Firm Profile > Froriep > Zurich, Switzerland


Data privacy and data protection Tier 2

The Froriep team 'sets the focus on the client's need' and is 'very knowledgeable' on GDPR issues, with 'prompt and substantive' analysis on matters ranging from data security breach incidents to blockchain technology data protection advice. Nicola Benz leads most advisory work, including on Vetri Foundation's consumer platform for personal data, Hiag AG's cloud and digital infrastructure, and a data protection compliance programme for the Swiss Equestrian Federation. Benz and 'meticulous' associate Cornelia Mattig 'are extremely customer-focused with a practical, hands-on mentality'. Ronald Kogens made partner in July 2019.


Legal counselling particularly on data protection started late 2017, ever since they demonstrated their excellence in not only Swiss and EU GDPR, but also international data protection competencies. Worthy of special mention is that FRORIEP always puts the protection of our interest as highest priority and sets the focus on the client’s need. This is a valuable strength in comparison to other firms and much appreciated from our side.

The strength of a firm is characterised by the competence of its employees. In particular, Nicola Benz and Cornelia Mattig distinguish with outstanding excellence. It is a pleasure to work with such dedicated and passionate individuals. In addition to the ordinary skills of structured working method, communication ability and quick response times, Nicola and Cornelia are extremely customer-focused with a practical, hands-on mentality. To us this fundamental understanding and shouldering responsibility is highly valuable and means that they go far beyond the requirements advising on certain parts of our business we have not even thought about yet. Their critical thinking is a beneficial contribution and reflection on our work. Nicola and Cornelia give precise advice as well as clear explanations of what the purpose is and why exactly it is recommendable to be this way; a great addition to their outstanding customer service.

The team is very knowledgeable in GDPR issues and their analysis has been prompt and substantive.

The partner Nicola Benz is very engaging and prompt when responding to requests, with respectable working ethics. The communication is very clear and direct. Associate Cornelia Mattig was meticulous in terms of execution and very responsive as well. I would recommend the team for GDPR issues that has to be taken care of by international organisations based in Switzerland.

Our demand was review all GDPR documents established by another law firm which were not suitable for us at all. Changing and modifying articles usually take more time and attention, but Froriep did it in a very short time limit without sacrificing quality.

Ms Cornelia Mattig was professional and conscientious. She listened to client requests and adapted the clauses to business needs. She was always available and respected the schedule. It was a great pleasure to collaborate with her.

Inclusiveness and diversity are and have always been core values of our firm and shape the way we run it.

FRORIEP was the first major commercial law firm in Switzerland to have a female partner. FRORIEP is also the first such firm to have appointed a female managing partner, and also the first to have a female successor to a female managing partner. We are committed to creating a working environment in which all individuals are treated with respect and fairness and have the opportunity to give their best and be appropriately recognised, rewarded and supported for their contributions.

We are fortunate to have 7 female partners, including our Managing Partner along with two Office Managing Partners and an ex-Managing Partner. Nearly one-third of our partnership is composed of women. This allows FRORIEP to be recognised as one of the leading Swiss business law firms in terms of female representation and leadership and one of the top female to male partner ratios.

For the past 5 years the London office has recruited trainees from all backgrounds and regions of the world (UK, China, Mauritius, Zimbabwe, France, USA, Germany, Ukraine, Ivory Coast, etc.), simply based on their CV and academic achievements. We discovered how enriching and motivating this experience is for all.

CLIENT: Family Office Palmarium

CLIENT: Njara Zafimehy, Founder & CEO, WhatRocks Foundation™


TESTIMONIAL: Froriep has been very responsive to our communications, very detail-oriented and very articulate: this was all the more critical to us that we have very limited knowledge of the Swiss law. Froriep has made very useful introductions to potential business partners, clients and investors and is very well connected with the Geneva canton authorities, which tremendously facilitates and accelerates our progress.

Julie Wynne is very pragmatic and adapts easily when business conditions and strategy change, which is very reassuring and comfortable for entrepreneurs like us who do business in a fast-paced, ever-changing business environment.

CLIENT: Catherine Henry, GENUS


TESTIMONIAL: As we stepped into new Business Launch, we sought out a lawfirm to assist, coach and advise through the steps. Froriep came highly recommended and has become one of…if not the best, recommendations I have ever received.

CLIENT: Earthworm Foundation, Catharina Plummer


TESTIMONIAL: Julie Wynne provided us with great counsel for our non profit as we determined the legal impacts of switching over from a UK charity to a Swiss Foundation. Julie’s depth of knowledge regarding the laws and her genuine interest in the work we do convinced us she would be the best person to guide us. Shortly after having met her, our organisation overwhelmingly chose to engage with Froriep. We were especially pleased with how the team walked us through every detail of the process and their support through it.
