Automating user provisioning and deprovisioning is crucial for companies to increase product adoption and mitigate security risks, as it enables the seamless addition and removal of users from a platform. This process involves automatically assigning permissions and access to new users and revoking them when an employee leaves, typically initiated through integrations with HRIS solutions. Companies like Ramp, AngelList, and BILL have successfully automated these processes, resulting in enhanced user experiences, improved customer retention, and increased close rates. The benefits of automating user provisioning and deprovisioning include protecting sensitive information, streamlining user management, and delivering faster time to value. To achieve this automation, companies can utilize tools like embedded iPaaS or unified API solutions, such as Merge's Unified API, which offers a scalable and efficient way to build HRIS integrations and access multiple categories of integrations. By implementing automated provisioning and deprovisioning flows, businesses can improve their overall security posture and provide a better experience for their customers.
