How Nextcloud governance works in Rencore

Rencore connects to Nextcloud via the Nextcloud API and inventories instances, users, groups, shares, and apps. It links Nextcloud users to M365 users by email for cross-platform identity governance. Policies run on every scan cycle and flag sharing, lifecycle, and app issues.

Who uses Nextcloud governance

IT administrators use it to enforce sharing standards across self-hosted Nextcloud instances. CISOs review share policies to detect data exposure via public links. Heads of IT use reports to compare governance posture between Nextcloud and cloud-hosted collaboration platforms.

Frequently asked questions

What governance areas does Rencore cover?

Rencore covers six governance pillars: visibility and inventory across all Microsoft 365 services, ready-to-go policies with over 100 pre-built governance checks, compliance and audit evidence collection for regulatory requirements, extensibility and customization through custom policies and automations, cross-department collaboration with shared dashboards and role-based access, and AI and Copilot readiness to prepare tenants for secure AI adoption.

What is Rencore governance?

Rencore governance is a SaaS platform that continuously monitors your Microsoft 365 tenant for policy violations, configuration drift, and security risks across SharePoint, Teams, Power Platform, Copilot, and AI Agents. It automates compliance evidence collection, surfaces oversharing and sprawl, and provides actionable remediation workflows, reducing manual audit effort by up to 80%.

How do Rencore policies work?

Rencore ships with hundreds of pre-built policies that detect governance violations across every connector, oversharing, sprawl, cost overruns, security risks, and compliance gaps. Policies run on a continuous schedule, evaluate each discovered object against configurable rules, and flag violations with severity (High, Medium, Low), category, and a recommended action.
