BEFORE YOU ASK FOR A QUOTE01 / THE SYSTEM 02 / THE ENGAGEMENT 03 / THE EVIDENCE
Make the assessment specific.
An agent is more than a model.
Document its tools, permissions, data sources and approval steps. Those connections determine what an assessment needs to exercise.
Ask what is actually included.
Confirm test identities, safe actions, deliverables and retest terms. An architecture review and a live adversarial test answer different questions.
Buy findings you can act on.
Request a sample report. Look for reproduction conditions, observed impact, clear limits and a way to verify the fix.
