ISO/IEC 20000-1:2018 is the international certifiable standard for establishing, implementing, and improving a service management system (SMS). It provides auditable requirements for managing the full service lifecycle—planning, design, transition, delivery, and improvement—to ensure consistent service quality.

- Enables market differentiation, procurement wins, integration with ISO 9001/27001.
- Meets stakeholder demands for verifiable governance in IT/cloud/services.
Implementation Overview
- Phased: gap analysis, design, deployment, audits (12-18 months typical).
- Applies to all sizes/industries; requires leadership, training, tooling.
- Certification demands evidence of effective SMS operation.
