What is Data Protection and Why It Matters
Data protection encompasses the practices, policies, and technologies used to safeguard personal and sensitive information from unauthorized access, use, disclosure, or destruction. In today’s digital economy, effective data protection is crucial for:
- Legal Compliance: Meeting GDPR, CCPA, and other privacy regulations
- Trust Building: Maintaining customer confidence and brand reputation
- Risk Mitigation: Preventing costly data breaches and regulatory fines
- Competitive Advantage: Demonstrating commitment to privacy as a differentiator
Core Principles of Data Protection
