WebOverwatch is a domain monitoring and security service that watches the domains you own and tells you the moment something changes.
It keeps an eye on the things that quietly break websites: DNS records being added, swapped, or removed; SSL/TLS certificates drifting toward expiry; and domain security signals shifting without warning. When something moves, WebOverwatch sends an alert — so you find out from your monitoring, not from a customer.
Domain-level problems are easy to miss and expensive to ignore. An expired certificate throws browser warnings in front of every visitor. An unexpected DNS change can mean a misconfiguration, a lapsed transfer, or a hijack. These rarely announce themselves, and by the time they surface the damage is already public.
Point WebOverwatch at the domains you care about and let it watch them continuously. It is built for developers, agencies, and teams who manage more domains than they can reasonably check by hand.
