First Security has extended the range of services provided to 30 St Mary Axe, London – better known as The Gherkin – to include the mailroom and delivery bay, as part of the management's strategy to include both elements as a key function of security rather than administration.

First Security officers have worked at the Gherkin since 2004, providing security on a 24/7 basis. Their responsibilities include CCTV monitoring, physical security, staffing the building control centre, and additional services such as manning the main reception out of hours.
