Case Study: Invensys Rail eliminates password lockouts and boosts productivity with Imprivata OneSign

Locking Down Access Management

Invensys Rail, a 150‑year leader in railway signalling, was struggling with employee access to up to 20 different applications—each with separate logins and frequent timeout requirements. Staff regularly forgot passwords, wrote credentials down, and were locked out, generating heavy helpdesk load (814 reset workflows in nine months), reduced productivity, and increased security risk.

Invensys deployed the Imprivata OneSign appliance with biometric single sign‑on and self‑service password reset, rolling out 1,500 users across multiple sites in six weeks without changing application structure. The solution supported legacy and remote users (offline caching and failover), enabled access tracking for audits, delivered a 98% positive trial rating, cut helpdesk calls, saved users up to 15 minutes per day, and produced rapid productivity and security gains.
