How we work

Most of the work happens before the day begins.

Good security is mostly preparation. Venues are considered in advance, routes are planned and arrangements are kept simple, so that the day carries on as normal.

Transport

Journeys that go unremarked.

We plan journeys in advance: routes, timings, pick-up points and alternatives. Vehicles and drivers are arranged to suit the client, not to be noticed. At home or abroad, the aim is a journey that is simply uneventful.

Our framework

The same five stages, every assignment.

Each assignment follows a structured process, so that decisions are informed, the service is consistent and risk is managed.

01

Assessment

We review the requirement, understand the client’s needs and identify potential risks.

02

Planning

Logistics, contingencies, communications and deployment arrangements are agreed in advance.

03

Preparation

Liaison is carried out, the team is briefed and resources are confirmed before the day.

04

Protection

Discreet delivery, with continuous awareness and proportionate measures.

05

Review

Reporting and a debrief after each assignment, so the service keeps improving.
