The Sentinel standard
Established · London, United Kingdom
Founded by former military and police protection specialists, Sentinel operates on a single principle — that genuine security is quiet, prepared and proportionate. We assess the threat honestly, build a protective plan around it, and deliver it with officers chosen for judgement as much as for presence.
Capabilities
Seven disciplines. One protective standard.
From a single close-protection officer to a full estate programme, every Sentinel service is delivered to the same assessed, planned and accountable standard.
How we operate
Trained judgement, applied with discipline.
Equipment and credentials matter. Judgement matters more. Our officers are selected, vetted and continuously trained so that the right decision is made before a situation becomes an incident.
01
02Specialist K9
Accredited detection and patrol dogs extend our coverage, reading a venue or route before a team commits to it.
03Protective mobility
Armored vehicles and trained protective drivers keep principals moving safely between the points a plan cannot control.
Engagement
A protective programme, built in four stages.
01
Confidential consultation
We listen first. A discreet conversation establishes the principal, the concerns and the constraints — with no obligation and complete confidentiality.
02
Threat & risk assessment
We document who poses a risk, why, how likely it is and how serious. The assessment, not assumption, defines the response.
03
Protective plan
Officers, vehicles, routes, K9 and contingencies are matched to the assessment — proportionate, costed and clearly briefed.
04
Deployment & review
Teams deploy under a named operations lead, with reporting throughout and a structured review as the threat picture evolves.
