Nacoss and MJ Security Systems
What is the National Security Inspectorate (NSI)?
NSI has been the UK's leading inspectorate for the security industry for over 35 years. As an independent, not-for-profit organisation, NSI is the champion of high standards in the security industry. Companies achieving approval through NSI must comply with relevant British and European Standards as well as meeting the requirements of the police and insurance industry.
Why are NACOSS Gold companies the best?
NACOSS Gold is only awarded to a company after rigorous checks have been conducted. These companies must display a satisfactory combination of technical expertise and business excellence.
