How Keystile protects it

Every Postmark action is checked before it runs, whether it comes from an AI tool or a workflow. 3 of its actions change data; your rules, limits and budgets decide whether each is allowed, held for a person or stopped, and it all goes into the signed record.

Tip

Write rules about what an action means — for example "Deleting Postmark records needs a person's approval" — rather than listing action names. Keystile Intelligence applies them to every action that fits.

Use Postmark with your AI assistant — safelyClaude, Cursor or ChatGPT do the work; Keystile checks every action first.
