This part of the IAM space (SSO and AuthN) is so crowded with products, both paid and open source. When you look at governance, certification, lifecycle management, approvals, etc. there is almost nothing by comparison. A couple not so great commercial products and very little open source. Hopefully that changes.
What do you mean by these?
Are you talking about SOC2/ISO27001 when you say certification?
Are you talking about provisioning/deprovisioning users (SCIM, etc) when you say lifecycle management?
What do you mean by approvals? Role changes requiring designated approval, or something else?
