About CyberCounsel 

We are three specialist, highly qualified, independently recognised lawyers: Dean Armstrong QCDan Hyde and Sam Thomas

Our work led us to identify cyberlaw as a distinct and developing area of law and we wrote the first book explaining what it was and how it could be applied to tackle the vast array of cyber threats and attacks. We were the pioneers of cybersecurity law and practice and leaders in the field. As well as publishing the first textbook written by legal practitioners on all aspects of cyber law, we contribute to national and international journals and deliver lectures on this new area of law giving us practical insight to add to our academic expertise.

We are supported by leading national and international law firm Penningtons Manches, where Dan is a partner, and the acclaimed top tier barristers’ chambers 36 Group where Dean is a leading barrister (Queens Counsel). Sam is a junior barrister at the leading set of 2 Bedford Row. Together we are CyberCounsel.

Our versatility and knowledge means we can quickly assess what your case requires and assemble a team that is lean for smaller instructions or scaled up for the larger matters.
