Privacy-enhancing technologies (PETs) are tools and techniques designed to protect individuals' privacy by minimizing the collection, use, and sharing of personal data. These technologies help organizations comply with data protection regulations while still allowing for data-driven insights. 
Examples of PETs include encryption, anonymization, pseudonymization, access controls and [differential privacy](https://www.cookieyes.com/knowledge-base/privacy-tech/what-is-differential-privacy/), which ensure that [sensitive information](https://www.cookieyes.com/blog/personally-identifiable-information-pii/) remains private, even when data is analyzed or shared. PETs are critical in reducing privacy risks and enhancing data security in both online and offline environments.
