Docs

Operational docs for public certificate monitoring.

Use these docs when you need exact behavior for monitor fields, CSV imports, alert delivery, signed webhook receivers, probe failures, team ownership, and renewal closeout checks.

Docs are organized around setup work: create the monitor, define the target, import a list, route warnings, sign webhooks, or diagnose a probe failure.

01Create the first monitor

Use Getting started when a workspace is new. It covers account setup, the first public hostname, immediate test behavior, alert-channel setup, and inviting backup owners.

Start setup02Define the TLS target

Use Monitor docs when you need exact behavior for hostname, port, SNI override, labels, tags, expiry thresholds, cadence, pause, resume, and test-now checks.

Read monitor setup docs03Import a hostname list

Use Import docs before committing a spreadsheet. The dry run explains accepted rows, duplicates, malformed endpoints, quota impact, and how tags preserve client or system ownership.

Read bulk import docs04Route certificate warnings

Use Alerting docs for expiry, expired, validation, certificate-change, retry, delivery-log, and dead-letter behavior across email, Slack, and signed webhooks.

Read alert routing docs05Build a webhook receiver

Use Webhook docs when certificate events should create tickets, update inventory, or enter internal workflows. Verify signatures and handle retries before acting on payloads.

Read signed webhook docs06Diagnose a probe failure

Use Troubleshooting when the result is DNS, TCP, TLS handshake, hostname mismatch, expired, not-yet-valid, trust-chain, or parse failure and the event needs the right owner.

Workspace evidence

Certificate health, routing, and ownership in one workspace.

The overview shows monitored hostnames, renewal pressure, certificate changes, and whether critical warnings reached Slack, email, or webhook routes.

Before setup

The docs explain product behavior. These links help you choose the operational path before configuring checks, alert routes, imports, or receivers.
