40 domains, none expires by surprise: SSL, DNS and renewals under control
One list of all domains with owners and registrars, warnings 30 and 7 days before expiry, and an alert on any unexpected DNS change.

to notice a DNS change
This is a solution example: it shows how we would build it for a typical client. The figures are targets we agree on before the work starts, not results of a specific client.

The problem
A client's site and mail went down for two days because the domain expired — the renewal email went to a former employee.
How we solve it
- 01Inventory: every domain, registrar, owner and renewal date
- 02Daily check of expiry, SSL certificates and key DNS records
- 03Telegram and email warnings 30 and 7 days ahead
- 04Alert when MX, A or NS records change unexpectedly
