Phaseone was formed in 2007 by our directors who wanted to put their skills and knowledge to the forefront of the security industry. We focused on providing security services to small venues in the East Sussex area. Since then we’ve grown into a multi-regional security provider, catering to a range of big name brands, private customers and government organisations. But throughout this process we haven’t lost touch with our roots, and we continue to pride ourselves on the quality of our customer relations, as well as our services.

That’s why with Phase One Security you can find the flexibility you need, whether you’re looking for man power for an event, or ongoing professional cover for a corporate premises.
