Meridian is built for teams with a handful of agents and several customers, not for a hundred-agent help desk. It keeps the service desk and the monitoring in one place, so you can see what is broken and who is waiting for it at the same time. A ticket knows which customer it belongs to and which SLA applies, and a failed check becomes an incident without anyone filling in a form. Tenant isolation is enforced in the database as well as in the application, and every change goes into an audit log.
Looking after customer platforms means answering tickets, watching services and billing the hours spent. Meridian grew out of that work.
