For IT.
What it needs. A Linux or Windows server with Docker, 2 CPUs and 4 GB, and a SQL Server 2019 or later instance you already back up. Two containers. The application login has no DDL rights; migrations run under a separate one your DBA controls.
Sign-in. Entra ID, Okta or any OpenID Connect provider, set up from an admin screen with a Test button. A local password for the first administrator until that's done.
Nothing phones home. No telemetry, no licence server. The licence is a signed file; if it lapses you get a notice, then a 30-day grace period, and even after that nothing in progress is locked.
Tested at 100,000 people and 100,000 records on one small VM: queue and record pages under 0.2 seconds, search about half a second.
