Kerdos OS
One sign-in. One source of truth. The platform our companies run on.
Kerdos OS is the private operating platform every Kerdos and Cedar Group company runs on — identity, work, knowledge and communication behind a single sign-in, owned end to end rather than rented from a dozen vendors.
We built it for ourselves first. It is stable, self-hosted and multi-tenant by design — which is exactly what would make it productisable, if and when we choose.
What it does
One identity
People sign in once; access follows them — and ends cleanly the day they leave.
One source of truth
Work, code, docs and conversation live together, not scattered across disconnected apps.
Sovereign by default
Self-hosted and owned, so the data and the uptime are ours to stand behind.
Controls & governance
Controls are designed in, not bolted on.
- Maker-checker on sensitive changes; segregation of duties by role.
- One identity, least-privilege access, and clean offboarding the day someone leaves.
- Everything auditable — who did what, and when.
The principles behind it
- Built to outlive the people who started it — documented, durable, institutional.
- Multi-tenant from the first line, so a new company is configuration, not a rebuild.
- Owned, not rented — control over cost, data and reliability.
Trust & compliance
- Security and access are designed in, not bolted on.
- It runs real operations today — this is not a concept.
This is our internal infrastructure and among our most sensitive IP. What we share publicly is intentionally limited; under NDA we can go further with serious partners.
