Castle Group International provides executive protection, private client and family services, protective intelligence, and specialized security solutions for executives, dignitaries, family offices, high-net-worth families, and organizations throughout the United States and internationally.
Our approach is discreet, intelligence-driven, and built around the individual needs of each client and assignment.
Discreet, professional protection for corporate executives, dignitaries, public figures, and private clients. Services are tailored to the individual and may include close protection, protective advances, secure movements, event coverage, and travel security.
Our objective is straightforward: provide an effective protective presence while allowing the client to maintain their schedule, responsibilities, and freedom of movement with minimal disruption.
Protection for a principal often extends to the people and responsibilities surrounding them. Castle Group provides integrated protection and trusted support for private clients, spouses, children, and family members.
Services may include family protection, secure transportation, school and activity movements, travel support, appointments, sensitive logistics, confidential deliveries, and time-sensitive personal requirements. Our professionals are prepared to protect the family while helping facilitate the practical demands of everyday life.
Effective protection begins with understanding the environment. Castle Group uses protective intelligence, threat assessment, vulnerability analysis, and advance planning to identify concerns before they become immediate problems.
Our intelligence-led approach provides clients and protective personnel with relevant information that supports sound decisions, appropriate security measures, and effective operational planning.
Safe movement requires more than a vehicle and a driver. Castle Group provides secure transportation and travel support designed around the client, itinerary, destination, and operating environment.
Capabilities include security-trained drivers, route and contingency planning, airport movements, protective advances, destination assessments, transportation coordination, and protective support for domestic and international travel.
A residence should remain a home. Castle Group develops discreet residential and estate security solutions designed around the property, family, household staff, daily routines, and identified risks.
Services may include residential protection personnel, security assessments, access-control planning, visitor and contractor coordination, emergency preparedness, and integration with the family’s broader protective program.
Some circumstances require capabilities beyond traditional executive protection. Castle Group provides tailored security support for sensitive corporate matters, elevated-threat environments, major events, workplace concerns, emergency requirements, and other complex assignments.
Through Strategic Interdiction & Surveillance, personnel, intelligence, planning, logistics, and operational resources can be coordinated according to the requirements of the mission.
Effective protection begins with understanding the client, the environment, and the risks surrounding them.
