Building a Unified Enterprise Identity Platform and Cloud Foundation for Toyota North America
How can a global automotive leader unify identity management and modernise cloud infrastructure without disrupting critical operations?
Toyota North America faced a growing infrastructure challenge: identity and access management was fragmented across multiple legacy systems, with no unified IAM platform in place. These systems operated in silos, disconnected from modern applications and cloud services, creating security blind spots and operational inefficiencies.
As the organisation scaled, the lack of a central identity layer increased risk, complexity, and maintenance overhead. Managing user access across departments, systems, and applications required manual intervention and custom integrations, making governance and compliance increasingly difficult.
At the same time, Toyota's Azure-based infrastructure was becoming costly and difficult to scale for an organisation of this size. The existing setup limited flexibility and introduced unnecessary expense, particularly as workloads and identity demands continued to grow.
Toyota engaged Westpoint to design and deliver their first-ever enterprise Identity Access Management system for North America—one that could unify identity across legacy and modern platforms without requiring a full replacement of existing applications. In parallel, we were tasked with leading a strategic cloud migration from Azure to AWS to improve scalability, resilience, and cost efficiency.
A unified enterprise IAM platform paired with a scalable, cost-optimised AWS cloud architecture.
Westpoint partnered closely with Toyota North America to architect a secure, non-invasive identity platform and execute a large-scale cloud migration—delivering enterprise-grade capabilities while protecting existing systems and operations.

The result
Enterprise-wide identity unification
Toyota eliminated identity silos across North America, gaining a single, authoritative identity layer spanning legacy and modern systems.
Significant long-term cost savings
The new cloud architecture delivered an estimated $45 million in savings over five years, driven by improved scalability and infrastructure efficiency.
Reduced operational and maintenance burden
By avoiding full legacy replacement, Toyota dramatically reduced system maintenance overhead while improving governance and security.
Scalable, future-ready cloud foundation
The AWS platform now supports enterprise-grade scalability, enabling Toyota to evolve identity, security, and digital capabilities with confidence.
