GSSI
Global Shield Security International
Global Shield Security International (“GSSI”) is a Switzerland-based private security and executive protection organization headquartered in Zurich.
The company was founded by a group of former Swiss military officers, U.S. Executive Protection (EP) specialists, European corporate security advisers and risk management professionals with the objective of providing lawful, compliant and internationally standardized protection services to high-net-worth individuals, corporate executives, investors and their families.
GSSI operates under a multi-jurisdictional compliance framework, combining Swiss regulatory discipline, U.S. EP doctrine, UK licensing standards and EU private security regulations.
The organization focuses on cross-border and overseas protection assignments, rather than local guard services, and is structured to support clients who travel frequently across Europe, Asia, the Middle East and North America.

The core mission of GSSI is to ensure that protective services are delivered:
GSSI’s Swiss governance model emphasizes transparency, accountability and alignment with the requirements of SECO (the Swiss State Secretariat for Economic Affairs), particularly in relation to security services provided outside Switzerland.
The U.S. team includes former military personnel, former law enforcement officers, EP instructors and medical responders. Many operators hold relevant state-level licenses (e.g. EP-related certifications, where applicable), and undergo regular re-qualification and skills audits.
GSSI’s operational and advisory teams consist of:
All personnel must pass:

Swiss SECO / PSSA – governance of private security services provided abroad, with obligations relating to transparency, documentation and reporting
UK SIA Close Protection licensing – setting competence standards for close protection operatives
U.S. Executive Protection and related state-level licensing, where applicable
EU private security regulations and accreditation in various member states
In Southeast Asia, Mr. Andy Ngu King Chung has been appointed as GSSI’s Authorized Regional Representative for Southeast Asia.
