About

David Cook advises on contentious cyber security, privacy, and data protection matters and has done for over 15 years.  He acts for a global client-base that routinely turns to him for advice on a cross-border basis and with significant and complicated legal, regulatory, and reputational implications.

David’s practice covers the range of cyber risk management, governance, and incident reporting issues.  He has extensive experience coordinating high profile and sensitive cyber security incident response and data protection regulatory engagement.  He is routinely engaged to support with regulatory notification, internal investigation and support and representation in the civil and the criminal law jurisdictions.

His practice extends to cyber security technical controls work, which is an area of expertise informed by his background in learning to code at the age of seven years old through to his time spent in a Big 4 professional services consultancy.  That thorough technical understanding underpins David’s position at the forefront of this area of law.

He has delivered training to a number of police teams in how to effectively investigate and evidence cyber crime.  He was invited by Keir Starmer KC, the then Director of Public Prosecutions, to a roundtable meeting of experts considering CPS policy on the prosecution of cyber crime.

He has delivered seminars and key-note presentations to the University of Manchester, University of Derby, Henley Business School and at the National Cyber Security Centre funded centre of cyber security excellence at the University of Lancaster.
