TMT

VISCHER stands out for its handling of digital transformation, cloud adoption and data governance across Switzerland’s most regulated and technology-driven sectors. The team is regularly engaged on mandates involving cutting-edge technologies, including AI development, cybersecurity innovation and large-scale cloud migrations. The practice is led by Rolf Auf der Maur, noted for his work on digitalisation, online business models and media regulation, alongside David Rosenthal, a leading authority on data law, GDPR, AI and complex IT and cloud projects, who also represents clients in technology-related arbitration. They are supported by the ‘deeply intelligent’ Elias Mühlemann, whose expertise spans regulatory aspects of TMT, cloud-based service offerings and digital copyright. Samira Studer is another ’standout’ individual, called upon for her knowledge of the Swiss Data Protection Act and GDPR.
