Real-time monitoring and response.

Epicenter is the Aftershock Security console. A lightweight agent on each host reports health, services and configuration every 60 seconds; the console correlates that into incidents, proposes a fix with its reasoning shown, and executes it once you approve, with a config backup taken first and an automatic rollback if the fix makes things worse. It also watches public endpoints from outside the network, so an outage pages us before a customer notices. It runs the entire Aftershock fleet in production, which is how we know what it does under load.
