Most CAs write events to a log and call it a day; the first notification anyone gets is the outage. goca ships notifications in the product: Slack, Microsoft Teams, email, ntfy.sh, generic webhooks.
And it ships them honestly. Events are recorded in the same database transaction as the change they describe — a rolled-back operation can never notify. Delivery is at-least-once, and every outcome, including suppressed by noise control, is a row you can read: "why didn't I get notified" always has an answer. A fresh install sends nothing anywhere — zero channels means zero egress, by construction.
You'll wire your first channel in Revocation, Notifications & Audit.
