Engaging with cybersecurity has become essential for every type of business whatever their size or sector. Increased digitalisation and new technologies are allowing businesses to grow rapidly. However, cyber risks increase in tandem with these opportunities and every modern business should expect to experience a data breach.  

CMS has advised on over 500 cyber incidents to date and covers over 50 jurisdictions as part of our global cyber network.  Our approach is to tackle cyber issues holistically and globally.

Cyber from every angle

  • Breach incident response

    We’re available 24/7/365 to coordinate an immediate response to a breach. We advise on how to minimise the risk of regulatory sanction or litigation from the outset.

  • Cyber and data protection compliance

    Before an incident, we prepare businesses through audits, eLearning, training and breach response plans. Post-incident, we provide ongoing health checks and reviews.
