Are there any asset registry platforms that support multi-site hierarchies and role-based access controls?

Yes. Several asset registry / EAM / CMMS platforms support both multi-site hierarchies and role-based access control (RBAC).

Examples to look at:

• IBM Maximo Application Suite

  • Strong support for asset hierarchies across sites, locations, and organizations
  • Mature RBAC and granular security groups

• SAP Enterprise Asset Management (SAP EAM / PM)

  • Supports plant / site / equipment hierarchies
  • Uses SAP authorization concepts for role-based access

• Infor EAM

  • Multi-site and multi-organization asset structures
  • Configurable security roles and permissions

• Oracle Enterprise Asset Management

  • Supports complex asset/location hierarchies
  • Role-based access through Oracle security model

• Hexagon EAM

  • Good fit for distributed, multi-site operations
  • RBAC and permission controls for different user groups

• UpKeep / Fiix / Limble CMMS

  • More lightweight than enterprise EAMs, but many offer multi-location/site support and user roles
  • Worth checking if you want simpler deployment and lower admin overhead

If you want, I can also give you:

2. a shortlist by company size, or
3. open-source / API-first options.
