Self-hosted AD replacement that is AD-compatible and supports Windows+Linux SSO

Self-hosted AD replacement that is AD-compatible and supports Windows+Linux SSO targets a $8.0B = 10M organizations × $800 ACV total addressable market with medium saturation and a year-over-year growth rate of 12% YoY — identity & access management market CAGR per industry reports (IAM modernization, Zero Trust adoption).

Key trends driving demand: Zero Trust and least-privilege architectures are driving demand for stronger device-aware identity solutions — this increases interest in identity platforms that manage endpoints as well as app SSO.; Hybrid and multi-cloud deployments are increasing complexity for identity teams — this creates demand for portable, self-hostable identity layers.; Privacy and data residency regulations are encouraging on-prem and self-hosted options for critical identity infrastructure — this favors open-source or self-hosted alternatives.; Linux and macOS adoption on endpoints and servers is rising, so organizations need cross-platform identity solutions that don't prioritize Windows-only workflows..
