3 ways custom scan checks turn practitioner knowledge into scalable automation
PortSwigger outlines a methodology for turning manual pentest heuristics into Burp custom scan checks so the same detection logic can run across large application and API estates. The article focuses on operational use cases rather than a new vulnerability: converting fresh CVE or 0-day proof-of-concept logic into reusable checks, codifying environment-specific rules such as missing tenant-context enforcement on headers like X-Tenant-ID, and hunting for exposed secrets in responses, JavaScript bundles, .env files, and source maps. It also highlights using Burp Collaborator in active checks to detect out-of-band issues that require external interaction rather than simple in-band response matching. The practical takeaway is that teams can preserve senior tester knowledge as reusable scanning logic and push it from Burp Suite Professional workflows into broader DAST coverage, improving consistency and response speed during emergency triage.
