How to choose a penetration testing provider

Check what is in scope (web app, API, cloud, mobile), who does the testing, and whether the report is acceptable to your auditor. Ask about re-testing after you fix findings.

Some providers are firms with testers on staff and some are platforms that match you with testers. Both can work, so ask who is accountable for the report.
