Start with the decision you need to make: validate an application or network, build a security program, operate detection, prepare for an incident or respond to one already underway. These are different mandates. Ask who will personally do the work, what is subcontracted, how testing is authorized and stopped safely, where evidence lives, how critical findings escalate, whether detection is tested, what the incident clock means, and whether remediation verification is included.
