Insights
Upcoming rotations, stale secrets, reminders, and who has been reading what.
Webhooks
Call an endpoint of yours whenever a secret changes.
Events subscriptions
Subscribe to a stream of project events instead of polling for them.
Monitoring
Find problems in a project, and get told when its secrets change.
Insights look inward at the state of a project. Webhooks and event subscriptions look outward, carrying secret changes to systems of yours that need to react to them.
