Cesivi.

On-premises · protocol-compatible · self-hosted

Cesivi — on‑prem collaboration that speaks your existing protocols.

A drop-in, on-premises collaboration platform that speaks the protocols your estate already runs on — REST, CSOM, SOAP, and PnP PowerShell — so your existing tools, scripts, and migrations just work. Keep the proven feature set; run it on a modern, self-hosted stack you control.

Coming from SharePoint on-premises? Cesivi implements the same protocol surfaces, so the scripts, CSOM applications and PnP provisioning you already run keep working unchanged.

Why Cesivi

Not a lookalike. The actual protocol surface.

Everything that talks to your on-prem estate today keeps talking to Cesivi tomorrow.

01

Protocol-compatible, not a lookalike

Real REST/CSOM/SOAP/PnP surfaces — your SharePoint scripts, CSOM apps, and PnP provisioning run unchanged.

02

On-prem, self-hosted, yours

Runs on Linux or Windows/IIS. FileSystem, SQL Server, PostgreSQL, MySQL, SQLite, or LiteDB storage — your infrastructure, your data.

03

Migrate off an aging on-prem estate

Import your content from SharePoint on-premises; keep lists, libraries, content types, permissions, and web parts intact.

04

Modern where it counts

A face-lifted UI over the classic feature set — better looking, same concepts your users already know.

What's inside — v2 capabilities

On the roadmap — not shipped yet

Planned, clearly labelled.

These are in development or preview — deliberately kept out of the spec sheet above so nothing there is a promise. Timelines indicative.

Security · SSO
SAML / WS-Federation enterprise SSO — passive-profile assertion validation and claims mapping. Preview; disabled by default.
Preview
Security · mTLS
Client-certificate (mutual-TLS) authentication — map an X.509 client cert to a Cesivi identity. Preview; disabled by default.
Preview
Protocols & APIs
GraphQL write mutations (create / update / delete) over the native GraphQL endpoint — the read API ships today.
Roadmap
Scale & HA
Kubernetes operator + Helm chart for declarative farm and tenant provisioning. The K8s-free scale-out path (multi-instance + load balancer) ships today.

Migration path

Migrating off an aging on-prem estate

Point your SharePoint on-premises migration at Cesivi and bring your content across.

Lists, libraries, content types, permissions, and web parts are preserved. Your PnP provisioning scripts and CSOM tooling keep working against the same protocol surface.
