Firm Profile > August Debouzy > Paris, France

August Debouzy
75008 PARIS

Data privacy and data protection Tier 1

August Debouzy has an established presence in the market, largely due to the presence of practice head Florence Chafiol, who has led the team since 2004 and impresses with her long track record of data protection audit matters and litigation. Crisis management, particularly in crises caused by cybersecurity breaches or data leaks, are another area of strength. The caseload attests to the group's longstanding experience in cross-border work, which account for the majority of instructions, partly because of the team's international client list which includes a strong raft of French companies operating globally alongside major players from outside of France. In July 2019, the firm hired a chief digital officer to bolster its technological services for the benefit of its clients.

Practice head(s):


The data privacy department managed by Florence Chafiol is exceptional: it has a wide range of competences that allows them to fully understand all the ins and outs of our difficulties, needs, preoccupations. Each time, they are able to provide an opinion that answers all our questions, leaving nothing answered (as others regularly do). They are inventive and capable of mobilising other forces in the law firm when needed.

The firm has a very good IT law practice, which makes them a great go-to firm for privacy matters. They have an excellent track record of seconding their lawyers on long-term assignments to in-house departments which allows for building great client relationships and for pragmatic counsel that understand in-house challenges and ways of working.

Florence Chafiol is to put it simply the expert in data & privacy in France. Her experience is vast and yet she handles everything with a calm focus that is very comforting for clients.

Florence Chafiol is outstanding. Her experience, her acumen and her profound knowledge are exceptional: never have we been disappointed in an opinion she gave.
