Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Datto SIRIS

  • Initial setup and hardware costs can be substantial for smaller MSPs

Nextcloud

  • Requires self-hosted deployment on organisation-controlled infrastructure; no managed cloud option provided by Nextcloud
  • Operational overhead: organisations must apply security patches, manage backups, configure SSL certificates, and handle system administration
  • Scalability challenges at very large user counts (10,000+); requires careful database and storage tuning
  • Mobile clients lack some features of web interface (scripting, advanced admin functions); feature parity varies across platforms
  • Integration with Microsoft 365 and Google Workspace is limited; Nextcloud does not replace Exchange or Gmail directly
