Custom scan checks
Burp lets you define passive and active scan rules in BCheck format or via the custom scan checks API.
Caido lets you define custom checks through the Scanner plugin's check definition API for active and passive vulnerability detection. Caido also supplements this with Passive Workflows for traffic-level rules that run on every request. Caido splits scanning between the Scanner plugin (issue detection) and workflows (traffic analysis) rather than a single BCheck format.
