Check services that sit behind your firewall. Run a small agent inside your network and it reports results over an outbound connection, so no inbound ports need opening.
Private checks behave like any other monitor, with the same rules, schedules and status pages.
Requirements
One small container or a single binary
Outbound HTTPS on port 443
A separate key for each agent, which you can revoke at any time
Next release
Duplicate Slack messages
