CAS-004 Practice Question: A financial institution is adopting a new…
A financial institution is adopting a new vendor-managed SaaS platform for customer data processing. The CISO wants to ensure the vendor's security controls meet regulatory requirements before data is transferred. Which of the following should be completed FIRST?
⚠ Common exam trap
The trap here is that candidates often jump to technical testing (penetration test or vulnerability assessment) as the first step, overlooking that governance and compliance require a contractual and risk-based evaluation before any hands-on technical engagement is permitted.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform a third-party risk assessment.
Before transferring sensitive customer data to a new vendor-managed SaaS platform, the CISO must first perform a third-party risk assessment to evaluate the vendor's security posture against regulatory requirements (e.g., GDPR, PCI DSS). This assessment reviews the vendor's SOC 2 reports, ISO 27001 certification, and contractual security controls, ensuring compliance before any technical testing or data transfer occurs. Without this initial risk evaluation, subsequent technical controls like penetration tests or DLP may be premature or misaligned with regulatory obligations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Execute a penetration test on the SaaS platform.
Why it's wrong here
Penetration testing is a detailed technical evaluation that should occur after initial risk assessment.
- ✗
Implement data loss prevention controls.
Why it's wrong here
DLP controls are implemented after assessing risks and defining requirements.
- ✗
Conduct a vulnerability assessment of the vendor's network.
Why it's wrong here
Vulnerability assessment is a technical control that should be performed after a risk assessment determines the need.
- ✓
Perform a third-party risk assessment.
Why this is correct
Third-party risk assessment evaluates the vendor's security controls and compliance before data transfer.
