ENISA: PETs controls matrix - A systematic approach for assessing online and mobile privacy tools

Following previous work in the field of privacy engineering, in 2016 ENISA defined the ‘PETs control matrix’, an assessment framework and tool for the systematic presentation and evaluation of online and mobile privacy tools for end users. The term ‘PET’ is used in the context of this work with a narrow focus, addressing standalone privacy tools or services (and not the broader concept of privacy enhancing technologies).
