Profile
Mossack Fonseca is a Panamanian law firm that provided corporate and fiduciary services to clients worldwide. Its core offerings included the incorporation of offshore companies, registration of ships and aircraft, and the appointment of nominee directors and shareholders. The firm also delivered legal advice on wealth structuring, estate planning, and international tax considerations. Clients accessed these services through the firm's headquarters in Panama City and its network of affiliated offices.
Over its history, Mossack Fonseca claimed to have established hundreds of thousands of offshore entities for a diverse international clientele. The 2015 breach exposed the extent of its record‑keeping, with attackers copying 11.5 million documents totaling 2.6 terabytes. This volume of data reflects the large scale of the firm’s administrative and client files. While specific employee counts or revenue figures are not disclosed in the available sources, the breach magnitude underscores the firm’s substantial operational footprint.
Mossack Fonseca distinguished itself by specializing in the creation of confidential corporate vehicles designed to provide privacy and asset protection. The firm highlighted its expertise in navigating varied regulatory regimes and tailoring structures to meet client objectives. Its reputation for discreet offshore services positioned it prominently among corporate service providers, particularly for clients seeking jurisdictions with strong secrecy laws. Despite offering lawful services, the leaked documents sparked global debate about the use of offshore entities for concealment of wealth.
The organization was a privately held partnership founded by Jürgen Mossack and Ramón Fonseca Mora, without a publicly listed parent or subsidiary structure described in the sources. After the 2015 email server hack, Mossack Fonseca contracted external security consultants to investigate the breach and implement preventive measures. The sources do not indicate any subsequent changes in ownership, governance, or affiliate relationships resulting from the incident.
