With significant reputational issues at stake, data protection, privacy and cyber security has become an increasingly challenging management issue for all businesses, particularly in the context of the GDPR, the increasing use of cloud computing, CCTV and biometics and the emphasis on data analytics.  Our cross departmental Data Protection 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 the evolving area of data protection and privacy law and in relation to cyber security issues.

Matheson’s Data Protection and Cyber Security group is a leader in its field, dealing with a wide-range of matters including specific and strategic compliance advice, including in relation to the GDPR, full compliance reviews, implementing contractual frameworks for outsourced data processing arrangements, assisting clients in achieving privacy by design in new products and services, handling cross-border data flows, and dealing with data security breaches and data subject access requests, including in contentious situations.  We also advise in relation to the privacy and profiling issues which arise in connection with marketing, including in connection with the use of cookies and similar technology.

We have extensive expertise in relation to international data transfers, and have advised on the use of standard contractual clauses, binding corporate rules and the EU-US Privacy Shield, including in the context of multi-jurisdictional data flows and transactions.

The Group has managed and advised on multiple significant security breach incidents, data protection audits and “dawn raids”, and is experienced in dealing with Data Protection Commissioner investigations, and information and enforcement notices.
