Glevum Security has acquired Avantguard Security, a well‑established security provider based in Arundel, West Sussex. Founded in 2009, Avantguard has developed a strong reputation for delivering professional, people‑focused security services supported by detailed reporting, modern technology and a commitment to raising standards across the private security industry.
Avantguard works with a broad client base that includes insurers, manufacturing firms, education providers, hospitals, local councils and major property and facilities companies across West Sussex and the wider region. Tony Woolcott, who has led the business for many years, will remain with the company.
Commenting on the announcement, Tony said: “Joining Glevum Security is a positive step for Avantguard. Our focus has always been on delivering a personal, professional service built on strong values and high standards, and we see those same principles reflected across the Glevum group. I look forward to working together to support our clients and strengthen the services we provide across the region.”
The acquisition brings Avantguard’s regional expertise into the wider Glevum group, now operating across the South East and South West. The expanded footprint enhances the group’s ability to deliver consistent, proportionate and joined‑up security services to organisations across the UK.
