Data compliance regulations are legal frameworks that organizations must follow to ensure the safe and ethical handling of personal and sensitive data. These regulations vary by region and industry, such as the GDPR in the European Union, HIPAA for healthcare in the U.S., CCPA in California, and the Digital Personal Data Protection (DPDP) Act in India. They typically mandate data transparency, user consent, security controls, and breach notification protocols. Compliance helps protect consumer privacy, reduces the risk of data breaches, and builds organizational trust. Non-compliance can result in heavy penalties, legal action, and reputational damage.
