Data Protection, Privacy and Cyber Security

Key Contacts view all


With significant reputational issues at stake, data protection, privacy and cyber security is an increasingly complex and challenging management issue for all businesses, including in light of the GDPR and recent similar initiatives in other jurisdictions, the increasing use of biometics, the ubiquity of cloud computing and the emphasis on data analytics.  Our cross departmental Data Protection, Privacy and Cyber Security group, which is led from our Technology and Innovation practice, is made up of specialists who provide advice to our wide range of clients, including several of the world’s leading multi-nationals and financial institutions, on data protection and privacy law and in relation to cyber security issues.   

A leader in its field, the Data Protection, Privacy and Cyber Security group advises on the full range of matters, from specific and strategic GDPR and ePrivacy compliance advice, through full compliance reviews, to advising clients on privacy by design for new products and services, data strategies for marketing, and the implementation of cookie and similar technologies.  Addressing data protection issues in structuring contractual frameworks, including in outsourcing and cloud arrangements and in multi-jurisdictional transactions, as well as guiding clients on ways of implementing compliant cross-border data flows, is a frequent focus of the Group.  

The Group provides strategic and practical advice to clients dealing with data subject rights, in particular data subject access rights, in both contentious and non-contentious situations, which we manage in conjunction with Matheson’s Digital Services Group.  We advise on data security breaches and interactions with Data Protection Commissioner, having advised on multiple significant security breach incidents, data protection audits and “dawn raids”, investigations, and information and enforcement notices.
