About us

About 4sl

4sl is a UK company, headquartered in London, focused on data custody and availability services for mid-size and enterprise firms. Our clients include several FTSE100 and FTSE250 companies with operations from North America to South East Asia.

Our vision is founded on two simple concepts:

 

As a Service – For most firms, IT is not their core business. Public cloud and SaaS have demonstrated that consuming IT as a service can be far more desirable than managing in-house. We take that idea one step further to deliver complex, on-premise offerings as-a-service to make our clients’ lives easier.

Data Custody & Availability – As the traditional, vertical IT infrastructure stack is eroded by hyperconverged and public cloud, we believe the future will be oriented around data.

 

In 2013 and 2014 we were listed in the Sunday Times Tech Track top 100 fastest-growing private IT companies.
