Fetching a certificate is not enough. The tool must know which IIS binding to update and how to verify that HTTPS works.
The key elements are validation, SNI, permissions, logs, renewal schedule and expiry alerts.
For public Windows Server services, eTop, Hostilla and DataHouse support can connect certificates with infrastructure monitoring.
For everyday hosting, start with Hostilla. For dedicated infrastructure, servers or colocation, continue with DataHouse.
