Case Study: Oldcastle Infrastructure achieves centralized remote vendor access and stronger security with Imprivata SecureLink

Oldcastle Infrastructure, Inc. uses Securelink to manage vendor privileged access for multiple users across 85 locations

Oldcastle Infrastructure, a leading North American manufacturer of utility and construction products and part of the CRH group, faced fragmented and insecure remote vendor access across 85 sites. Multiple VPNs and screen‑sharing tools left the company unable to monitor or control third‑party credentials and activity, creating security and compliance gaps and a need for a standardized, centralized privileged‑access approach.

Oldcastle implemented SecureLink’s vendor privileged access management platform to centralize vendor logins, enforce two‑factor authentication, vault credentials, and record and audit sessions. The rollout—aligned with other CRH divisions—was smooth, delivered centralized support, stronger access controls and visibility, and proved a justified investment that improved security, efficiency, and consistency across the enterprise.
