Our Operatives

Our services are delivered by professionals selected through a rigorous four-stage recruitment process, ensuring only those of exceptional calibre join our ranks. Each operative holds a current Close Protection SIA licence and Enhanced DBS clearance, with experience operating at the highest levels of the security profession.

Seamless Integration

The nature of our clientele demands absolute discretion and the highest standards of personal conduct. Our operatives are selected not only for professional competence but for their ability to integrate seamlessly into any environment whilst maintaining their protective role.

Protective Intelligence

Each of our services is supported by a continuous intelligence function — a dedicated capability that observes, anticipates and informs.

Our analysts work alongside purpose-built systems that monitor the matters most likely to affect our principals: open-source reporting and local sentiment along planned routes, mentions of the principal or family across the open and closed web, planning and public records that may inadvertently expose a residence, vehicle and access patterns around estates and vessel movements in proximity to private yachts. Volume is handled by the systems; judgement remains entirely with our people.

It is not a service we offer separately. It is simply how we work.

Close Protection

Personal protection tailored to the individual, their family and their routine. Operatives are chosen for their ability to remain unobtrusive while maintaining complete vigilance; the protection is evident in its effect and rarely in its appearance.

Residential & Estate Security

The comprehensive protection of private estates and family residences — from discreet monitoring to the full coordination of estate security — undertaken in a manner that preserves the character of the household. We integrate with existing staff rather than imposing upon them, ensuring that the residence remains as it should, a home.

Travel Security

Secure transportation and travel coordination, in the United Kingdom and abroad. Advance reconnaissance and route planning ensure safe passage without constraining the freedom of those who travel.

Risk and Security Consultancy

Considered assessment of a property, a routine or an exposure, with clear and proportionate recommendation. Surveys are conducted to established British Standards and reported without alarm or excess.

Surveillance & Counter-Surveillance

Discreet observation and the detection of hostile interest, employing both traditional tradecraft and modern technical measures, ensuring that a principal’s movements and associations remain their own.

Maritime Security

Protection for private yachts and vessels, provided by Ship Security Officers qualified to the ISPS Code, maintaining security at berth, at anchor and underway.

Sporting Estate and Event Security

Seasonal security for shooting estates and private occasions: the planning of a season, the screening of guests, coordination with visiting protection teams and discreet coverage that leaves the convivial character of the day entirely intact.
