Vendor Security Assessment Service


The Information Security Office (ISO) offers a Vendor Security Assessment (VSA) Service for Vendor contracts that involve Vendor access to UC systems or to data classified at Protection Level P3 or P4.  The purpose of the VSA Service is to determine whether the Vendor’s security plan is adequate to safeguard UC systems and data. At the conclusion of the service, a report will be provided to the requesting party including an overall risk rating, risks, and recommendations. A typical VSA takes 4 - 6 weeks to complete starting from the date the Vendor has provided all the information requested to perform the VSA. Please plan accordingly.

Roles and Responsibilities

The campus roles that typically participate in a VSA include the following:


The Requester is responsible for:

  • Filling out the VSA form

  • Managing the relationship with the Vendor; including coordinating and communicating with the Vendor to ensure ISO and Venminder have all information required to complete the VSA.

  • Responding to questions that arise during the VSA. The Requester should possess a sufficient understanding of the Vendor’s service and the Unit’s use case in order to respond to questions that may arise during the VSA. 

  • Informing and coordinating with the Unit Information Security Lead (UISL) and Unit Head to decide how risks identified in the report should be managed; It’s rare that a VSA contains no security concerns.
