Direct answer
Compare proposals against the security questions and assets you need assessed. Look for explicit targets, roles, methods, evidence, limitations, communication and retest terms; ask providers to clarify gaps before selecting an engagement.
Describe the required outcome
For a SaaS product, decide whether the priority is cross-tenant access, a new API, infrastructure exposure or a broader combination. Provide a representative inventory and expected roles to each provider so proposals address the same decision.
Reference: NIST SP 800-115: Technical Security Testing and Assessment.
Compare coverage
Check environments, domains, API versions, authentication roles, test duration and excluded third-party services. A proposal for an automated public scan and one for an authenticated manual test can have very different scope even if both use the word pentest.
- Ask for assumptions and exclusions in writing.
- Clarify safe methods, test accounts and change windows.
- Identify how unavailable paths will be reported.
Review evidence and communication
Ask for a sample report showing impact, sanitized evidence, confidence, remediation and coverage. Agree escalation for serious findings and secure delivery of the final report. Check whether a retest is included and what it covers.
Reference: NIST SP 800-115: Technical Security Testing and Assessment.
Evaluate the operational fit
Confirm the organization's ability to provide accounts, contacts and safe fixtures. Compare delivery timing, dependencies and responsibilities alongside cost. No proposal should promise that a point-in-time assessment finds every vulnerability or guarantees compliance.
Assessment limits
A proposal comparison does not establish a provider's performance. Evaluate references and contractual terms appropriate to the organization's procurement process.
Frequently asked questions
Are all pentest proposals equivalent?
No. Compare targets, roles, techniques, time, exclusions and deliverables to understand what will actually be assessed.
Does a report guarantee compliance?
No. A security assessment may provide evidence for a broader compliance process but is not automatically certification.
