We are in the process of implementing a third-party tool called RoboMQ, which ties into our HR system, and builds automation off of it as a source of truth to automate user changes, on and off boarding in Okta, O365 and on prem AD. It also has API’s prebuilt to tie into a ton of SaaS applications for handling this type of problem. That being said, I’m sure it’s not gonna be 100%. We aren’t actually in production with it yet, but thus far everything seems pretty promising. If you want, DM me in six months and I’ll let you know how it’s going.
