Self-hosted model boundary

In self-hosted deployments, you choose and operate your own infrastructure and provider stack. You define subprocessor scope for the components you host.

Change management baseline

  • Subprocessor changes follow internal review before customer use.
  • Tero communicates material changes that could affect security, availability, or data handling in advance where required by contract or plan terms.
  • Tero communicates emergency changes, with impact context, as soon as it understands the impact.
