What Guardian does
Guardian puts a checkpoint in front of risky steps such as payments, outside emails or changes you cannot undo. It checks the action itself against your rules, like amount limits, approved recipients or changed bank details, before anything runs. Teams, projects and roles decide who can approve what, and you add it to an existing workflow without rebuilding it.
Who Guardian is for
- Operations managers
- Finance managers
- Automation builders
- IT administrators

- Rules for amount thresholds, recipient allowlists and changed bank details
