Latest news & insights:

Cyber security and cyber crime are among the biggest issues confronting businesses and other organisations today. The law faces huge challenges to keep up with the rapid development of technology which provides opportunities for the misuse of both the internet and computers for commercial gain, espionage or other criminal purpose.

This translates into a variety of threats to intellectual property, confidential information, personal data, hardware and software; in fact everything valuable to an individual or organisation may be at risk from cyber-attacks, data breaches or fraud. There is a further risk to those who fail to protect their property or client data when they fall victim to an attack. Increased global cyber regulation through the General Data Protection Regulations (GDPR)  and the huge fines that will be imposed on those who do not comply, mean that businesses could potentially face insolvency from penalties of the greater of 20 million euros or 4% of global turnover. They should obtain expert help now to ensure they meet the new uprated standards.

At Penningtons Manches, our lawyers are leaders in the field and at the vanguard of cyber security and cyber crime. We recognised cyber law as a distinct and emerging legal specialism at a time when its parameters were first being defined and our practice consistently offers clients both technical excellence and a practical understanding of the key issues. Partner Dan Hyde authored the first (and only) book on UK cyber security law and how it is applied across the entire range of scenarios.

Close collaboration between our data protection and privacy, reputation management, commercial dispute resolution and white collar investigations teams ensures our lawyers are able to bring their knowledge and experience across the vast spectrum of civil, criminal and regulatory law as it applies to this area. 

We defend and prosecute, representing individuals or organisations in relation to matters arising from a data breach or cyber–attack, whether internal or external, and work seamlessly with in-house teams whenever necessary. Our lawyers also provide preventative advice and regularly implement cyber security policies as well as IT training.

We offer expert advice on:

  • employee liability and protection
  • data security
  • control mechanisms for embedded devices
  • compliance and regulation
  • preventative measures and policies
  • data breach response
  • commercial espionage
  • investigation of incidents
  • cyber security disputes
  • cyber crime prosecutions
