Corporate Security

A courteous, visible security presence can be necessary to help staff and visitors feel welcome, valued, informed and safe. Our corporate security officers are always well presented to reflect their surroundings and we pride ourselves on hand selecting personnel to suit each role. Good communication skills are vital, as is courtesy, kindness, watchfulness and firmness when necessary. Roles often include access control, welcoming and directing visitors and always being prepared for the unexpected.

Night-Time Economy

Selecting the right personnel for door supervision is key to helping maintain that delicate balance of security and safety, while not interfering with the enjoyment of a venue’s guests. During our full site survey and risk assessment, we get to know our client’s needs, their customers and the venue layout before deploying our fully-trained and SIA licensed door supervisors. We try to prevent security issues before they happen, but when an issue does arise, our officers will take appropriate measures quickly, with courtesy and firmness.

Construction Security

We provide highly visible and well-trained security officers to protect construction sites. We monitor access to the site and do regular patrols, often installing a touch point system with officers moving around the site hourly. Our main aim is to help Site Managers keep premises safe and for our presence to deter thieves and vandals, particularly once workers have gone home for the night.
