Hi there,
For quite some time, excluding government agencies from your TPRM scope has generally been acceptable. Now that the new Interagency Guidance on Third-Party Relationships: Risk Management has been issued, it's reasonable to question whether regulators such as the OCC should be treated the same way as your other Third-Party Relationships. My answer is no.
The truth is organizations have limited practical options for managing risks associated with regulators (and similar government entities). This should, however, not be a great cause for concern.
Regulators are appointed by presidential administrations and governed under the oversight of Congress. Regulatory actions and agencies are subject to legal and legislative review. And while they serve an essential function in our government landscape, they should not necessarily be considered "critical" to your organization. Why? Your organization is held accountable for the third parties you choose to have a relationship with, and you have no choice regarding regulators. You also have no contractual relationship, no agreements regarding their performance, and no ability to influence their actions.
Interestingly enough, the OCC, for example, has listed a vulnerability disclosure policy https://www.occ.gov/about/policies/vulnerability-disclosure-policy.html that states, "We encourage security researchers to report potential vulnerabilities identified in OCC systems to us." And some other regulators post privacy policies on their websites. The point is, however, that these are not the same as actively participating in due diligence within your organization.
While Industry groups often work directly with elected officials and government committees to address their concerns over regulatory requirements or actions, it is not reasonable or practical to expect individual organizations to be responsible for regulatory agencies' safe and sound operations.
I recommend adding regulatory agencies to your inventory of third parties but excluding them from TPRM requirements as a rule. Focus your TPRM efforts on the third parties with whom your organization chooses to do business and where your time will be better spent managing the real risks to your organization and your customers. Those are my thoughts, but I would love to hear other members' thoughts.
