 Our Story

With over 25 years of innovative engineering experience, Grosvenor Technology is a market leader in Access Control and Workforce Management solutions.


Based and founded in the UK, Grosvenor Technology has offices in Stansted, Essex and Poole, Dorset as well as a North American office in Hollywood, Florida and our recently opened offices in Hong Kong. This international presence enables us to offer global support in our customer’s time zone and language.

We were the first UK manufacturer to offer an access control front-end in a Windows environment and our JANUS, Siteguard and Sateon products have become bywords for access control in the security industry.

Since 1989, thousands of systems have been installed across the globe and we have built an impressive blue chip client list, which includes Argos, H&M, Tesco, Bank of America and BAE Systems. Our experience in the marketplace spans businesses in a range of sectors including Education, Retail, Banking, Healthcare, Infrastructure, Commercial and Governments.

Innovative products come as standard but what really makes us stand out is our service. Not only have we built an impressive customer base but we have maintained our relationship with many of them for over two decades thanks to an ongoing technical support service that begins at specification and continues for as long as we maintain your business.
