Approach Useful question Procurement detail that matters Limit
Vulnerability scanning Which known weaknesses may be present? Authentication, asset reach, frequency and validation Findings can need investigation and prioritization
Scoped penetration test What can an authorized tester demonstrate within this scope and window? Roles, manual depth, business logic, rules of engagement Time-bound and limited by scope
Continuous testing/PTaaS How will testing and validation recur as assets change? Cadence, actual tester involvement, credit model, retests A recurring subscription still has coverage limits
Adversary exercise/red team Can the organization detect and respond to agreed objectives? Safety constraints, objectives, deconfliction and evidence Unsuitable as a substitute for fixing basic known gaps

These are buyer-oriented distinctions; service definitions vary. Bishop Fox's service menu and NetSPI's testing categories show the breadth hidden inside “pentest.” Require a sample deliverable and a written scope rather than assuming equivalent depth from similar labels.
