Oh yeah, you're right we haven't seen it like this yet. Although the point about SSO Tax is that you need to have the highest Enterprise plan to get SSO functionality at every SaaS tool. We just sell more features (not SSO) in another plan.
But I see your point. We should split and reorganise our plans a little bit. What's the feature you're interested in Enterprise?
The main feature missing is automatic user provisioning (your version of SCIM?). Access review is nice and also not just for enterprises, as many businesses today need to be SOC 2 / ISO 27001 compliant, but since its a quarterly process it's less critical.
I agree with you. SOC/ISO27001 became more popular. Even quarterly access reviews are already pain the more people you have. Documenting all the things is a lot of work.
However, feel free to try our product or contact us to get a live demo :-)
