End-to-end Critical Connectivity

At CSL we have over 25 years' experience in managing Critical Connectivity services for the retail, automotive, healthcare and critical national infrastructure sectors. 

Over the course of the last few years we have become a more specialised Critical Connectivity company.  Our alarm signalling DNA and experience dealing with emergency services has helped us to build best in class IoT solutions for some of the world's largest and most complex organisations. 

As the UK's leading connectivity provider to the telecare, security and fire industries, we know that resilient connectivity means more than just uptime to the people who rely on it. It means understanding the impacts of change, and the alterations to environments that are needed as a result of that change. This trust, expertise and knowledge is accelerating our growth towards becoming Europe's leading Critical Connectivity provider.
