Individual bodyguards
Covert protective details
Beyond the usual call for bodyguards, many clients today feel uneasy about conspicuous or “obvious” security measures. Some even ask that their protectors remain so unobtrusive that they scarcely notice they are there. Male clients, for instance, can find it awkward when a male bodyguard visibly guards a female companion or spouse, and may insist that the “big guys” stay in the background and avoid direct interaction.
To meet this need, we offer—alongside standard close protection—a specialised service known as Covert Protection. In this model, a team of operatives (typically more than one) proactively scans, identifies, and neutralises potential threats in the client’s surroundings, preventing risk long before the client’s safety is compromised.
Many clients prefer this discreet solution because it provides effective protection without attracting attention—ideal for anyone whose public image could suffer from overt security measures.
