    This area covers how organisations collect, use and protect personal data, and how to respond if something goes wrong. A solicitor in privacy and data security drafts and negotiates data processing agreements, conducts data protection impact assessments, advises on subject access requests, breach notification duties and adherence to the UK GDPR and the Data Protection Act 2018. They review privacy notices, data sharing arrangements and security measures to limit risk, and represent clients in investigations or disputes when data rights are at stake.
