Put email sending on pause when secrets are exposed
A credential incident creates enough pressure already. Automatically protect a relevant address or stream while you investigate and rotate the secret.
Trigger
New Secret Scanning Alert Detected
Triggers when a new secret scanning alert is detected in a GitHub repository. Monitors open secret scanning alerts and fires an event for each newly detected alert. Supports filtering by secret type (e.g., personal access tokens, AWS keys) and by token validity status (active, inactive, unknown). The payload includes the alert number, secret type, validity status, resolution state, timestamps, URLs, and flags for push protection bypass, public exposure, and multi-repo detection.
Action
Create Suppressions
Tool to add email addresses to the suppression list for a message stream. Use when you need to prevent emails from being sent to specific addresses.
Why this helps
During an incident, founders may forget to stop an automated email from reaching an exposed or affected recipient.
- Adds a rapid containment step.
- Reduces accidental email delivery during investigation.
- Creates a repeatable incident response action.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Postmark to Notis once through the portal.
- 2Create an automation or ask Notis to add the specified affected address to the appropriate Postmark suppression list when a secret scanning alert is detected.
- 3Pick the new secret scanning alert trigger, choose a run-report channel, and test with a controlled alert example.
Questions about this workflow
Can this suppress every recipient?
Use a narrowly scoped instruction and verify the intended address or stream before enabling it.
Does suppression rotate the exposed secret?
No. It is a protective email action; credential rotation still needs to happen separately.
