GDPR UK Details
What It Is
UK General Data Protection Regulation (UK GDPR) is the UK's post-Brexit data protection law, adapting EU GDPR via Data Protection Act 2018. Enforced by ICO, it establishes a binding regulation for personal data processing with risk-based, accountability-focused approach, applying to UK-established and extra-territorial entities targeting UK individuals.
Key Components
- Seven core principles: lawfulness, purpose limitation, minimisation, accuracy, storage limitation, security, accountability.
- Data subject rights: access, rectification, erasure, portability, objection.
- Controller/processor obligations: RoPA, contracts, DPIAs, breach reporting.
- Compliance via documentation, audits; fines up to 4% global turnover.
Why Organizations Use It
Mandated for compliance, reduces regulatory fines (£17.5M max), enhances trust, mitigates breaches. Drives efficiency via data mapping, supports cross-border ops.
Implementation Overview
Phased: governance, mapping, policies, DPIAs, training, monitoring. Applies universally; ICO audits enforce. Ongoing, scalable by size.
