4sl specialise in high-performance backup and DR managed services for firms in regulated sectors. 4sl is headquartered in London and 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: 1) 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. 2) Data Custody & Availability – As the traditional, vertical IT infrastructure stack is eroded by hyper-converged and public cloud, we believe the future will be oriented around data.
