Full transparency, total trust, and protection you can rely on — that's the Overt promise.
Our Happy Customers
Mike Mitchell Company Director United Worldwide Logistics
"As a company who holds other client's stock and valuable trucks and trailers, security is a necessity. At the drop of a hat, Overt Security stepped in and have safeguarded our premises, vehicles and all medical stock. I would like to give a big thank you to Overt and the guards, within times of worry. You have saved myself and my clients from one less major worry knowing our stock and valuables are secure and safe."
Hannah Bevan-Mohaffel Co-Chair / Festival Organiser Sully Village Group "We hired Overt Security to work with us at our first ever Sully Festival — Sullyfest. All of the staff were extremely professional and friendly and happy to help with anything we asked of them. All incidences were dealt with professionalism and we received many complimentary comments from visitors and volunteers about the service they provided. As the festival organiser, I felt reassured throughout the day knowing that the Overt staff were nearby and fully in control. I would highly recommend them and have booked them for all future events."
Jordana Weekley Senior Functions Coordinator National Museum Of Wales "I was recommended Overt Security by a friend, they met with us on the day of enquiry and came to view the venue. We discussed the events held at the Museum and they were able to suggest and guide us with the staff set up, which was a great help. Upon request, Overt also provided Welsh speaking security guards, which was exactly what we were looking for. We have since used Overt Security on a number of occasions and will continue in the future."
Jon Adams Operations Director Academy Coffee / Loft Co "We have been using Overt Security for the past three years to provide event security & security guards across our Academy Coffee establishments. Throughout this time, we have consistently received a professional and reliable service that gives us complete peace of mind. I would highly recommend Overt for any venue's security needs."
Daniel Hunt Commercial Manager Bellway Homes Limited (Building Safety) "I have worked closely with Overt for several years now. They have been providing waking watch services across a number of apartment blocks that we oversee. Throughout this time, we have consistently received a reliable and professional service from their team. I would be happy to recommend them to others requiring similar provisions."
Nick Pratt Director Ringley Group "I have worked with Overt for over five years, and they consistently provide waking watch, concierge, and security services across our sites. They are reliable, quick to respond, and always reassuring whenever they are on the job. I would highly recommend Overt and would not trust another company with our requirements."
Jeremy Griffiths Head of Security Cardiff Council "I have worked with Overt on a number of projects across the Council. They are very professional and demonstrate their full experience and expertise, particularly when it comes to more intrusive or complex jobs.
Steve, the Director, has never failed to impress me with the level of industry knowledge and support he provides. I would have no hesitation in recommending Overt for security-related requirements. "
