# How does vendor federation simplify industrial access?

Vendor federation allows third-party technicians to use their own corporate identities to access specific resources on your network. This eliminates the burden of creating and managing hundreds of guest accounts and ensures that you do not have to store passwords for external users. By trusting the authentication performed by the vendor, you can focus on granular authorisation—deciding exactly what they can do—while maintaining a high degree of security and auditability. See our [case study on vendor access](https://www.agilicus.com/case-studies/vpn-alternative-for-securing-remote-access-to-legacy-hmi-plc/) for a real-world example.
