The story and vision of David Graffham

"After nearly 30 years in the security industry I started Delta Security Management because I am genuinely passionate about making sure that our clients, and our workforce, are treated like superstars!

By providing you with the highest level of service and confidence that you and your business deserves, and going way beyond expectations, your security needs are always covered meaning you can sleep better at night with us looking out for you, your premises, your stock and equipment and your staff. 

It doesn’t stop there for me. Whilst we work hard for our customers it is also important to me that we give back to communities in which we operate and earn a living. Supporting good causes and helping where we can is a foundation of Delta Security Management."
