Case Study: HighSpeed1 achieves faster, more secure collaboration and mobile productivity with Office 365

UK Railway Concessionaire Connects People and Destinations in Record Time With Cloud Solution

HS1 Limited is the London-based concessionaire that operates the High Speed 1 rail link between St Pancras and the Channel Tunnel. With just 50 employees and a two-person IT team, the company needed a scalable, highly secure way to collaborate with hundreds of vendors and regulators, replace an unreliable hybrid cloud that suffered outages and outdated tools, and meet strict data‑protection requirements such as GDPR.

HS1 migrated to Microsoft 365 E5 (including Office 365, SharePoint Online, Azure AD Premium P2, advanced threat protection, and Power BI) with implementation help from partner Perspicuity and rolled out Microsoft Lumia devices for a more mobile workforce. The move delivered a single version of the truth in SharePoint, stronger identity and threat protection, reduced downtime and infrastructure costs, faster collaboration with external partners, better operational reporting, and greater readiness for regulatory compliance.
