Case Study: NS&I achieves 33% time savings on third-party risk assessments with Prevalent

How National Savings and Investments Secures Its Supply Chain for the Future

NS&I is one of the largest savings organizations in the UK (25 million customers, more than £179 billion invested) and, as an arms‑length government body, must meet strict public‑sector and financial‑services third‑party risk requirements including bi‑annual SYSC 8 audits. Managing up to 250 suppliers with a manual, spreadsheet‑based assurance process was labor‑intensive and unsustainable, so NS&I turned to Prevalent and the Prevalent TPRM Platform to automate and simplify supplier assessments.

Prevalent implemented its Third‑Party Risk Management Platform to automate questionnaire design, distribution, chasing reminders, and to centralize supplier answers and evidence while simplifying SYSC 8 reporting and enforcing supplier accountability. The result for NS&I was at least a 33% reduction in person‑hours for third‑party risk assessments, much faster procurement workflows (teams can identify vendors, contact account managers, and send surveys in about a day), smoother annual renewals, and extension of the platform to outsourced partners, delivering clear time savings and a rapid ROI.
