Hi there,
Your list of questions is a great starting point. However, one of the best benefits of onsite reviews is that is allows you gain a firsthand view of risk management practices and controls that aren't always the focus of vendor due diligence questionnaires or documentation. For example, if you are talking about the vendor's third-party risk management practices, it's a great time to ask them for evidence of their processes. That might look something like this:
How do you monitor and assess the resilience of your own critical third parties (4th parties) involved in payment processing?
• Ask them to pull the list of their critical third parties, select two critical vendors at random and ask to see the risk and control reviews for those vendor's BCP/DR plans.
What mechanisms are in place to ensure that 3rd parties (our 4th parties) meet our compliance and security standards?
•Ask them to see their process documentation that details how 4th parties are reviewed, who is reviewing them, their qualifications and if they have any examples of vendors who did not meet the standards.
How frequently do you perform risk assessments for your 3rd parties (our 4th parties), and what specific metrics do you track?
• Ask to see their risk-based re-assessment schedule and reporting detailing on-time completion
How would you notify us if a 4th-party vendor experiences an outage or breach that affects your services to us?
•This should be part of your contract, but you could ask to see their standard contract language requiring vendors to notify them in case of a breach. And double check to see if that language exists in a few critical vendor contracts pulled at random
Onsite visits are also a great time to talk to the vendors' management team and employees (beyond your representative) to discuss their understanding of third-party risk management practices and to gauge their internal risk culture.
Because no-one likes surprises and to be courteous you should set some expectations with the vendor before the visit, mentioning that that you would like to review evidence of their processes. Giving them enough notice will help ensure that relevant employees are available during your visit, but I would not necessarily detail everything you want to see in advance. You will want to see firsthand how organized they are and how quickly they can respond.
Those are some of my thoughts, but I would love to hear from other members.
