About Us

We have been successfully providing security and facilities management (FM) services since 2001.

Our role is to support your business and ensure it operates as smoothly as possible, especially in these volatile times.

When we started out in the security business back in 2001, our business was simply called ‘Mercury Security Management’; over the years we have evolved and added additional services to our portfolio . We have become one of Ireland’s largest independently owned security and facilities management companies, with clients ranging from global blue-chip companies to local SMEs.

From our beginnings in Northern Ireland we have grown and now have offices in Dublin, Limerick and London. Throughout this period of continual growth we have always been passionate about delivering the right solution to every client we work with. Today, we deliver tailor-made, cost-effective security & FM solutions for all our clients across a broad range of industry sectors, including:

Retail, Banking, Government, Entertainment, Real Estate, Construction, Hotel and Leisure, Health, Public Services, and Transport.

We employ hundreds of highly skilled staff across the UK and Ireland, all of whom are continually trained in our Mercury Training Academy; this ensures that clients consistently receive the same, focused customer service experience.
